Inglorious Bustards sign up to Tourism Declares A Climate Emergency

tourism declares banner

Autumn migration is in full swing here in The Straits of Gibraltar.  As we watch raptors pour south across the narrow stretch of sea, witnessing part of their incredible journey is a complete joy.  But it also brings powerful mixed emotions – as we journey deeper into our man-mad climate emergency, these birds face a Sahara Desert that grows ever wider, erratic food availability, and habitat insecurity at both ends of their travels.

The Straits is one of the best places in the world to witness mass migration, an event which has the power to really open minds to the interconnected-ness of places, people and actions.  Inglorious Bustards believe passionately in that power as a force for positive change, but should we be encouraging people to travel to see it in these times of rocketing atmospheric CO2?

Globally, tourism is a 7 trillion-dollar industry and before the current pandemic it was continuing to out-grow the global economy.  Its carbon footprint accounts for around 8% of global emissions.  If its annual growth rate returns to pre-pandemic rates, tourism-related greenhouse gas (GHG) emissions will reach 6.5 gigatons per year by 2025.

But within tourism, eco-tourism is the fastest growing sector.  With it grows the potential to make travel truly sustainable and a force for good in the world.

Nature tourism – a significant “sub-species” of ecotourism – has recently been estimated to be worth nearly $350bn to the global economy each year, comprising around 4.4% of total global travel and tourism GDP.  It also employs over 20 million people.

The power of this could be immense.

When done right, sustainable tourism raises the profile of natural and cultural heritage, ensuring governments remain under pressure to protect it.  It gives economic and political value to important wildlife habitats.  It can offer an alternative income stream to local people.  It has been shown again and again to reduce damaging activities such as illegal logging, poaching and intensification of farming.  Not only does this have direct positive impacts for biodiversity, it also ensures important habitats such as tropical forests, mangrove swamps and peat marshes remain intact, their carbon locked away.

During the pandemic, we’ve seen global carbon emissions drop by about 8% compared to 2019.  Planes sat on tarmac all over the world and the tourism industry came to a complete halt.  But the effects of this grounding on emissions were tiny compared to those driven by reductions in global industry and ground transport.

Meanwhile the true toll in lost creatures and habitats due to the overnight collapse of the wildlife tourism industry may never be fully known.  Anecdotal evidence of the horrific side-effects for Nature are coming to light – poaching in Uganda for example has doubled during the pandemic, and in Kenya, desperate people who have seen their livelihoods wiped out are being forced to hunt endangered animals for food and income.

And here lies a huge problem for sustainable tourism. The negative impacts of travel and tourism, especially the GHGs for which we must all take responsibility, are well quantified on a global scale.  But it’s extremely hard to measure the positive impacts of the industry on habitat conservation.  By this I don’t just mean the local effects for people and key wildlife species, but for the planet as a whole, in terms of the carbon sequestered, water and air cleansed and all the other ecosystem services provided by habitat that wildlife tourism has directly or indirectly contributed to protecting.

I recently read a great article in which a nature guide in Guyana tried to quantify the immeasurable good in keeping habitats safe:

“If each visitor [from Europe] generates 2.8 tonnes of CO2 … and there are 200 of them, that makes 558 tonnes. … But look how much CO2 the Rewa community forests might be absorbing every year (350 sq km x 200): over 70,000 tonnes.”

It prompted me to try a similar quantification of good, taking our trips to The Gambia as an example:

When we take a birding and Nature-watching trip of eight people to The Gambia from Europe, the return flights generate 1.34 tonnes CO2 per person = 10.72 tonnes (carbon calculator, World Land Trust).

Once in-country, for a company that cares it’s relatively easy to have a low carbon impact here simply by adhering to good sustainable tourism practice and prioritising small, locally-owned businesses – which also give a more enriching travel experience and fantastic local food!

We also support an ongoing mangrove regeneration project, by our conservation partners The Gambia Birdwatchers´ Association, creating 2-3 hectares per year.  Mangroves sequester carbon up to five times faster than tropical rainforests, so we’re talking around 60 tonnes of CO2 per year just for the bit that´s already been planted!

A trip also:

  • directly employs 1 local guide and 1 driver for 11 days
  • enables 11 days training for an apprentice bird guide
  • pays entrance fee and local guide fee at 6 different community forest reserves, ensuring they are more valuable standing than logged
  • uses locally-owned accommodation and eateries at 3 different bases
  • employs local boat drivers during 3 river boat trips
  • puts on average €12,700 directly into the local economy

While recognising that offsetting alone is not a solution to our emissions, once we’ve eliminated all we can we then carbon-balance any remaining transport, food and accommodation emissions with the World Land Trust.  We also balance staff flights and encourage clients to balance their own.

But here’s the important bit: this income, multiplied up by all the wildlife tourists, ensures that areas like Bao Bolong National Park remain protected and valued by the area’s communities and the nation’s government.  This 220-sq km mangrove forest is capable of sequestering up to 220,000 tonnes of CO2 per year.  Not to mention the creation of diverse income sources for rural villagers so they are not forced to intensify farming and destroy native forests.

Of all global tourism, it is probably the wildlife tourism sector where eco-conscious potential travellers are most likely to make personal sacrifices to reduce their carbon footprint – including foregoing travel and avoiding flights.

So that is our challenge.  As conservationists, we believe passionately in the power of wildlife tourism to benefit Nature and people, in terms of socio-economic and cultural benefits, education and continued support for protected areas and wildlife habitat.

But we are of course only too aware of the environmental impact of the activities associated with our business.  Our challenge as a responsible ecotourism operator is to constantly seek practical solutions to minimise and eliminate negative impacts including our carbon footprint, so that when people travel with us, they’re benefitting, not exploiting the wildlife we see together.

There are many aspects to maximising our positive impacts and minimising the negative ones – such as eliminating plastic waste, avoiding wildlife disturbance and supporting local conservation projects – and we´re already working hard on this through our #FlywayPromise.

In relation to our carbon footprint:

  • We offer a high proportion of delicious vegetarian and vegan food on our trips, use only sustainably-produced extensively-grazed local dairy, and have one meat-free day per trip, used to highlight the fabulous veggie variety and provoke thought around food choice – keep an eye out for an upcoming blog on this…
  • During the booking process, we are on hand to advise our guests on the best overland ways to reach us, the most direct flights and the most carbon-conscious airlines.
  • We use modern, fuel-efficient vehicles during our trips and plan our routes carefully to avoid excessive mileage.
  • We use local guides, so for 90% of our tours, we don’t need to fly ourselves.
  • We strive to reduce all our emissions, and once we’ve eliminated everything we can we carbon-balance the remainder with the World Land Trust. We also balance any staff flights and encourage clients to balance their own.

But we feel the seriousness of the current situation requires us to go further.  As we emerge from the COVID-19 pandemic and people begin to travel once more, there is desperate need for carbon reform across the tourism industry.

That is why we are joining a growing movement to Declare A Climate Emergency.

We’ve signed up to Tourism Declares, an initiative that supports tourism businesses, organisations and individuals in declaring a climate emergency and taking purposeful action to reduce their carbon emissions as per the advice from The Intergovernmental Panel on Climate Change (IPCC) to cut global carbon emissions to 55% below 2017 levels by 2030.

Like all signatories, we have committed to the following five actions:

  1. Develop a ‘Climate Emergency Plan’ within the next 12 months, which sets out our intentions to reduce carbon emissions over the next decade.
  2. Share an initial public declaration of our ‘Climate Emergency Plan’, and update on progress each year.
  3. Accept current IPCC advice stating the need to cut global carbon emissions to 55% below 2017 levels by 2030 in order to keep the planet within 1.5 degrees of warming. We’ll ensure our ‘Climate Emergency Plan’ represents actions designed to achieve this as a minimum, through delivering transparent, measurable and increasing reductions in the total carbon emissions per customer arising from our operations and the travel services sold by us.
  4. Encourage our suppliers and partners to make the same declaration; sharing best practice amongst peers; and actively participate in the Tourism Declares community
  5. Advocate for change. We recognise the need for system change across the industry, and call for urgent regulatory action to accelerate the transition towards zero carbon air travel.

By nature, and as shown through our annual carbon footprint audit through the World Land Trust, our trips are relatively low carbon.  However, as a tour operator reliant on customers travelling, we recognise that just by publishing this declaration, we are opening ourselves up to accusations of greenwashing and – that new favourite word of the people who oppose progress – hypocrisy.

But it’s our responsibility to engage with the challenges we face head on.  Wildlife tourism is essential to conservation and must continue.  We’ll do everything we can to cut the carbon emissions we have any say over, encourage others to do likewise, and campaign for the wider system changes needed to move travel and aviation towards a low carbon future.

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?

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.

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!

Mangrove Magic!

Mangroves are truly magical.  They are capable of storing up to five times more carbon per hectare than tropical rainforests.  Their roots dissipate energy from storm surges, shielding local communities.  They cleanse waters of their sediments and pollutants before they enter the sea.  They are invaluable to local economies and support one of the world´s most biodiverse ecosystems.  All great reasons why we’re working with The Gambia Birdwatchers Association to conjure up a little more magic…

In difficult times like these, do you find happy memories shine even brighter?  It seems like an age ago, but way back in December 2019, we shared a magical moment with a Giant Kingfisher!

Having sat motionless for an eternity on the wires above our head, it finally decides it’s time to do some Giant Kingfishing!  It hits the waters of Kotu Creek like an avian breezeblock, emerging with a squirming silver fish that glitters in the Gambian sun.

That day of our trip to The Gambia was special in other ways too – it was our first opportunity to see the exciting mangrove restoration project being carried out by our conservation partners, The Gambia Birdwatchers Association. We are so proud to be involved in funding this work, and are equally thrilled to be fully funding the next phase of the project – restoration of a further two hectares, as part of our #FlywayPromise commitment to truly sustainable ecotourism.

Our friends Karanta, Tijan and the rest of the GBWA team proudly show us an area where a team of volunteers have painstakingly planted thousands of mangrove propagules on three hectares of mudflat, at the heart of Kotu creek.

It’s not fully understood what caused the dramatic dieback incident of this coastal mangrove some years ago. Some point to the dropping of raw sewage into the waterway by local sewage works, and the dumping of detritus and pollution from the tourist industry.

However, one of the major factors is believed to be land erosion. With offshore reefs degraded and many coastal mangroves gone, there’s nothing to protect this area from coastal erosion caused by rising sea levels. This has led to the gradual deposition of sand in the area, blocking the regular tidal flow, sometimes for weeks.

Upriver, mangroves are also under threat from unsustainable forestry.  Soil from deforested river banks washes downstream and clogs the River Gambia’s arteries.  They are also particularly vulnerable to climate change.  As temperatures and rain patterns change, larger tide volumes and higher soil salinity have deteriorated swamps across The Gambia and neighbouring countries.

Ironically, the fix for many of the main issues that face mangroves is – more mangroves.

As a carbon-sequestering ecosystem they are quite simply astounding – they are capable of storing up to five times more carbon per hectare than tropical rainforests. Most of it is stored in the soil around their roots.

Mangroves protect against weather shocks and other climate-related adversities. Their roots dissipate energy from storm surges, shielding local communities – and themselves – against floods. They contribute to cooling micro-climatic conditions in areas of often high temperatures. Their vegetation retains sediments and filters run-off water, preventing soil erosion and siltation, and removing pollutants before they enter the sea.

Economically, they provide spawning areas and habitat for some 33 species of fish and shellfish, oysters, mud crabs and clams, around 90% of The Gambia’s fishery resources.  They promote food sources, fishery income and biodiversity.  Managed sustainably, they also provide wood for homes and small community practices, such as fish curing.

The magic of the mangrove lies in its leaf litter. It produces large quantities, and as these leaves sink, taking their carbon with them to Davy Jones´ Locker, they begin a detritus food web, which forms the sludgy base for one of the world’s most biodiverse ecosystems. The invertebrates that inhabit the sludge feed West African Fiddler Crabs, Atlantic Mudskippers, and a myriad of fish, which in turn nourish West Africa Nile Monitor Lizards, Nile Crocodile, African Manatee, Gambian Mongoose and African Otters.

Some of our favourite birds seen on our Gambia trip are strongly associated with mangrove habitats in one way or another, including stompers like African Finfoot, Blue Paradise Flycatcher, White-backed Night Heron, Pel’s Fishing Owl, Greater Painted-snipe, African Fish Eagle, Goliath Heron, all the Bee-eaters and half-a-dozen kingfisher species ranging from the very common Pied to the Giant Kingfisher, which is now perched back above us at Kotu Creek.

Standing on the mud, Karanta explains some of the work that has already gone into our project. First of all, the team mapped degraded areas suitable for regeneration, and designed the planting areas so as to fit the natural shape of the creek and the remaining mangrove. Propagules were then reaped from different species within the local mangrove itself, ensuring local genetic diversity was continued.

An army of volunteers then completed the entire planting phase in a single day!  It was surely back-breaking work, slurping through the mud in wellies in the stifling 30º heat and humidity of the wet season, but we genuinely wish we had been there!

After planting it takes just 3-4 weeks to see positive results. A healthy 60% of the propagules survived, and by the time we visited in December the tiny mangroves-to-be were shrouded in a delightful green haze of fresh leaves. We can´t wait to see what they look like by this December, and also to see the next two hectares of the project coming to life!  As the mangrove returns, so will the invertebrates, molluscs, fish and the birds that rely on them. This and other projects like it will quietly stash away carbon and protect The Gambia’s fragile coasts.

But for the Kotu mangroves, arguably their most important role will be as a showcase for the nation’s biodiversity.  Tourism, including ecotourism, is hugely important to The Gambia, accounting for around 20% of GDP.  Its protected area network, as well as the country’s low intensity agriculture, forms a vital part of that income. But the tourist industry in this beleaguered nation is still trying hard to recover from a few bad years, as political unrest, Ebola and now travel restrictions due to COVID-19 have caused people to stay away in droves. If nobody is visiting, how long before natural habitats begin to come under pressure for short-term economic benefit in this, the 10th poorest country in the world?

Over 350 species of bird have been recorded in this busy tourist hub, many of them colourful and engaging. From this easily-accessible little gem of a nature reserve, the GBWA can reach out to the thousands of birding and non-birding tourists that make the nearby hotels their base.  A magical moment with a Giant Kingfisher reinforces the value of ecotourism, and adds a voice for the continued protection of The Gambia’s exceptional mangroves, forests and sahel.

Braving the Blades & the work of Fundación Migres

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.

37915581_486101738483981_8968695826415091712_n-1

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.

DSC06979

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.
