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.

Icons of Migration – How White Storks Have Inspired the Study of Migration for Centuries

Even in a place so packed full of natural migratory wonder as The Straits of Gibraltar, there are few sights as wow-inducing as a flock of hundreds – if not thousands – of migrating White Storks.  As they move along the coast in huge, glittering black and white columns, tracing the patterns of the thermals they ride, they really are the epitome of visible migration!

White Storks heading to Africa – July 2020 © Inglorious Bustards

These flamboyant voyagers capture the imagination and curiosity, and have been inspiring research into migration for hundreds of years.  Back in 1822, a White Stork turned up in the German village of Klütz with what was clearly an exotic spear lodged through its neck.  It turned out to be from central Africa.  At a time when it was still commonly believed that Barn Swallows spent the winter hibernating in the bottom of muddy ponds, this Pfeilstorch – ‘Arrow Stork’ – opened our eyes to the possibility of incredible avian journeys, and migration science was born!

Their great size, conspicuous presence and predictable return to nest sites makes White Storks fantastic candidates for study, and extensive ringing (banding) programmes were already underway as early as 1906.  From then until the onset of the Second World War, about 100,000 mainly juvenile birds were ringed, resulting in over 2,000 long-distance recoveries of birds reported between 1908 and 1954.  To this day, this wealth of information is arguably the foundation of what we know about where they travel and the routes they take.

White Storks breed extensively across Europe.  Almost like a watershed, there is a line that runs right through the middle of Germany, along which the westward-flyers separate from the eastward-flyers.  The eastern route leads over the Balkans, the Gulf of Iskenderun, the countries of the Middle East over to East, Central and South Africa.  The White Storks we see here, crossing over The Straits in such spectacular fashion have come from west of that line, their migration leading them down through France and the Iberian Peninsula to concentrate at this point.

For a bird with such a large wing span, flapping flight uses around 23 times more energy than gliding.  Since there are no thermals over the sea, they are driven to seek out the very shortest distance between land masses.  That means that, in an average autumn season, 150,000 White Storks of all ages – pretty much the entire western European population – are pushed towards this one point, looking for their moment to cross the 14 km (9 miles) of sea to Africa.  This gives rise to the spectacle of these huge gatherings, spiralling upwards on rising warm air until they emerge up to 1500 m above the ground and then gliding out into the blue.

From here they continue their journey south into Morocco, across the Sahara and down to their wintering grounds in central Africa.  In fact, having cheered them on in The Straits, we often get to see them again when we travel to The Gambia each December!

In the 90’s came satellite-tagging technology, a new way of gathering information about birds that was set to change the way we understand so many things.  Technology tends to be larger when new and unrefined – some of the earliest tags were the size of a brick!  Since a tag is required to be below 3% of a bird’s bodyweight to avoid hindering it, these gigantic nomads with their fascinating journeys presented the ideal species to take this new toy out for a spin!

This opened up the opportunity to study a whole new world of detail not just about migratory routes, but about migratory behaviour.  White Storks usually migrate in mixed groups of both adults and younger birds.  A number of studies have followed the fortunes of young Storks making their first migration without adults to follow, in order to look at the innate-ness – or not – of the journey plan.

Although their in-born sense of direction takes them vaguely in a south-westerly direction, if displaced by weather conditions they are unable to orientate themselves with any precision and many never fully migrate.  This is very different to small passerines, which migrate more-or-less alone, often by night, following an inherited map and with no guidance from adults.

The high importance of this social inheritance makes a great deal of sense.  As a day-flying, soaring bird, the efficiency of their route is heavily reliant on thermals generated by local topography.  They follow adults to learn an exact route – a kind of thermal highway – which on future travels they will be able to recognise visually and be sure of the optimum journey.

Tags also give us more information on the temporal nature of migration in these birds.  It turns out they treat it rather like a nine-to-five, flying for around 8-10 hours every day when the air is warmest, before resting until the following morning.  They barely take a day off, covering the 4,000 km (2,700 mile) journey from northern breeding grounds to sub-saharan Africa in two to three weeks.  Rather than feeding up before migration like some birds, Storks evidently snack en route only to meet their immediate needs, and lose weight on the journey.  Presumably when you’re reliant on literally being lighter than air, every invertebrate over-indulgence counts!

As satellite tags become lighter, cheaper and more precise, the insights they give us become ever-more fascinating.  In 2018 a project set out to explore how White Storks navigate thermals as a group by analysing individual high-resolution GPS trajectories of individual Storks during circling events.

A thermal is a complex, drifting, constantly changing column of air.  To thermal efficiently, birds need to adjust their flight speed and circling radius to find, and remain close to, the centre of the thermal where updraft is highest. Thanks to the precision of the data obtained from the tags, we are able to see that Storks navigate the thermal based not only on their own perception of the airflow in their immediate surroundings, but also on a complex series of social interactions, reacting to the movement changes of Storks within their nearby subgroup, as well as the leaders of the group at the highest vertical point in the thermal.

Arrows at the top depict time delays between switches relative to first individual. (d) Horizontal trajectories of birds that switched their circling direction.

How amazing to think that each Stork is effectively acting as an individual sensor, such that the whole flock becomes a distributed sensory array.  In this way, they explore and gather information on the thermal as a group, effectively mapping its structure and enabling them to use the optimal airflow within it.

From solving ancient mysteries to changing our perception of collective movement, to simply turning a good day into an amazing one, these really are inspirational birds.  And they are pouring over our heads at the moment here in The Straits!  We’re thrilled to be assisting as always our conservation partners, Fundación Migres, with the annual autumn migration count – to date over 38,000 of them have made the crossing, and we look forward to many more inspirational moments in coming weeks!

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.

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.

Crazy about Spring!

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!

Mothing at the gateway to Africa! A chat with moth-er extraordinaire @dgcountryside

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!
