Saying “Később találkozunk!” to the Honey Buzzards!

This week, along with our friends and conservation partners at Fundación Migres, we counted just a handful of European Honey Buzzards crossing The Straits of Gibraltar on their migratory journey.  Picked out from amongst thousands of Booted and Short-toed Eagles, Eurasian Sparrowhawks, Black Storks and Griffon Vultures, each one of these gorgeous birds merited close attention to their detailed and variable plumage.  Not least because at this point of the year, we never know which one will be the last we’ll see until Spring!

“Honey Season” is definitely drawing to a close and these numbers are very different to those we observed during the peak in late August / early September, when we counted over 47,000 birds crossing in just one week!

These tail-enders are the last few of the 85,000 or so that will have passed through here this autumn.  This is more than the breeding population of western Europe, so it’s clear that something interesting is going on!

Spring counts of birds heading north across The Straits yield far smaller numbers – typically around 15-17,000.

Ornithologists have speculated for some time about the reason for the discrepancy in numbers.  It seems – as you might imagine – that the populations that breed in north and western Europe migrate back and forth along the route that brings them through here.  However in autumn, their numbers are augmented by their eastern cousins.

Research published in 2019 used satellite telemetry to follow a single adult male European Honey Buzzard, tagged in Hungary, over three years of its life.  It supports the theory that many of these eastern birds follow an incredible anti-clockwise loop migration, spanning vast areas of Europe, to travel between their breeding and wintering grounds.

Once the breeding season is done for another year, the priority for these nomads is understandably getting to their wintering grounds as safely as possible.  Heading to Africa via The Straits of Gibraltar is definitely the long way round, adding over 2,300 km to the trip compared to a direct route.  Each autumn, the male in the study (let’s call him István!) covered an astounding 7,046km from Hungary to his favoured wintering site in North Cameroon in around 43 days.

The study also measured how much the bird was compensating for crosswinds – in other words, actively choosing his route.  It revealed he worked extremely hard to stay en route to The Straits, only drifting passively for about 10% of his journey across Europe.

The advantage of this mammoth detour is to allow István to avoid the risks associated with trying to cover many miles of thermal-less water crossing the Central Mediterranean.  Our 14 km sea crossing at Tarifa is nothing to these bad-ass flyers!  Their compact structure, intermediate between harriers (Circus spp) and true buzzards (Buteo spp) lends itself to powered flying and leaves them somewhat less reliant on thermals than longer-winged raptors.  It’s no wonder that we see them crossing in seemingly treacherous conditions, powering out across The Straits in large groups while longer-winged birds like Short-toed Eagles cling nervously to the coastal hills!

Once safely over the sea and into Africa, István spent relatively little effort compensating for wind direction while crossing The Sahara, spending over half the crossing simply drifting effortlessly over this perilous wasteland.  Thanks to this and other studies, we are starting to understand that these incredible birds plan their routes not only to avoid threats but also to connect with anticipated weather conditions, such as helpful prevailing winds. Totally amazing!

István took his time on his way south to his African R&R spot. Of those 43 days, 12 of them were spent on chill-out stops!  Spring however, is a different matter altogether.  Speed is everything, and the race is on to return home as fast as possible and secure the most optimal breeding site.

This leads István and many like him to make a beeline (sorry!) for the breeding grounds, foregoing the relative safety of The Straits of Gibraltar and taking their chances on longer sea crossings.  He flew all the way back to Hungary in just 23 days, resting for only six and slicing almost 1,500 km off his journey, crossing the Mediterranean via Tunisia’s Cap Bon Peninsula, Sicily, Italy and Albania.

Meanwhile here in The Straits, we would have been seeing almost exclusively those birds heading to north and west Europe – including France, the Netherlands, and even the UK.

For young birds though, the picture is very different.  These risk-averse autumn routes are learned in later life, by following experienced adult birds.  In its first year, a Honey Buzzard is effectively abandoned by its parents, which leave the breeding grounds on average 1-2 weeks earlier.  It can only follow its innate sense of direction, which leads it SSW, to launch itself at whatever water body or desert it finds in its way!  Only the strong – and lucky – survive.  One in three young Honey Buzzards will die on their first migration while crossing the Sahara.  The area of Africa where they end up wintering – and to which they will eventually become site-faithful – is largely determined by winds and chance.

After such a large investment in rearing the young Honey, this seems like some pretty harsh parental treatment!  However, as always, everything makes sense in the light of evolution.  Every day adults delay their own journey, and every day they would lose en route accompanying slower, less-skilled juveniles decreases their own survival chances.  This more supportive parental behaviour would soon fail as a strategy.  Evolution has moulded  this behaviour – effectively sacrificing one in three young birds who will die on migration without guidance – to ensure that the successful adult optimises its chance of survival and lives to breed another season.

This absentee parenting strategy has certainly worked for István!  He was first tagged as an adult in 2014, and is still going strong.  On 7 September this year – amongst 9,499 other individuals – we observed a tagged bird crossing The Straits, who we subsequently learned had travelled to us from Hungary!  I hope it was István, and I’ll be thinking of him and his epic journey ahead.

Safe travel to The Straits is back!

As COVID-19 remains under control in Spain and cases continue to dwindle, we are extremely pleased that we can now begin to safely deliver our day trips and tours!  With the announcement of Europe-wide “air bridges” on 4 July, international travel to Spain from many countries is now available with stringent health precautions en route but no self-quarantine measures at either end of the trip.

This spring in The Straits of Gibraltar, one of the world’s most breath-taking migratory spectacles passed by almost unobserved.  But whilst we were all sequestered away, Nature carried on regardless, and now these same birds that passed by so spectacularly unseen are preparing to make their journey to their sub-Saharan wintering grounds, new offspring in tow!

We’re thrilled that, this autumn, we’ll be able bring you right to your front row seats at Nature’s greatest show either for a day or bespoke trip, or as part of a scheduled departure tour.

The Strait of Gibraltar is the point at which Africa and Europe are at their closest, and is the epicentre for one of the world’s most spectacular bird migrations.  Every year, millions of birds make the 14 km sea crossing, making use of uplifts and thermals rising off the Rock of Gibraltar and the stunning Moroccan peak of Jebel Musa. An estimated 300,000 raptors and other soaring birds pass over this rugged terrain during autumn, as well as untold thousands of other journeying passerines and seabirds.

As well as the star attraction, a boat trip into the Straits itself will let you get close and personal with our resident cetacean species – Common, Bottlenose and Striped Dolphins and Long-finned Pilot Whale.  Even migrating Fin, Sperm Whales and Orca are possible here.

There’s plenty more to explore among the area’s superb habitats, which include salt pans, intertidal areas, freshwater wetlands, low intensity farmland, Mediterranean scrub, precipitous rock faces and the woodlands of Los Alcornocales Natural Park, Europe’s largest Cork Oak forest.  The diversity and wealth of avian and other wildlife in this beautifully unspoilt area of Spain really is astounding!

Couple this with tranquil accommodation in an eco-lodge at the edge of the Natural Park itself, the chance to enjoy the picturesque streets and Moorish fortifications of the Old Town of Tarifa, and of course the chance to sample some of Andalucía’s best local sustainably-produced food and wine, and you really do have a trip that’s Strait-up fantastic!

Over 20,000 Moths in one night!!

Dave Grundy – leading authority on Andalusian moths and expert guide for Inglorious Bustards’ Mothing The Straits holiday – tells us about this phenomenal eruption of Gypsy Moths!

So, what’s the most moths you’ve ever had in your moth trap? And what’s the most of one species? I’ve heard talk of 750 Large Yellow Underwings (Noctua pronuba) in one trap in the UK and maybe as many as 2,000 total moths in the trap of all species?

106218498_4007177435990119_8415083496723280601_o

Well this month I have had an interesting time with numbers of moths of one species in particular – the Gypsy Moth (Lymantria dispar). It causes economic damage to forestry in North America – where it was introduced – and also on a local level in Europe.

There has been a population explosion in The Straits of Gibraltar area of Andalucía, from Algeciras to Tarifa along the coast and up to about 8 kilometres inland. Beyond that, the species is flying but does not appear to be in any large numbers (we saw only 36 across 6 traps near San Roque on 27th June).

I was first aware of the larvae back on 17th May 2020 when I recorded at least 10 in my notebook when trapping at Huerta Grande, Pelayo, Andalucía, with José Manuel Gaona Ríos.  We then went to Bosque de Niebla trapping on 5th June 2020 with Rafael Rodriguez Pino when my notebook just says “millions of caterpillars stripping the oak trees of all leaves”. This must have a massive effect on the ecology of other insect species dependent on the leaves and also on bird life and others dependent on the trees and insects.

But is this a phenomenon to be celebrated as a marvel of nature or to be horrified about?  Could climate change be a factor? This event, which occurs cyclically every few years, is now occurring more and more often, coinciding with periods of drought.  I don’t know what the answer is. However, I am definitely not a fan of attempts to eradicate on a large scale as this causes damage to so much other wildlife at the same time.

Next I saw my first ever male Gypsy Moth in Spain on 6th June 2020 – what a stunning creature when fresh and new! This was at Centro Internacional de Migración de Aves (CIMA), Tarifa, where we do not have the oak tree foodplants for the larvae to feed on, but they disperse here looking for females, which struggle to fly far from their original location. 

106411999_4007152662659263_2207258127156018320_o

Numbers then began to increase with 325 recorded on 15th June 2020 and 673 on 17th June and then a stunning estimated 5,000 to one trap on 19th June in calmer weather – this was ridiculous! An estimated 4,940 came to one trap on 20th June and then numbers have been up and down since, with more on calm nights and less on windy nights.

My peak count was on 28th June 2020 when I estimated 24,850 between 5 traps and 10,900 in just one of those traps! Moth recording becomes a nightmare and I even had to wear my COVID mask because of all the scales in the air! I believe and hope we are now near the peak in numbers, so I can return to normal moth-trapping soon!

But yet, how spectacular! At nearby sights just north of Tarifa I have recorded over 5,000 at La Peña and over 1800 at Punta Paloma. And to put the numbers into perspective I have now recorded since February in Spain a total of over 650 species and over 106,000 moths, but of those 60,690 have been of Gypsy Moth adult males since 6th June 2020!

Breakfast with Vultures!

Going out to a restaurant isn’t something we’ve been able to do a lot of recently, but today we were thrilled to be invited to an eatery with a difference!  The menu didn’t really appeal – we’re all for trying new things but offal, rotten eggs and cow dung are a bit too avant-garde even for our tastes!  The thrill of the invite came purely from the chance to rub shoulders with the celebrity guests…

For this beastly bistro has been set up with one purpose in mind – the conservation of the Endangered Egyptian Vulture – or Alimoche as they are known in Spain.

DSC00314

With its starkly-contrasting wing pattern, wedge-shaped tail and yolk-coloured face, this gorgeous bird must surely be one of the most eye-catching scavengers in the world.  It is both sensitive and intelligent, using pebbles to break eggs, sticks to wind wool, and staying faithful to partners and nest sites over long periods. Incredible travellers, migrating birds can cover over 300 miles in a single day along the East Atlantic Flyway, until they reach the southern edge of the Sahara, as much as 3400 miles from their summer home.

Sadly, the same old story of human destruction applies to this species as to many others. Their numbers have declined dramatically – in Europe, over 50% have been lost in the last three generations. Throughout their nomadic year they face many dangers.  The disastrous effects of the terrible twins threats of habitat destruction and agricultural change are exacerbated by lead and pesticide accumulation, persecution, collisions with power lines, intentional and accidental poisoning.

Around our base, in the Campo de Gibraltar and La Janda area, we are lucky enough to host a small breeding population of this stunning bird – five of the remaining 1400 pairs in Europe.

But here they face the peril of our local windfarms.  Despite the fantastically successful work of our partners at Fundación Migres to reduce raptor collisions, in recent years there have been some strikes involving Egyptians from the local population.  The presence of ornithologist “spotters” on the farms – such a successful strategy for protecting Griffon Vultures and other species – is simply not enough for these birds.  The deaths were few, but with such a tiny population, any such losses are desperately significant, and pose a risk to the birds’ future in the area. It was clear a new approach was needed.

In 2018, Fundación Migres started piloting the creation of supplementary feeding points near to Egyptian Vulture territories. The idea was that if the birds could find “easy” food at strategic points near their nests, they would no longer take risks foraging near turbines.  Turbine strikes of foraging adults would be reduced or hopefully even eliminated.

Suitable sites for supplementary feeding have to be well-located – close to one or more Egyptian Vulture territories, with a clear route to the nest that avoids windfarms. They have to be easily accessible for the feeding team, yet be quiet, safe places, away from human disturbance. Experts at Fundación Migres identified several such sites and began feeding, eventually narrowing their efforts down to the two most successful locations.

Unlike Griffon Vultures, which have evolved to work together to rip open and devour large carrion items, Egyptian Vultures love to pick up the scraps!  For this reason, they get given the piltracos – small items of meat waste and offal collected from local butchers in the Tarifa area.

In one of life’s rare win-win situations, the butchers also save the money they would otherwise pay for a waste disposal service. The meat is transferred in authorized containers to the supplementary feeding points, where it is put out four times a week.

So this morning, we stood in a secluded field while our friend and colleague Alejandro dished up 90kg of waste meat, guts, bones and other unspeakable titbits, accompanied by soothing background music from Cirl Buntings, Turtle Doves and Common Nightingales!

As well as the main feast of meat scraps, the team also puts out attractive side dishes like eggs and cow dung! For an Egyptian Vulture, these accompaniments are simply to die for – they are rich in the carotene pigments they need to give them that gorgeous yolky-yellow face. 

To measure the success of the project, the sites are checked daily and activity is also monitored using camera-traps.  Many of the birds are tagged or ringed, so a detailed picture can be built up of which individuals or pairs come to the sites and how long they spend there.

At the same time, in the wind farms, the “spotters” collect information on any birds that fly nearby.  This means that the team can make a direct comparison between days when food is laid out or not, to see if it reduces the birds’ presence in or around the windfarms.

Preliminary results of the pilot are very promising. Since the trial began, there have been no deaths of local birds on the windfarms.  The supplementary feeding points have significantly reduced the number of birds recorded near wind farms, massively reducing the risk of collision. This is especially important while they have chicks are in the nest, and adult foraging is particularly intense.

The fringe benefits of the project have also been impressive!  It seems word has got around about the hottest table in town, and the team are recording non-local Egyptian vultures and many other species coming to the feeding sites, including Griffon Vultures, Cinereous Vultures, Black Kites, Common Buzzards, Northern Goshawks and more.

At the moment one of the area’s local celebrities is also putting in an appearance every day.  A stunning adult Rüppell’s Vulture – supposed to be in sub-Saharan Africa but currently hanging out with our local Griffon Vulture colony and attempting to mate. Earlier in the Spring other vagrant individuals were recorded too, as this species gradually gains a foothold in Europe.

The project is supervised by the Andalucían Government and is coordinated with their vulture conservation team.  It is currently financed by the wind power companies.  In academic terms the project is still in early days, and nothing will be published until data has been collected for several years and the effectiveness of the measure can be properly evaluated.

In the meantime, it may not have a Michelin star or serve many vegetarian options, but Café Alimoche is definitely our new favourite eatery!

Thanks to our conservation partners and colleagues at Fundación Migres for the invite and our continued partnership.

If you love Vultures, you´ll love our Ronda & The Straits trip, timed to coincide with the virtually unknown spectacle of the Griffon Vulture migration across The Straits of Gibraltar.  Check it out here and get in touch to find out more – we´re currently taking no-obligation provisional bookings for 2020.

 

Make Birding Your New Normal!

Birding is good for you – it’s a scientific fact! The happy buzz that many of us know – and need – from spending time in Nature is gaining traction as a proven means of boosting mental health.

In England, for example, research revealed that access to urban green spaces reduced residents’ sense of isolation and loneliness. Living close to a park can offer an equivalent mental-health improvement as a two-point decrease in unemployment. And here in Spain, schoolchildren raised in greener neighbourhoods have more neural connections in brain regions tied to working memory and attention. It is also now becoming more commonplace for time in Nature to be prescribed as a treatment for depression.

Things have been tough for so many in these past weeks. Pain and worry over loved ones, employment and the future are of course very much still with us all, as society feels its way out of the international public health crisis caused by the coronavirus.

But as Spain transitions to a New Normal and we all step blinking into the late Spring light, we’re at last able to share the joy of experiencing the vast open spaces of Nature, and rediscovering its inhabitants, which lifts our spirits so much!

For our part, we’re thrilled to be able to start showing people birds again. As a small but environmentally- and socially-committed ecotourism company, we love running affordable day tours in our beautiful home of the Straits of Gibraltar. Since Cádiz province entered Phase 1 of lockdown de-escalation on 11 May, we have spent some fantastic days with our guests from the province, showing them the awe-inspiring Honey Buzzard migration, and all the other raptors that flow with it, as well as local specialities like White-rumped Swift and Northern Bald Ibis.

We have also teamed up with superb rural eco-lodge Huerta Grande to offer Spain-dwellers an affordable three-day Fly-away Birding Break in The Straits of Gibraltar. What better place to fly away for a short get-away, treat yourself to an escape from your lockdown residence and enjoy your new-found freedom in the wide-open spaces of the natural world?

Residents of Cádiz province can already join us on this trip. People from other Spanish provinces will be able to join us once Phase 3 of lockdown de-escalation is safely behind us all. This very special trip is available for a limited period, until the end of August.

The Straits is an ideal destination for this kind of summer birding, and not just for the cooling sea breezes and plentiful ice-cream! It is also home to interesting and unusual resident and breeding birds, some of which occur nowhere else in Spain. Rüppell’s Vulture, Spanish Imperial Eagle, Common Bulbul, Rufous-tailed Scrub-robin and White-rumped Swift are not only stunning to see but high on many birding wishlists.

Our Home – The Straits © Inglorious Bustards

A great variety of coastal, mountain and wetland areas put us in contact with some of the area’s most engaging species. Gorgeous Greater Flamingoes, characterful Northern Bald Ibis, awesome Griffon Vultures and rainbow-coloured European Bee-eaters make this an ideal place to kick-start your wildlife-watching habit and make birding your New Normal!

Over an introductory afternoon and two full days of birding, we’ll use our local knowledge of weather conditions, up-to-the-minute wildlife information – and of course your personal pace requirements and wishlist! – to bring you the very best of the area’s summer birding.

The itinerary will vary accordingly, but whatever your preferred birding level, with the Inglorious Bustards you can expect passion, knowledge, patience, laughs, complete commitment to sustainability and conservation, outstanding birding and wildlife spectacles, as well as our legendary picnics!

Of course, it should go without saying that the health and safety of our clients and avoiding the continued spread of this disease in wider society are still our top priorities. We have been working hard to keep abreast of all current rules and procedures for safe working and will continue to do so, for the good of everybody.

Though many of these common-sense procedures were already part of our trips, ensuring hygiene, safety and comfort for our guests, we want to reassure you that when you come birding with us, you can rely on the following:

– Our vehicle is thoroughly cleaned between every outing

– We ourselves are also thoroughly scrubbed between outings!

– Group size is limited. We are currently limiting group size to a maximum of four people (far smaller than the officially-allowed maximum of 10) to guarantee appropriate social distancing.

– Passenger numbers are limited to two per row of seats in our spacious, air-conditioned minibus.

– Any shared optical equipment such as telescopes or loaned binoculars will be sanitised at regular intervals throughout the trip and between trips.

– Your day will be spent outside and away from crowded places (that’s the joy of nature-watching!)

– A minimum distance of 2m between non-cohabiting participants will be maintained while in the field.

– Hand-sanitiser and disposable gloves are provided. We have sourced bio-compostable gloves as part of our continued resolve and commitment to eliminate non-biodegrable waste from our trips.

– Facemasks will be used throughout the day.  We ask our guests to bring their own reusable facemasks to avoid unnecessary disposable items.

– Any accommodation used or hostelry establishments visited are known and trusted, and verified to also be totally compliant with lockdown-easing procedures.

– Our legendary picnic lunch will be provided as usual – hygienically prepared, served on disinfected reusable crockery to avoid plastic waste and stuffed full of locally sourced, sustainably produced and delicious ingredients!

We are totally confident in our procedures and really looking forward to bringing you the natural high we all need right now – days out in Nature, not only good for health but good for the soul.

Return to Doñana

On a rainy afternoon we found ourselves reminiscing about our superb trip to beautiful Doñana earlier this year, in all its wintery wonder! It was perhaps the perfect antidote for our guests that week for their Northern European January.

Thousands of wintering waders, wildfowl and wetland birds filled the lagoons, ponds and saltpans, including Red-knobbed Coot, Marbled Duck, White-headed Duck, Black-winged Stilt, Little Stint, Caspian Terns, Slender-billed Gulls, Common Ringed, Little Ringed, Grey and Kentish Plover, Black-crowned Night Herons, White and Black Storks, Common Cranes, Glossy Ibis, Greater Flamingoes and Purple Swamphens.

As well as treats like showy Bluethroats, Little Swifts, Eurasian Hoopoes, Lesser Spotted Woodpeckers, Black-winged Kites, Booted Eagles, Iberian Grey Shrikes and a sneaky Lesser Flamingo, the group were lucky enough to encounter both of Doñana’s most famed Iberian endemics. In two wholly different experiences we shared the briefest of moments with an evaporating Iberian Lynx – soon followed by outstanding views of no less than SIX Spanish Imperial Eagles!

It is hard to know how we packed so much into just five days!

But we did, and we still had plenty of time to enjoy every species at a relaxed pace, sample sustainably-produced local food during picnics in the sun, and get to know the sandy streets and bar-side hitching posts of El Rocí­o.

You can read more on the tour page and in our trip report about the fantastic wildlife of Doñana.

As the world starts to think about arriving to a brave “new normal”, we all need something to look forward to.  As well as thinking back, we’re looking forward to seeing you in the future, and we’re currently taking no-obligation, flexible bookings on this and other trips for 2020 and 2021.

Loving the moths but missing the moth-ers!

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!

Moth-ing The Straits 2019 © David Grundy

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!

A tale of two Eagles

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…

Fourteen Kilometres of Joy and Sorrow

Travel Blogger of the Year

Read our award-winning blog about how a sudden drop in the wind on an autumn day in Andalucía inspires heart-stoppingly spectacular mass avian movement, but also provokes thought on travel, conservation and global change…

 

 

Fourteen kilometres of sea and sky are all that separate two continents. At 9am, the Mediterranean sun is already warming the air and sparkling on the calm waters. It’s early autumn, and this narrow – but potentially deadly – stretch of sea is all that stands between countless millions of birds and the next leg of their journey to African wintering grounds.

It’s been windy all week in The Strait of Gibraltar, making the crossing too dangerous for larger birds. Without the help of uplifting coastal air currents, they must power all the way, or face drowning. They’ve been stranded in the avian departure lounge for days and they’re hungry and desperate to continue their journey.

As mid-morning arrives, thermals form over the rocky coastline, and they’re finally cleared for take-off! In minutes, the sky fills with birds of prey. Eagles, Kites, Harriers and Honey Buzzards, swirl together in almost incomprehensible numbers and barge south along the suddenly congested flyway.

Chirpy European Bee-eaters pass over in vocal family groups, fifty at a time, quipping and chatting excitedly like they’re off on holiday. Clouds of thousands of White Storks form, sparkling black-and-white as the flock circles around on itself, turning the air currents to art.

The incredible spectacle continues all day, ending with streams of late arrivals racing over in their hundreds, seemingly experiencing `flyway rage´, desperate to reach Africa before sundown.

This breath-taking migratory marvel is beyond compare! During one rapturous, raptor-filled day at Spain’s most southerly point, I’ve counted over 20,000 soaring birds making the commute to the northern coast of Morocco – a mere fraction of the 450,000 that will pass through here in a season.

Imagine looking up from your tapas in Tarifa town and seeing layers upon layers of birds gliding overhead, stretching as far as the eyes can see in every direction, including ‘up’. It’s not surprising that this experience has the power to reduce many folk to tears! 

But it also has the power to provoke thought, about travel, conservation and global change.  With so much at stake, how do we help these feathered wanderers fulfil the yearly promise of return?  Must the joy of watching wildlife inevitably encourage consumption of the planet’s resources? How can our passion for travel and wildlife be channelled into a positive outcome for the environment?  How can we turn “eco-tourism” into a promise, rather than an oxymoron?

Even in the face of a global pandemic, we must not forget that climate change is still the biggest emergency facing our planet and the biggest threat to our survival, and that of so many other species. But it is easy to condemn travel, while conveniently ignoring agriculture and spiralling consumerism as major contributors to the emissions that cause global warming.

For many species, habitat loss, intensive agriculture and localised threats are the immediate emergency. Without travel, protected areas lose their economic value and habitats are forgotten. The voice to protect them inevitably becomes drowned out as they become meaningless to most, something you can only see on telly.

Without travel, we lose support for countless local conservation organisations, community businesses, and sustainable ecotourism endeavours, working hard to effect change at grassroots level. So too we lose understanding of our connection to the habitats, landscapes and cultures that Nature’s nomads pass through. 

From a conservation standpoint, the concept of saving species across flyways is an important one. After all, there’s no point fixing things for a wandering bird in its breeding grounds alone without giving it a helping hand across its entire migratory range. Places like The Strait of Gibraltar are rare, not just for their importance and natural beauty, but for their power to open people’s minds to migration and the interconnectedness of things.

By the end of November most of the birds of prey have passed through, and the skies of my home seem a little empty. But winter in The Strait brings its own visitors. Northerners seeking a bit of winter sun arrive in their thousands. Cranes fly in raggedly lines over the rice fields, bugling to one another. Tiny Chiff-chaffs and Blackcaps scuttle around the wild olive trees, waiting for the lengthening days to carry them back north.

Then one day in February conditions are suddenly right, and the first arrivals of spring are coming! Huge columns of Black Kites will be visible surging from the northern coast of Morocco, as if someone has popped open a bottle of champagne. Seemingly within minutes they’re arriving to the clifftops above Tarifa – my ringside seat for this migratory dance!

They have travelled from the moist forests of Africa, across the Sahelian scrublands and the Sahara, over temples, mosques and churches. They have overcome unstable and ever-widening deserts, persecution, pollution, habitat loss, and finally crossed this mere fourteen kilometres of sea and sky at the meeting of two continents. For me there is no bigger joy than a promise of return fulfilled.

Inspired by the brief to write about “My Favourite Place On Earth”, this blog first appeared under the title “Fourteen Kilometres Between Two Continents – 450,000 Soaring Birds Can’t Be Wrong!“, as part of Terra Incognita’s Travel Blogger of the Year 2020 competition.  It was placed in the Top 10 out of over 150 entries, by a panel of 20 judges including world-renowned travel bloggers, writers, conservationists and ethical organisations.

Maybe you´d like to experience the joy and sorrow for yourself?  Look no further than our migration tours and give yourself something to look forward to…

Mysterious migrations of the deep!

We often think of the Straits of Gibraltar as a barrier to be overcome, a great leap of faith for the hundreds of thousands of birds that must move between the land masses of Africa and Europe. But through the eons, other vast, invisible migrations have gone almost unseen in the dark depths beneath the sparkling surface.

Here we chat to our friend Aurelio Morales, owner of family-run cetacean-watching company Marina Blue, to find out why, for marine mammals, “The Strait of Gibraltar is a vast underwater canyon – a great corridor that links the Mediterranean and the Atlantic”

Aurelio has spent twenty-two years of his life around the marine fauna of the Strait of Gibraltar. “There is something special about this place that hooks me. Two seas, two tectonic plates, two continents, two prevailing winds… Each outing is completely different. There is no one equal to the other, since the weather and light changes, the behaviour of the species varies throughout the days”

His trips are full of encounters with our local resident delphids – Common, Striped and Bottlenose Dolphins, highly-sociable Long-finned Pilot Whales, and even Orcas in summer – but he is particularly fascinated by the mysterious movements and spectacular sudden appearances of the area’s two migrant species – Fin Whales and Sperm Whales.

“We have so many experiences with these two species that never cease to amaze me. We have seen on many occasions Sperm Whales jumping right out of the water, dragging a large body of water as if it were an explosion in the sea. We have witnessed fascinating interactions between Sperm Whales, Long-finned Pilot Whales and Bottlenose Dolphins. Yellow-legged Gulls will perch on top of a resting whale and clean its dead skin. We have seen Hammerhead Sharks circling them while they rest on the surface.”

But although they are seen regularly and often with great intimacy from Aurelio’s small yacht Miamita, much remains unknown about the movements of these two peaceful giants of the seas.

“We consider Sperm Whales to be semi-residents here. They spend long periods in the Strait feeding, mostly on deep sea squid.”

“In the Strait we almost invariably see adult males of up to 15m in length – and occasionally younger males of around 7-10m. They use this underwater corridor for their movements to and from feeding and mating areas.”

Male and female Sperm Whales generally don’t hang out. The males are loners, found in higher latitude cold waters, whilst the females, calves and young adults form gregarious and relatively sedentary groups in tropical and temperate seas. They meet up only to mate, with the males performing seasonal migrations. They find each other across vast distances – their huge jelly-filled heads directing and amplifying their song to volumes louder than a jet engine.

Research in 2011 used photo-cataloguing of tail flukes – from which individuals can reliably be identified – to compare Straits whales with records from across the Mediterranean and Atlantic. Of 47 Sperm Whales identified here, fifteen could be traced travelling throughout the western Mediterranean, a straight-line distance of up to a thousand miles.

The fact that none of “our” Sperm Whales from this study were recorded in the Atlantic supports existing genetic evidence of an isolated sub-population within the Mediterranean Sea. Believed to contain fewer than 2,500 mature individuals, the Mediterranean population is considered ‘endangered’, based on IUCN Red List criteria.

However, Sperm Whale social groups, with females and calves, do turn up in the Strait from time to time. We recall an incredible experience in September 2017, watching a group of ten females and young whales. They were grouped tightly together in a “marguerite formation”, where the group surrounds a weak or injured individual with their tails pointing outward, enabling them to protect it from attackers. The gathering seemed to emanate tension and anxiety, as the sea around them boiled with curious dolphins and seabirds eyed them suspiciously from above.

The happening was during a series of strong hurricanes over the Atlantic. Could this troubled group have been Atlantic in origin, having come into The Straits to shelter?

There is clearly more work to be done, says Aurelio. “Collaborative studies are currently being carried out between different companies, associations and scientists to verify that the same species seen in the Strait are being seen in other places such as the Canary Islands and Azores.”

Fin whales, the world´s second-largest living creatures, can reach lengths of up to 25m. They used to be abundant in the Strait of Gibraltar and nearby Atlantic areas until their rapid collapse due to intense whaling at the beginning of the 20th century. They are now considered endangered.

Evidence gathered from fifteen years’ worth of photo-identification suggest that some of the Fin Whales seen in the Mediterranean are actually of Atlantic stock.  A small community of them have been observed migrating through the Strait of Gibraltar, with remarkable seasonal directionality. They head to the Atlantic Ocean in May-October and the Mediterranean Sea in November-April. Observations of young whales exiting the Mediterranean Sea mainly in May-July suggest that at least part of this community is likely to calve in the basin, probably near the Balearic Islands.

“The Mediterranean is a semi-closed sea with warmer temperatures, so it would make sense that females raise their calves there until they gain enough weight to move to cooler feeding areas.” says Aurelio.

But, he says, there are many threats to these amazing creatures as they try to navigate the busiest shipping lane in the world.

“The greatest dangers for these large cetaceans are almost always related to human presence. The Strait is the only channel that connects the Atlantic with the Med and carries massive shipping traffic. Whales are injured colliding with large ships, and noise pollution interferes with echo-location, and therefore migration. Pollution from oil spills and plastic waste is another great problem that these animals face with this unbridled progress that prevails over the conservation of Nature.”

As a wildlife tour operator, and erstwhile skipper for the Ministry of the Environment, he feels a great sense of responsibility to make sure Marina Blue’s own effects on the environmental are only positive, in line with our own #FlywayPromise.

“There are thankfully many legal requirements to operate here, in terms of good practices regarding cetacean observation and compliance with EU emissions regulations and speed limits, which we naturally comply with. But we also have our own manual of good practices, guided by our own conscience and respect for Nature!”

“Marina Blue works in and for the Strait, with small groups of no more than ten people per trip to minimise our impact. We separate and reduce all our waste. We enjoy the animals with the utmost respect, quietly, allowing them to come to us if they wish. We must always bear in mind that we do not own this planet.”

We love heading out with Aurelio and his crew during selected trips, because of the intimacy of the encounters allowed by such a small vessel, but also because of his obvious deep connection and passion for the wildlife we are hoping to observe. With each spell-binding sighting of one of these incredible animals, we learn a little more about how to protect them.
