Somewhere in a parallel universe, this weekend Dave Grundy and I would just have been saying goodbye to a group of moth-ers and wildlife lovers, having spent a week enjoying Andalucía’s lepidopteran delights!
Here’s a heartfelt message from renowned moth expert Dave, as well as some stunning photos to look back on from the excellent trip he hosted here in 2019…
So, this week I am sad, even though I am living in Andalucía and able to look at some great moths every morning, with beautiful sunshine as well! That’s because with fellow leader Niki Williamson, I should have been hosting ten moth enthusiasts last week, to show them the moths of Andalucía in our holiday called Mothing the Straits!
We would have completed six days’ worth of glorious mothing – and a further four days enjoying the area’s birds and other wildlife for those that wished to stay on. But unfortunately, due to the coronavirus situation we had to cancel this year’s holiday. I am really gutted not to have been looking at moths with these people!
And I am sad because I am never happier than when I am sharing moths with other people and I’ve not been able to do that since lockdown began! So, I thought I would do the next best thing and show you some photos of the fantastic selection of the moths we saw on this trip in 2019, as well as some of the sites and the crack team of moth-ers!
Hopefully they will inspire you to consider coming with us on the same Mothing the Straits holiday next year – we already have announced dates for 2 – 7 May 2021. But book early because places are already filling fast. Take a look at further details here, and download the checklist and trip summary here.
Again, like this year, you will have the optional extra of being able to stay on for four more days and take advantage of a birding and wildlife-watching extension. Over half the people booking on the moth tour usually book for the extension as well! And this is a stunning part of the world to view wildlife, famous for its migrating raptors, cetaceans, butterflies and reptiles as well as its moths!
So, although I’m sad about this year, I’m already looking forward to next year, why not give it a try and maybe I will see you next May?!
We hope you can join us! We are currently accepting no-obligation provisional bookings on future trips – contact us to express an interest or to find out more information on this or any of our trips.
A young Italian called Michele caused a frisson of excitement here in The Straits last month, turning up safe and well after being missing in Africa since mid-November! Not long after his reappearance he was on his adventures again, awaiting fine weather on the northern shores of Morocco before jetting across the Straits and spending the night just outside Sevilla.
The plucky individual is a young Short-toed Eagle, satellite-tagged in 2019 as part of a collaboration between MEDRAPTORS, the Vertebrate Zoology Group at the University of Alicante (Spain), and tag providers Tecnosmart. He is a second-generation project participant – his father Egidio was one of seven young eagles tagged between 2010 and 2013, who reached adulthood and bred successfully in 2019 while still transmitting data.
This father-son team continue to shed light on the surprising and convoluted migration of Short-toed Eagles from Italy. The two-kilo eagles wear their tiny GPS tags on their backs, and the fascinating story they tell has confirmed what many suspected. Instead of beginning the journey to their wintering grounds in sub-Saharan Africa by heading directly south to Tunisia, they start with a 1600-mile flight north and west, right up through the Italian Peninsula and across southern France, before crossing the Pyrenees and migrating down through the length of the Iberian Peninsula, more than doubling their journey distance to Africa´s shores.
The reason? it´s all about wings and Straits.
The long, elegant wings of this beautiful raptor mean it is perfectly adapted for soaring on air thermals, and it can do so for many hours, expending very little energy. But where there is no rising air – such as over expanses of water – the bird must beat those long wings to stay airborne, and becomes quickly exhausted.
Leaving the south-western point of Sicily, where Italy is at its closest to Africa, the bird would have to fly almost 100 miles to the next bit of land – an impossibility for such a long-winged raptor. So Italian Short-toed Eagles have learned to go directly against their strong instinct to head south, forcing themselves to fly north in order to eventually arrive in southern Spain. Here the mere 8.5-mile sea crossing at The Straits of Gibraltar presents much less of a challenge to a healthy, experienced bird choosing the right weather conditions.
While southerly migratory behaviour is innate, the study shows that this northerly trek must be learnt. First-year birds follow an adult who has already learnt the circuitous route to avoid the sea. Around 20% of first-year birds get it wrong and follow their hearts south, ending up wintering on Sicily because there is no more “south” to fly.
Michele was named after the late Michele Panuccio, the raptor researcher who studied the species for several years and promoted the tagging of Egidio’s first son, who was tagged a few weeks after he passed away. He left the nest site at the end of September, several days before his father, presumably following another adult bird. No doubt aided by years of experience, Egidio left late but made the journey in considerably less time. By the end of October, he had already arrived in Mauritania while Michele was still taking it easy in Extremadura!
When the lazy adolescent did finally make the crossing, the signal from his tracker was soon lost as he moved out of areas with the mobile coverage necessary to follow him. For the research team, there was nothing more to do except wait and hope that he had found his way to the wintering grounds safely. So when his tracker was spotted on the move again earlier this month, it must have been a tremendous relief!
His northward crossing of the Straits was unusual behaviour for such a young bird, as non-breeders would normally stay in Africa for another year, “finding themselves” until they come of age. Interestingly though, back in the day, dad Egidio was also a precocious exception to this rule – he too returned to the breeding grounds as a one-year-old.
This year, seven-year-old Egidio was no less keen to breed, and started his migration back to Italy as early as mid-February, arriving there by 12 March! In early March we spent some absolutely joyous days here in the Straits of Gibraltar, watching raptors arrive across the narrowest stretch of sea between Europe and Africa. We clapped them all as they arrived on our shores! We´d love to think that Egidio was one of them…

The eBird database just received a significant boost, in the form of information on almost two million migrating birds from our conservation partners, Fundación Migres!
Many is the joyous day we’ve spent with our conservation partnersFundación Migres, helping with the autumn migration count, gazing up spellbound as literally thousands of raptors migrate over our heads. Horizontal in deck chairs, to the casual observer the team of volunteers must look super-relaxed, but often this couldn’t be farther from the truth! Raptor species and sections of sky have been allocated, clickers have been distributed, and now it is our responsibility to painstakingly count the mind-boggling numbers of migrating soaring birds crossing the Strait of Gibraltar, ensuring our contribution to the Migres legacy is a worthy one.
This work of science and passion combined began over twenty years ago in 1997, making it one of the longest running avian migration monitoring programmes in Europe. The importance of the data it generates cannot be over-emphasised – around three-quarters of the soaring birds that breed in Europe pass through this migration bottleneck, including endangered species such as the Egyptian Vulture. The vast quantities of data generated by the counts carry a powerful amount of information about the fortunes of these birds.
And now, in a big step to make this data more available, several years’ worth have been digitised and uploaded to eBird! All the data generated by the Migres Program from the autumn monitoring campaigns for soaring birds (raptors and storks) 2012-2016 and seabirds 2012 -2013 is now on the site.
The data include over 90,000 records of over a million-and-a-half soaring birds of more than 35 species; and about 20,000 records of 200,000 seabirds of over 40 species. It is also a dataset of enormous qualitative value, having been collected in a systematic and standardised way over many years.
The data come from the daily counts that take place throughout the autumn from Cazalla and El Algarrobo bird observatories near Tarifa, Andalucía. The seabird census is carried out from the Isla de Las Palomas in Tarifa, within The Strait of Gibraltar Natural Park. All is now included in the data logged for the corresponding eBird “Hotspots”. It makes for quite an interesting view on screen – we can’t imagine there are many Hotspots that have been allocated over 30,000 checklists!
Once the counts are completed, the data becomes public information, provided for free to eBird by the Andalucian Environmental Information Network (REDIAM) of the Ministry of the Environment and Spatial Planning of the Andalusian Government. The massive volume of data for the years in question was then incorporated into the eBird database by the eBird Spain team.
The importance of the data from these seasonal counts cannot be overemphasised. Without a doubt, it is a first-rate contribution not only to the eBird database, but to the knowledge of avian migration at a national and global level.
Seeing those huge numbers on screen can never be quite as mind-blowing as seeing the phenomenon in person! We feel super-privileged to be involved with such an epic project, and to see the results of the hard work from the most skilled, knowledgeable and loveliest bunch of volunteers and staff you could wish to meet.
Fancy contributing to science from a deckchair?! Contact Fundación Migres about upcoming volunteer opportunities.
Our Strait Birding & Cetaceans spring migration spectacular is coming soon, and there are still spaces available! Here´s a flavour of what happened last time…
“The clouds were low and moody, and the winds pretty strong, but the intrepid Black Kites had decided, “Stuff it! This will do!”. One by one, and then by the dozen, they started to appear out of the clouds, wings beating like crazy and some barely making land! We watched, hearts in mouths as two individuals struggled right in front of us, so close we could almost have dragged them in with a well-flung lasso!
There are no thermals over the sea, which is what makes crossing it so treacherous for soaring birds. Though barely metres from land, they were having to use the diagonal wind to gain lift, increasing the length of their journey many times. Then, after what seemed like an age they hit land and instantly found a thermal, taking them from a couple of metres above the sea to a couple of hundred metres above the land within seconds! We cheered them on with a massive amount of relief!
“Exhilarated, we headed down to the village for a coffee. But our break was not to be an uneventful one! Suddenly a break appeared between two large clouds over Punta Carnero and Gibraltar, effectively creating a sunlit channel of warm air which stretched right from the coast of Morocco to just above our heads!
This was the moment they – and we – had been waiting for! Necking our coffee we took up position by the sea wall as they began to arrive. Over the next hour or so we witnessed an immense river of raptors and storks arriving from Africa. Three hundred Black Kites, twenty Griffon Vultures, three hundred Short-toed Eagles, over a hundred Booted Eagles, 38 Black Storks, thirty or more Western Marsh Harriers and a sprinkling of Egyptian Vultures, Montagu´s Harriers, Eurasian Sparrowhawks and Lesser Kestrels poured over us in one of Nature´s most uplifting and vibrant spectacles. We abandoned all plans and ate our picnic right there, barely finding a quiet moment between migratory waves to grab a plate of food!”
This trip, running 28th March – 3rd April 2020, is not to be missed! Check out further information on our website here for your ringside seat to the greatest show on Earth…
When it comes to Ethical Birding Ecotours, it turns out we´re Top of the Pops!
We’re more than just a birding tour company. We care about the wildlife we showcase, the local communities we visit and the opportunities for education through exploration. That’s why we’re excited to announce that we’ve made it into the Top Ethical Birding Ecotours 2019 list!
This unique list is generated by a global community of travellers, bloggers, conservationists, tour guides, birders and ecotourism operators, and curated by Terra Incognita – a social enterprise seeking to promote the best examples of ethical ecotourism worldwide. We’re part of a group of over 70 incredible birding tours from across the globe.
First launched in 2018, the list has grown in its second year to include tours in 40 countries.
“With every new tour we discover, we’re amazed to see what operators are doing to have a positive impact on the planet through tourism,” said Dr Nick Askew of Terra Incognita. “Eventually we hope to showcase ethical tour experiences in every country worldwide.”
Tour operators on the list are doing everything from partnering with conservation charities and donating to conservation projects, to offsetting the carbon emissions generated by their business activities and encouraging their guests to do the same during their travels. Some are contributing to conservation research, while others are empowering local people through environmental education and capacity building, supporting future conservation ambassadors.
The list includes a transparent explanation of how all tours contribute to conservation, local communities and education and is open to reviews from guests who’ve participated in the tours.
“It’s exciting to discover ecotourism operators that see sustainability as a fundamental way of doing business, rather than just a marketing strategy or checklist”, said Kristi Foster of Terra Incognita.
“Rather than take away from a tour, guests can join in that creative, innovative process. These tours are experiences where everyone involved learns and grows”, she added.
The Top Ethical Birding Ecotours 2019 list was launched during the British Birdfair 2019 – an annual event for birdwatchers that supports BirdLife International.
Bird experiences highlighted range from Golden-collared Manakin leks in Panama, to reintroduced blue ducks in New Zealand, to searching for Uganda’s iconic Shoebill by canoe. You can even see the autumn Vulture migration across the Strait of Gibraltar, with as many as 2,300 birds recorded in a single hour.
With tours in 40 countries across six continents you can find inspiration to explore a new corner of the world or discover an ethical experience closer to home.
You can view the Ethical Birding Ecotours 2019 list at www.terra-incognita.travel and join a movement to create positive change for people and planet through travel.
We´re readying ourselves for our annual pilgrimage to UK Birdfair, and we hope to see you there! As you ready for the off and decide what to put in your butties, have a look at this profile of our good friends at Tarifa Ecocenter, participants in our #FlywayPromise, whose philosophy that “The fork is the most powerful tool to change the planet” chimes so strongly with our own…
In the Straits of Gibraltar we find ourselves at the epicentre of a great journey, that takes avian migrants over thousands of miles of landscapes and habitats where, irrespective of political borders, they must find food and safe passage to sustain them on their journey.
Our work over years for the RSPB, attempting to reverse the fortunes of UK, European and African farmland wildlife, has made us recognise the power of our own food choices and how it can affect the availability of habitat for these birds, and all the other wildlife whose lives depend on our decisions about how we manage land.
The Ecocenter is not just a superb vegetarian restaurant, it is a local hub for eco-consciousness. The organic produce shop and meeting spaces are a sociable place designed to encourage the exchange of ideas. Here you can partake in delicious, sustainably-sourced meals, much of the produce for which comes from their sister project, Molino de Guadalmesi – an organic farm, community centre, and eco-lodge situated in a beautifully-restored water mill.
“Sharing food connects people of all ages and backgrounds. Each meal gives you the opportunity to make a conscious decision about how you impact your health, your environment and our common future.”
Community member Johnny Azpilicueta is just back from a spot of global travelling and idea-sharing on sustainable living, so we grabbed the chance to catch up with him over a chickpea burger and a slurp of local organic IPA.
The thing that strikes me as we chat is the dual themes of connectivity and positive action that runs through everything they do – connecting people with where our food comes from, connecting them with the provenance and consequences of every food choice we make, connecting the food on our plate with the very field or animal it came from .
Johnny says: “I wonder what it would be like if people could see directly in the moment what the consequences of their choices are. Like, people don´t like animals and birds to be shot but if they are choosing unsustainable food they may as well be pulling the trigger themselves. I wonder what it would be like if every time they took a bite a bird fell from the sky in front of them, or every time they threw away a piece of plastic suddenly there was a dead dolphin right there next to them. What we want to do is to make people really see through all the complexity of their choices and help them make better ones that have better outcomes from the planet.”
Johnny is the driving force behind Tarifa´s hugely successful participation in World Clean up Day – one of the biggest civic movements of our time, where in 2018 a massive day of social environmental action saw a staggering 18 million people in 157 countries out picking up litter.
“ I find it is proving to be such a very unifying activity. Protecting the planet is full of complex issues but it seems that everyone has in common that they want their home to be clean, and it is something that can really bring people together in making positive action. It´s inspiring, it can lead to even bigger things.”
The concept of Flyway scale conservation is no stranger to Johnny either. “I have been in the Straits for 15 years and every time I look up and see these birds coming from all over Europe to cross to Africa, I feel connected. I feel this connection with Nature, I feel connected with how all the different parts of the world are connected and to the people who are trying to make these journeys too.
“What I think is that we have to allow these birds to cross like a pathway of organic farms all across the flyway, so they can eat healthy… Here we are making a Flyway Promise to support the kind of agriculture that is beneficial to these animals.”
Findings presented at the IPCC in October 2018 were striking and conclusive. While everyone talks about reducing electricity consumption and aviation, it seems that we are still ignoring the scientific findings that show beyond doubt that by far the best way of having a positive impact on our planet is to change what we eat. Currently 85% of the world´s farmed land produces just 18% of our calories. Loss of wildlife areas to agriculture is the leading cause of the current mass extinction of wildlife. This is the legacy of meat and dairy production, which has enormous environmental costs in terms of habitat loss, air and water pollution and carbon release.
In order to keep global temperature rise below 2ºC by 2020 we as global citizens will need to eat around nine times less red meat, five times less poultry and five times more legumes, vegetables, nuts and seeds.
On our trips we are working towards these changes by offering a higher proportion and better quality of vegetarian options on our dinner menus than ever before. Thanks to the bright idea of our friends at Huerta Grande Ecolodge to include “meat-free Mondays” in our trips, we are working with our accommodation and catering providers across the board to offer at least one meat-free day one very trip.
On selected tours, we visit the Molino de Guadalmesí for dinner, offering our guests a thought-provoking experience around food choice and how positive change can help our wildlife and the wider environment – not to mention be extremely tasty!
We want to make the choice to eat ethically an irresistible one! And thanks to the passion and talent of people like the folk at Molino de Guadalmesi and Tarifa Ecocenter, that doesn’t have to be difficult.
Come and see us in Marquee 1 Stand 28 at Birdfair this weekend, and come to the event´s Hobby Lecture Theatre, Sunday, 3.30pm to hear more about our #FlywayPromise and how we are striving to make ecotourism a genuine force for positive environmental change.
We all know that turbines and soaring birds don’t mix. So what is being done to help our avian nomads as they pass these whirring legions marching across the Estrecho Natural Park, one of the most important raptor migration bottlenecks in the world? We report on the Compensatory Measures Project, just one strand of the immensely important work carried out by our conservation partners, Fundación Migres.
As we round the corner of the coast road, in the hills high above Tarifa, most of our tour groups let out a gasp of awe at the stunning views of Morocco. This is often closely followed by a gasp of shock, as their gaze falls on the imposing ranks of wind turbines lining some of the coastal hillsides.
At just nine miles wide, here the Strait of Gibraltar is at its narrowest point between Europe and Africa, making it the chosen crossing point for over 300 million migratory birds, journeying between these continents twice a year.
A humungous sixty percent of Europe’s raptor population passes through here, as well as virtually its entire population of White Storks. Swifts also cross here in staggering numbers, with more than 400,000 passing through the area during peak times. This migratory spectacle is one of the most uplifting, life-affirming natural events we have ever seen, and simply has to be experienced to be believed.
With some 350 different species recorded, the list of birds in the area is extensive. At migration times there are Honey Buzzards, Western Ospreys, Red-rumped and Barn Swallows, Sand and House Martins, Pallid, Common and Alpine Swifts, Common and Great Spotted Cuckoos, races of Yellow Wagtail, Western Bonelli’s Warblers, Common and Iberian Chiffchaffs, Golden Orioles and Turtle Doves amongst many others.
At any time of year, birds in the area include Crag Martins, Blue Rock Thrushes, Crested and Thekla Larks, Lesser Kestrels, Tawny, Little and sometimes Eagle Owls. A wide range of nesting raptors, including Bonelli’s Eagles, Short-toed Eagles, Common Kestrels and Peregrine Falcons are common in the area. Around Tarifa there are colonies of Griffon and Egyptian vultures, the most southerly in the Iberian peninsula, with 70+ pairs of Griffon Vultures and six pairs of Egyptian Vultures breeding in 2017.
So how did these feathered millions end up running the gauntlet of the wind farms, adding to the perils they already face?
Back in 1993, when the area was still military land, the original two windfarms were commissioned, approved and built. The 20 MW Planta Eólica del Sur (PESUR) project and the 10 MW Energía Eólica del Estrecho (EEE) farm totalled 269 turbines. They were straight away mired in controversy, with local conservation groups and independent experts presenting evidence in 1994 of high avian death tolls(1). The corpses of 13 different species were allegedly found at the wind farms, either killed on impact or by electrocution on power cables, including an Eagle Owl, White Storks and Lesser Kestrels.
A random corpse count of Griffon Vultures stood at around 30, with some apparently decapitated by the blades. Counter-claims at the time by the wind company’s managing directors suggested that the yearly death count was never higher than twelve birds in total, and others presented figures as low as two birds.
In some cases it was alleged that no real impact study regarding the birds was ever carried out. It was even alleged that, while risk assessments were carried out based on presence of resident birds, the experts simply ‘forgot’ to account for the hundreds of thousands of migrating soaring birds that pass through twice a year!
Spain had (and still has) an ambitious plan for alternative energy generation, and the Tarifa area was to be its spearhead. Development of a proposed 2000+ turbines in the area were to provide a sizeable chunk of Spain’s 20% renewable energy target by 2020.
One can only imagine what it would have been like to be a fly on the wall in the many meetings that must have taken place, leading up to the declaration of the area as a Natural Park in 2003. With the area now protected, and acknowledged as an Important Bird Area by Birdlife International, extensive study and intensive mitigation work would be needed to reduce the negative effects of existing farms and prevent the creation of new ones in high-risk areas.
Enter Fundación Migres. This private non-profit organisation had been monitoring the area’s extraordinary migration event with daily counts during peak times since 1997.
In 2003, the companies whose memberships form the Tarifa Wind Power Association (AET) signed agreements with Fundación Migres to work on the Compensatory Measures Project for La Janda Windfarms, dramatically expanding their remit.
During the seventeen year project, their task was to find ways to reduce bird mortality in the windfarms, find out the effect of the farms on local raptor populations, and establish recovery programmes for more affected species, as well as raising awareness locally about environmental conservation and renewable energy.
The high-quality, independent science they have generated since their inception has added considerably to the world’s knowledge on wind farms and their effects on birds. It is helping develop better protocols for Environmental Impact Assessments (EIA) and mitigation measures to reduce turbine collisions.
Their work has generated both disturbing and promising results. A three-year study of 20 operational wind farms took place between 2005 and 2008, as the 323 turbines gradually came online(2). Over the study period, the research team found 596 dead birds – a devastating 1.33 birds per turbine per year, which is among the highest rates of wind farm mortality ever published. 36% of the dead were raptors and included 23 Common Kestrels, 13 Lesser Kestrels and 16 Short-toed Eagles.
By far the worst affected bird was the Griffon Vulture, with 138 found dead during the course of the study. Other studies suggest that most birds of prey can detect and actively avoid turbines without too much problem(3), but alas for the Griffon Vulture, for all its aerial prowess, agility is not one of its strong points. The bird relies on air currents and thermals to travel and has relatively weak flight, making evasive manoeuvres difficult.
All of these high-mortality wind farms had had EIAs carried out according to accepted methodology, had been accepted as low-risk areas, and had been licensed according to the law. The way raptors use the air currents and topography of an area is complex. It seemed site-scale EIAs based on bird abundance did not account for this, so could not adequately predict the threat level of proposed turbines.
However, interestingly, the study also found that the vast majority of these deaths could be attributed to a very small number of turbines. A new study was undertaken(4) – what if, by controlling function of these high-risk turbines, bird mortality could be reduced?
During 2006, body counts on 13 windfarms with 296 turbines had illustrated that most of the deaths were being caused by just ten turbines, distributed amongst six windfarms.
During 2008–2009, the team implemented a selective stopping program – when Vultures were observed near these deadliest turbines they were simply turned off till the threat had passed. Encouragingly, the Vulture mortality rate was reduced by 50% with only these ten turbines involved. The consequent reduction in total energy production for the wind farms was just 0.07% per year, a small price to pay.
This successful strategy was expanded to other high-risk turbines. When a high number of raptors are passing through, or individual birds are in danger – especially Griffon Vultures or the Critically Endangered Egyptian Vulture – the turbines are simply turned off.
With Migres-trained wind farm ‘watchmen’ on high alert, the whole shutdown process – from spotting a risk, to phoning it in, to stopping the relevant turbine – takes less than two minutes. The annual mortality – previously exceeding 200 vultures – has been reduced by 60% across the whole area(4). The accidents happen mostly during the autumn migration period when young birds – both resident and from all over Europe – are passing through the area. Though this is still a horrible price to pay for clean energy, this level of loss is at least thought to be sustainable from a population size point of view.
The process is far from perfect. A locally-breeding Egyptian Vulture was killed by a turbine last year, and two the year before. A drifting radio-tagged Lesser Spotted Eagle also hit a turbine, but seemingly recovered its wits and moved on, after sitting dazed in one spot for two days. We ourselves have been devastated to witness a majestic Honey Buzzard, hanging on an air current, lose control for just a brief second and get sucked backwards into the blades. And this is without even touching on the as yet unmitigated effects the turbines have on bats and other wildlife.
The end of the windfarm cooperation project in 2020 is fast approaching, putting the future of the turbine-stopping measures in doubt. With funding for Fundación Migres in decline, also at stake is one of the greatest sustained efforts for monitoring migratory birds in Europe, not to mention the invaluable research they generate.
It can be hard to believe that wind farm development was ever given the go-ahead in such a key area for the birds of the East Atlantic flyway. But it’s important not to forget the bigger picture. Many more birds are killed by traffic, power lines, radio and television towers, glass windows, and due to human activities such as poisoning and illegal shooting, not to mention habitat destruction.
Badly located as they are, the ever-spinning blades of the Straits supply around 20% of Andalusia’s power. Like all locally-damaging ‘renewable energy’ sources, they are there because of our insatiable appetite for consumption – of fossil fuels, of meat, of stuff we just don’t need. As the planet warms, ecosystems are disrupted and the Sahara creeps ever larger. For the millions of avian nomads that pass the turbines unharmed, the biggest peril is whether they still have breeding and wintering habitat to go to.

It´s hard to pick a favourite time of year here in the Straits, at the very epicentre of migration , the midway point of a million avian journeys. At the moment we’re crazy about Spring!
We are midway into Spring migration, when every day yields new – often unexpected – treasures. There´s always a feeling of anticipation when you step outside – the air is fresh, the short heavy showers and the bright sun bring the hillsides to life with a riot of colourful wildflowers.
The Black Kites as ever began determinedly pouring through in late February. It seems nothing can stop these dark, determined bad-ass birds – they were recorded crossing the Straits in a Force 8 a few days ago! As the season progresses, their numbers are swelled by increasing numbers of Short-toed Eagles, Egyptian Vultures, Sparrowhawks, Booted Eagles, and Montagu’s Harriers – often exhausted, always spectacular.
During the challenging sea crossing of a windy Spring day, there is many a captivating individual struggle to watch unfold. One moment of drama saw us glued to our scopes at the peril of a small male Sparrowhawk, flying full tilt towards the coast pursued by seven or more Yellow-legged Gulls trying to knock it into the sea. Twice they clumped it from above so hard it clipped the waves. But twice it flipped over, talons bared, and grappled a Gull into the sea into return. We couldn´t see how it was going to survive this persistent mobbing but the plucky little fellow made it to the coast, and we cheered!
The coast west of Tarifa is quite developed, but blessed with many unassuming areas of urban parkland. It´s fantastic to stroll through the park at La Linea on a Spring morning after westerly winds, to find the tamarisks and olive trees dripping with Common Whitethroats, Subalpine and Western Bonelli´s Warblers, while Northern Wheatears and Common Redstarts forage on the ground amongst children playing on the swings and people throwing balls for their dogs.
In the coastal scrub of Los Alcornacales Natural Park, every day brings a new wave. Early on, the Great Spotted Cuckoos flush through on their way to find their corvid surrogate chick-rearers. One day there are suddenly stacks of Tawny Pipits, then the next day Black-eared Wheatears and Woodchat Shrikes adorn every fence and bush as they decide whether to stay local or reach a step further.
Not long after that, the hills are alive with the sound of the squelchy song of Common Nightingales. Amongst the constant ebb and flow of Barn Swallows, suddenly there are Red-rumped Swallows too, and on an afternoon stroll around the coastal valleys you´ll find yourself surrounded by sudden swarms of feeding Pallid and Common Swifts.
A recent extended period of strong easterlies, generated by a low pressure system over Morocco and the Middle East, brought some surprises this year with Lesser and Greater Spotted Eagles crossing the Straits and a number of Pallid Harriers recorded in Spain. We also yet again found a Yellow-browed Warbler at our eco-lodge base, Huerta Grande, this time apparently heading north on its parallel migratory trajectory!
It´s hard to beat that uplifting moment when you become aware of a distant excited chirruping, which gradually becomes louder until the air around you is full of European Bee-eaters, travelling in colourful, exuberant family groups. They always give the impression that they´re on their way to a party!
And there is so much more to come! The first Honey Buzzards have been recorded and we wait in anticipation of their spectacular passage numbering over 100,000 birds. Soon the Golden Orioles will sweeten the air, Rufous Scrub Robin will brighten the scrub and the cryptic beauty of the Red-necked Nightjar will touch the eye of those patient enough to quietly look.
It´s so good here! And it´s decided, Spring is definitely our favourite season! Well, until Summer that is!
At the gateway between Europe and Africa, there is biodiversity galore! Avian migration is the most visible and celebrated, and we spend a lot of our time looking up. But to never look down would be to miss out on so much, including some of the best moth-trapping opportunities in Europe. That´s why, with the help of acclaimed international moth expert Dave Grundy, we´ll be running a trip in May 2019 to look more closely at the gorgeous local nocturnal Lepidoptera under our very noses!
We caught up with Dave to ask him about all things moth-y, and more!
So Dave, what drew you to the Straits? Why would you recommend it to British moth-ers?
The Straits is just an amazing place! There are so many moths and a higher diversity all year round, and it’s all in brilliant scenery with great hospitality from local Andalusian people!
I first started coming here simply to extend the mothing season. I was fed up of opening traps in the cold to find none, or maybe one moth huddled in the corner of the trap, so I headed south, to look forward to opening a trap and finding 60 species in it!
I got hooked, really – it is a real biodiversity hotspot at the crossroads of two continents, the far south of Spain in Europe and the far north of Morocco in Africa. The geology is diverse due to the collision of two continents in geological time and this leads to a diversity of fauna and flora and of course this includes a very rich fauna of moths.
The mothing sites are great and from a totally different biogeographic area – trapping Mediterranean olive scrub and cork oak forest in an area where new moth species are likely to be discovered! What’s not to get excited about?
We know you´re often to be found trapping at Europe´s most southerly point at Fundacion Migrés coastal HQ. And also enjoying a pizza at top veggie restaurant Tarifa Ecocenter! Any other favourite hangouts in the area?
I love to stay at Huerta Grande up in the hills above Tarifa. From there you can step into both the coastal Natural Park of the Straits with its olive scrub and coastal habitats and inland to Los Alcornocales Natural Park, which is on inland hills cloaked in humid cork oak woodland.
There´s birds to enjoy too, for those that like that sort of thing! The Straits is probably most famous for its twice-yearly raptor migration event during which 250,000 soaring birds pour across the sea. Plus there´s loads of nice resident birds in local coastal, wetland and woodland habitats. You get things like Crested Tit and Short-toed Treecreeper just hanging around the log cabins at Huerta Grande!
We remember coming to inspect a trap with you and you showed us our first Giant Peacock Moth. Europe´s biggest moth! It was mega! What are some of the other cool species you’ve trapped in Andalusía?
There´s so many! Goldwing, Passenger, Alchymist, Latin, Pale Shoulder, Striped Hawk, Lydd Beauty, Four-spotted, Eutelia adulatrix, Porter’s Rustic and Speckled Footman to name just a few.
I don´t really have a favourite but I do like Lemonia philopalus, a lot! Why? – is more difficult to say – big and furry and stripy with amazing wing and antennae patterns. And also crazily it needs heavy rain to come out – and this is because it pupates in the soil and needs the soil softened by rain to emerge!
For the newcomer, how does mothing with a local expert help?
Mothing in Spain is difficult, if not impossible for non-local people who don´t at least have mothing friends here. You need a moth-trapping licence, which is expensive and really difficult to fill in – in Spanish, of course!
Best to hook up with somebody who has all the kit and permissions, so you don´t have to worry about it. I have the all the paperwork and licences you need for trapping. I have the permissions off local landowners to trap in the area. I bring lots of traps here from Britain in my van – so when people come mothing with me they have access to five or more moth traps every night to see what is inside – and no need to bring your own trap! If you fly out here, you would be lucky to squeeze one trap into your suitcase.
Over the ten years I´ve been coming here I´ve been lucky enough to make some great friends in the local mothing community – a group I´m working hard to build! I´ve got lots of gen now on where the good sites are for moths. It´s been fascinating building up experience trapping in olive groves, or cork oak forests or sand dunes by the sea. There are so many special moths to see! I feel I can now say I know the moths of the area as well as anyone. Which is handy for people on the trip, as the main moth books are in Spanish, and many of the moths we´ll see only have a scientific name!
What’s the Spanish word for moth?
The fancy way of saying it is mariposa nocturna which of course translates as “night butterfly”. However I´m trying to bring the word polilla into popular use. It´s a Spanish word for moth, but it actually has negative connotations – it´s usually used to describe the kind of critters that munch their way through your clothes! It makes people laugh when you describe yourself as a moth-studier by using the word polillero, which is why I like it!
Are you excited about running our 2019 Mothing the Straits trip? What does it have in store for the group?
Of course I am! I´ve run loads of successful field courses before, but an actual moth-ing holiday?! As far as I know it´s a first!
Every night we´ll have one or more traps within walking distance of the log cabins at Huerta Grande, plus we will head out into nearby habitats each night to set up another five traps. Each night we will do this in very different habitats within a few miles of our base.
Then we come back for a lovely three course meal of typical local food with plenty of wine and beer!
Then every morning we will head back out to check the traps and this will probably take us the whole morning including photographing the most exciting moths. After that there´s time for picnic lunch, siesta, local exploration, whatever you like, before we set off again in the evening!
The trip actually also coincides with the area´s massive raptor migration. Tens of thousands of Honey Buzzards will be crossing the Straits daily, alongside other raptors like Short-toed and Booted Eagles. I know some of the people that have already booked on my trip are also extending their stay a bit to watch migrating raptors and do some excellent local birding with you two!
Thanks Dave! Sounds amazing! So tell us, where can people find out more about this ground-breaking moth-trapping holiday?
There´s full details on the website tour page, and you can have a look at my profile there too! There´s not many places left though, so don´t hang about!
4 Days. 5 Swift Species. 135 bird species. 13 Spain ticks. 5 world Lifers. And aside from the numbers, this trip offered just a superb weekend of birding in Andalusia with our guest John, in wetland, farmland, woodland and mountain habitats, giving fantastic views of all the wealth of breeding bird species the area has to offer!
White-rumped, Little and Alpine Swifts shone out from the astonishing masses of Pallid and Common Swifts, day-roosting Red-necked Nightjars and Tawny Owls caused us much hushed excitement, and we enjoyed encountering all the other hard-to-see specialities of the area, such as Rufous Bushchat, Common Bulbul, Red-knobbed Coot, White-headed Duck, Red-crested Pochard, Audouin´s Gull, Black-eared Wheatear and Northern Bald Ibis.
Butterflies and reptiles were also super-abundant in the perfect weather, as was tasty food, cold beer and good company! This was to be a swift weekend to remember!
On the farmlands of La Janda, the air was absolutely filled with enormous flocks of several thousand feeding Pallid and Common Swifts, with a mass emergence of Red-veined Darters making up the larger part of their airborne feast. As we enjoyed our first picnic lunch, we were joined by a Great Spotted Cuckoo, while a Short-toed Eagle, a Western Marsh Harrier and several early-migrating Black Kites drifted overhead.
Moving to a higher area of the farm we stopped at a patch of bushes. A quick search with our optics in the undergrowth and the leaf litter and we were looking at a gorgeous Red-necked Nightjar! We looked on in hushed awe, taking great care not to disturb this beautiful bird as it rested.
We enjoyed the brilliant value Egret colony with Little and Cattle Egrets nearly ready to fledge, pootling around the trees like little arboreal chickens. A single Black-crowned Night Heron also caught our eye. We also had views of Sand Martins, singing Turtle Doves, and over fifty European Bee-eaters, as well as Glossy Ibis, Eurasian Spoonbill, Green and Wood Sandpiper amongst others.
To celebrate a great day, we took John for a night out in Tarifa! Here we added Common Bulbul to John´s Spain list and enjoyed the antics of the town´s Lesser Kestrel colony currently full of newly fledged youngsters.
We enjoyed superb Spanish/Mediterranean cuisine, made from locally sourced organic ingredients at Tarifa Ecocenter, before trying a pint or two of ale from the local microbrewery!
Wandering through a local Cork Oak and Wild Olive dehesa, beautifully cool in the shade, we found many newly-fledged birds, accompanied by their parents. These included Corn Buntings, Woodchat Shrikes, Common Nightingales and Sardinian Warblers. There were also large numbers of Spotted Flycatchers, part of an early passage south.
Pausing at a site that looked good for warblers, we tuned into a song of short, melancholy phrases – a Rufous Bushchat was singing! This was our main target for the morning, and with a bit of patience and careful following of the sounds we managed to get astonishing views of this glamorous Chat. Another for the Spain list…
While Niki & Simon prepared a lunch of delicious local salads, olives, meats and cheeses – not to mention a nice cold Cruzcampo beer – John enjoyed watching Black-eared Wheatears, Thekla and Crested Larks, Crag Martins, Short-toed Eagles, Griffon Vultures, Northern Ravens and a Peregrine Falcon overhead, and a couple of Monarch butterflies, at a mountainside site known as La Peña.
A fantastic afternoon´s birding at the disused saltpans of Barbate awaited! A great selection of roosting seabirds including Sandwich Terns, Audouin´s, Slender-billed and Mediterranean Gulls greeted us when we arrived. Kentish Plovers, Pied Avocets and Common Redshanks were super-numerous, and after a little searching we found several Collared Pratincoles and a Eurasian Stone Curlew. Short-toed Larks and Iberian Yellow Wagtails were there, and a fab Little Owl watched us from the fence. We enjoyed watching fearless, noisy Little Terns seeing off marauding Yellow-legged Gulls from their nesting colony.
A slightly earlier start one day gave us time to enjoy the avian wonders of the Bay of Cadiz, and the eastern side of Doñana National Park! En route, mooching peacefully about on dew-covered grass, we found five brilliant and quirky Northern Bald Ibis! One of the ten most endangered birds in the world, these charismatic individuals are doing well here in Andalusia, several generations in to a successful reintroduction project.
At a harbourfront complex on the Bay of Cadiz, we stopped for a coffee and were greeted by a swirling mass of Common Swifts. Amongst the screaming we heard a giggle, and sure enough there was a Little Swift! As we sat down with a cuppa we counted at least six amongst the mélé, allaying our fears that the colony had suffered a wipeout during March´s storms.
At the Bonanza saltpans, copious microfauna in the traditionally-harvested salt pans made them glow an extraordinary iridescent pink. The pans were teeming with Slender-billed Gulls, Greater Flamingoes, Kentish Plover, Common Redshank and Pied Avocet. A couple of Dunlin signalled that here too, the southbound migration had already begun. Little Terns, a Gull-billed Tern and an Audouin´s Gull were also seen, as well as Iberian Yellow Wagtails.
Some unassuming roadside irrigation ponds in Colorado made for some simply fantastic birding. There were several White-headed Ducks and Red-crested Pochards with ducklings, Ferruginous Duck as well as Little Bittern, Common Waxbill, Black-crowned Night Heron, Common Kingfisher and Great Reed Warbler. And there, right at the day´s end, skulking in the shade, was a single Red-knobbed Coot, knobs glowing in the occasional shaft of sunlight! Another much sought-after Spain tick for John, and his third Lifer of the day!
In the shade of Cork Oaks, Laurels and conifers at a local huerta we enjoyed the sights and sounds of Short-toed Treecreepers, Crested Tits, Iberian Chiffchaffs and Firecrests while Speckled Woods and Purple Hairstreaks flitted through the canopy. And, after some careful peering up through branches, we managed to find a day-roosting Tawny Owl! A superb bird to see in daylight at the best of times, made all the sweeter for being a Spain tick for John.
And for our grand finale, at a reservoir site in the Alcornacales Natural Park, we achieved extraordinary views of a pair of White-rumped Swifts! A joyous little bird, with quite a different jizz to its larger cousins. We spent some time enjoying their comings and goings and were further rewarded when John picked out an Alpine Swift amongst the throng, completing our Swift Grand Slam!
Then all too soon it was time to take John to his flight at Gibraltar airport. On the way we discussed our trip and found that, as well as seeing all five Swift species and a wealth of other fantastic wildlife, we had also smashed John’s target and got his Spain list to 254! An enjoyable and memorable weekend all round – thanks John!
If you´re looking to escape the summer birding lull in the UK, this is the trip for you! Birding the Straits of Gibraltar at this time gives you access to a wealth of breeding species that can´t be seen anywhere else in Europe! Take a look at the Swift Weekender 2018 trip report to see what we mean! Join us in 2019 for a Swift Weekender…
