The Worldā€™s Smallest Chameleon Now Discovered

Contributed by Megan Watson

A new species of chameleon, Brookesia nana, has recently been discovered in the mountainous forests of northern Madagascar. Measuring just less than 30 millimeters in length, it may be the smallest reptile ever identified, according to research published in Scientific Reports. Nicknamed B. nana for short,Ā this amazing species is a memberĀ of a genus comprising around 13 other tiny chameleons found throughout the region. Sadly, however, scientists expect the chameleon to soon be considered critically endangered.

The size of a sunflower seedĀ 

So far, only one adult male and one adult female specimen has been discovered. The male measures a mere 21.6 millimeters in length, while the female is significantly longer at 28.9 millimeters. Itā€™s thought this discrepancy in size (known as sexual dimorphism) may be the reason for the maleā€™s larger genitalia, which equals almost 20% of its body length, herpetologist Frank Glaw of the Bavarian State Collection of Zoology explains. However, at the moment, since only two individuals have been identified, itā€™s difficult to know whether these sizes are the norm for the species. Ultimately, itā€™s unknown why B. nana evolved to be so tiny, however it probably makes them more efficient at catching prey with their projectile tongues. Similar to other chameleons, B. nana uses its projectile tongue to catch tiny invertebrates like mites and springtails on the rainforest floor during the day.

The need for conservation

Unfortunately, habitat degradation and deforestation put a question mark over this tiny reptile’s future. The regionā€™s increasing population and poverty levels have forced inhabitants to clear rainforests for agriculture (94% of Madagascarā€™s previously forested landsĀ have now been deforested). As such, itā€™s likely B. nana will be officially considered critically endangered by the International Union for Conservation of Nature (IUCN). However, Sorata massif, the region where the B. nana was found, has at least recently been made a protected area by the Malagasy government.

Moreover, 36% of all chameleon species worldwide are actually facing extinction, the SSC Chameleon Specialist Group finds. Nine species are listed as critically endangered, 37 as endangered, and 20 as vulnerable ā€” resulting in 66 species of threatened chameleons in total. More than just chameleons, the whole reptile family is facing a bleak future with 19% currently threatened by extinction. In fact, an average of nearlyĀ one million endangered and threatened snakesĀ are legally sold every year on the international market, which puts snake species, human health, and entire ecosystems at risk. People looking to keep snakes as pets should at least choose species that arenā€™t endangered.Ā The Amazon Tree Boa The Amazon Tree Boa, for example, is currently classified as “least concern” by the IUCN.

How small is the smallest?

B. nanaā€™s minute size raises the question of just how small itā€™s possible for vertebrates to be. There are frogs, for example, that are still actually much smaller. However, surface area eventually becomes a problem for tiny creatures who, surprisingly, typically have larger surface area to volume ratios than big creatures. And, when these ratios are high, the more the animal becomes at risk of water loss. ā€œThere also seems to be a limit as to where you can put all the stuff you have,ā€ says researcher Tony Gamble. Many small creatures have reduced skull sizes or overlapping bones, and some lose entire structures through evolution.

Ultimately, this discovery serves as a reminder to everyone just how diverse the island of Madagascar is. ā€œI think what keeps stories like this front and center in our imagination is that every time something like this is discovered, itā€™s like, ā€˜Oh man, I guess [living creatures] can get a little smaller,ā€™ā€ says Gamble.

Chinese Paddlefish: Yangtze Giant Driven to Extinction

January 7, 2020

The world has officially lost another species to extinction after fisheries experts in China add the Chinese paddlefish to the list.Ā  One of the largest freshwater fish species, which had survived for millions of years, it hasn’t been seen since 2003.

Up to 23 feet long, the Chinese paddlefish was the giant of the Yangtze. And we killed it.

According to a report in CNN, the Yangtze River in China has lost one of its oldest inhabitants – the Chinese paddlefish, one of the largest freshwater fish species, has been wiped out by overfishing and habitat fragmentation.

The Chinese paddlefish, which is believed to Ā have lived since the Lower Jurassic period around 200 million years ago, hasn’t been seen for over a decade.Ā  Sadly, it is unlikely to be the last species lost the the planet forever.

As the world continues to lose species 1,000 time faster than normal, Saving Nature’s Stuart Pimm reflects on what we have learned about how many species weā€™re losing, where we are losing them, and how well weā€™re protecting them.

The species the world lost this decade

In this article for VOX.com. Brian Resnick makes the case that humans are killing earth’s biodiversity, now adding climate change to the list of causes.Ā Ā 

He collectively eulogizes the 467 species have been declared extinct and calls attention to others precariously teetering on the brink, and those experiencing serious declines in their population numbers.

The article highlights the casualties of the extinction crisis, the underlying causes for the loss of biodiversity, and the possibility of rescuing species from their current plight through thoughtful conservation interventions.Ā

In the face of climate change, species are fleeing to the poles and to higher elevations.Ā  Saving Nature is trying to help them get there.

HELPING SPECIES ADAPT TO CLIMATE CHANGE

Every year, the worldā€™s increasing population adds approximately 37 billion tons of carbon dioxide into the atmosphere from industry, agriculture, forestry, utilities, and transportation.Ā 

Deforestation ā€” of which the burning of tropical forests is the major component ā€” contributes about 10% of these emissions. It is also the principal driver of biodiversity loss.

Our unrelenting carbon dioxide emissions have surpassed the planetā€™s ability to absorb these greenhouse gases, leading to climate disruption and species extinctions.

Species Moving to Higher Elevations as the Climate Warms

While governments struggle with finding solutions for climate change, species must seek higher ground with habitable temperatures for their survival.

Even under the most optimistic scenarios, we arenā€™t going to reduce the high levels of carbon dioxide anytime soon. Species do not have the option of waiting. They are moving towards the poles and, in the tropics, to higher elevations. That is, when they can.

Some species may not reach the refuge of higher elevations and will go extinct. The cycle of deforestation and climate change blocks their passage through degraded wastelands. As a result, they become trapped them in an uninhabitable landscape, dooming them to extinction.

Evidence from a 40-year Study: 1978 vs. 2018

Ph.D. student, German Forero-Medina, under the direction of Dr. Pimm, examined the distribution of birds along an elevation gradient in the mountains of Peru. Forty years earlier, Dr. Pimmā€™s Duke colleague, John Terborgh, had surveyed this same mountain chain at various elevations.

Ā 

Returning to the original sites and using the same methods, the team compared where the birds are now versus in the past. Simply, they are at higher elevations ā€” though not as high as one expects.

Ā 

This suggests that the already threatened birds in the isolated patches of forest are in deep trouble. Isolation is bad enough, the inability to move to higher elevations is even worse news.

Saving Nature Builds Corridors to Safe Harbors

Our approach is a simple, effective, and scalable solution to reducing carbon dioxide and preventing extinctions. Restoring degraded land and reconnecting isolated forests achieves two objectives ā€“ it absorbs atmospheric carbon emissions and helps species adapt to climate change by finding safe harbor.

Ā 

Simply put, the corridors we create in biodiversity hotspots connect forest fragments and liberate species trapped and isolated in increasingly inhospitable habitats. By reconnecting isolated forests, we create vital migration routes for species seeking higher ground.

Ā 

In doing so, we get massive leverage by financing local partners to buy relatively small amounts of land to create significant protected refuges and strategic connections. Merging isolated forest fragments is critical to facilitating colonization of previously inaccessible areas. Doing so diversifies genetics and builds resiliency. In this era of climate change, the forest corridors also serve as the routes to survival as the climate warms.

How Can You help?

We will continue to use both science and savvy to connect, protect, and restore forest corridors. We invite you to join us in this ambitious effort!

Donating to Saving Nature puts trees in the ground for biodiversity, and sequesters carbon from the atmosphere. In short, supporting Saving Nature helps fight the two most pressing environmental problems the world facesā€”mass species extinction and global warmingā€”at the same time!

Horned Marsupial Frog Rediscovered in Ecuador

HORNED MARSUPIAL FROG REDISCOVERED IN ECUADOR

There is nothing more rewarding than learning that a species thought to be extinct has managed to somehow survive against formidable odds. The horned marsupial frog (Gastrotheca cornuta) is one such species.

Horned marsupial frogs are unique among amphibians. Named for the leaf-like horns on the top of their head and for the pouch on the femaleā€™s back to gestate tadpoles, they live in the rainforest canopy. The maleā€™s call, like the pop of a champagne cork, celebrates the mating season. Males fertilize eggs externally and place them in the femaleā€™s pouch. Here the developing tadpoles, with umbrella-like gills, eventually emerge as tiny frogs, without a having free-swimming phase.

Once having ranged from Costa Rica to Ecuador, their numbers have steadily dwindled as their habitat has been polluted and destroyed by commercial interests. Finally disappearing from sight in Ecuador in 2005, this reclusive amphibian was presumed to have succumbed to deforestation, the lethal chytrid fungus, agricultural pesticides, and crop fumigation.

It turns out that we havenā€™t lost them yet. A small population of horned marsupial frogs was able to survive in a remote area of the Choco rainforest. A team of scientists recently discovered six individuals and heard more vocalizing on a parcel of land our local partner acquire earlier this year. As the research continues, we hope to learn more about these survivors, as well as other isolated species taking refuge here.

The property is now protected as part of our broader vision to prevent large-scale commercial logging and oil palm plantations from intruding farther into what remains of this richly diverse tropical forest.

Western Ecuador ranks among the most threatened biodiversity hotspots in the world. The most threatened habitat is the lowland ChocĆ³ rainforest, which almost rivals the Amazon in terms of biodiversity but far surpasses it in terms of endemism and of course deforestation. The ChocĆ³ has more endemic birds than any other region in the world; it also harbors >2,250 endemic species of plants.

Having already lost nearly 98 percent of the original forest, the Ecuadorian Choco is facing the highest rate of deforestation in the country. We are currently developing an ambitious strategy to establish a mosaic of strictly protected reserves by building wildlife corridors that connect, protect, and restore disjointed forests.

Help us save the last 2% of the Ecuadorian Choco for the horned marsupial frog and thousands of other endemic species.

The Search for the Grey-winged cotinga

Clinton Jenkins produced this extraordinary map. It shows the State of Rio de Janeiro ā€” the city itself is to the left of the large bay at the western end of the image. Satellite images have been draped over a 3-D rendering of the mountains. Finally, Clinton colour-coded the areas with forest high enough to be possible habitat for the grey-winged cotinga. It was known from only two sites ā€” those labelled. Surely, we could find it in some of the other possibilities show in light blue!

Not all National Geographic expeditions go smoothly.

All adventures end at precisely the same point. Thirty seconds into the hot shower, a stream of dirty water runs down the drain. It takes with it the mud and dried blood, changing skin color from blotchy grey to pink, uncovers the until-now forgotten scrapes and cuts, and exterminates the thriving ecosystem of bacteria and fungi, each with its own distinct and pungent smell, to which my skin had been playing host.

This is exactly when one has the first dangerous notion that the last days or weeks might have been fun.

This expedition to remote and unexplored Brazilian mountaintops to lookfor one of the worldā€™s rarest birds was born in my comfortable, air-conditioned laboratory. Professor Maria Alice dos Santos Alves of the State University of Rio de Janeiro, Brazil, and I are sitting in front of a large computer monitor. On screen is a satellite image of the State of Rio de Janeiro. Overlaying other information, the computer tells us is that one of the biologically richest areas of the planet has been barely explored.

Someone has to go ā€” not ā€œbecause itā€™s thereā€ ā€” but precisely because in short order it may not be. This is one of the most damaged and threatened ecosystems on Earth. Within days, Maria Alice prepares her grant proposal to the National Geographic Societyā€™s Committee on Research and Exploration.

Within the year, she, her graduate student, Alline Storni, and I are stuck in remote cloud forest, abandoned by our helicopter pilot. We have noodles, tea, and trail bars for another two days and no idea what is the best path, if any, to take us out. Any path has to be one we cut ourselves.

The rainforests along the Atlantic coast of Brazil team with species found nowhere else on Earth. Some 8000 species of flowering plant, 200 species of birds and no one knows how many insects and fungi, are unique to these forests. Less than 6% of the forests remain.

TrĆŖs Picos is now a State Park and is a short drive from the city of Rio de Janeiro. It has spectacular scenery and contains very remote areas.

This is the front line of conservation.

Maria Alice and her colleagues must provide Brazilian State and Federal agencies with the best possible advice to prevent extinctions. She is spending a sabbatical at Duke University, working with Clinton Jenkins, one of my research group.

Using satellite images, data on elevation, and a broad knowledge of where bird species occur, theyā€™ll produce detailed predictions of where are the richest and most vulnerable parts of the Atlantic Forest.

The computer predictions find that generally different species of birds have been collected where the computer thinks they should be and not where they shouldnā€™t. Maria Alice and Clinton point to the glaring exception. The grey-winged cotinga, discovered in 1980 by Michael Brooke, has been found on only two mountaintops. Along a hundred mile ridge of mountains inland of Rio de Janeiro, others areas of high elevation forest should also be home to this species.

There are no records ā€” of this or any other species. Is the grey-winged cotinga more widespread ā€”Ā  and so perhaps less threatened ā€“ than we thought? What other species occur here? What is happening to these forests? This is biological terra incognito ā€” as exciting to us as those large blanks on the maps were to geographical explorers of the 19th century.

August 2003 and Iā€™m in Rio for a brief visit. Unexpectedly, the State government provides a helicopter for a day. Its two pilots quiz Maria Alice about her work, then become enthusiastic supporters. They give their day to fly us along the mountain chain from Serra do TinguĆ” in the west to Desengano in the east.

Itā€™s brilliantly sunny, with puffy white clouds for dramatic effect. We have a great day, with unrivalled views of the forests even if Alline does look a little green. Helicopter rides are particularly unnerving when the land falls away several thousand feet in a second as the helicopter crosses a ridgeline.

Three eastern mountaintops are visible from the city of Rio itself; TinguĆ” is the closest and so inaccessible that our pilots cannot find a place to land. They can at Araras, the next site, and east of TrĆŖs Picos ā€” three giant, sheer-sided pillars of granite rising several thousand feet from the forest below.

We work eastwards, preparing for the exploration that will begin in December ā€” mid-summer in the southern hemisphere. We land, check the safety of each landing place, and record it to the nearest yard on our GPS. Unbroken forest stretches for miles, but we also see the encroachment of farms that reduce the forest to tiny fragments, ones we know will be too small to support many of the original, unique and likely unknown species.

Into the mountains…

greywingcotinga2
The helicopter heads back to Rio de Janeiro. We never see it again.

Friday, December 5th, 2003. We lunch improbably in a luxurious home on the Fazenda Itatiba high in a valley a few miles from our intended camp. ā€œIt wonā€™t be like this when we get to camp!ā€ we joke with the fazendaā€™s administrator, ArgĆ©lio.

The helicopter cannot carry everything we need in one trip, but will ferry the team and equipment in short trips between the fazenda and the camp. Weā€™ve hired a private company this time. I just wish its pilot wasnā€™t wearing shiny black shoes, pressed black trousers and a white, starched shirt with epaulettes that vaguely suggest a naval uniform.

I fly on helicopter surveys across the world each year. Most pilots wear fatigues or tattered shorts, repudiate fashion, and have flight helmets that sport small insignia that hint of a previous life (ā€œDa Nangā€, for example) that one never brings up in conversation.

Thereā€™s a break in the clouds and Iā€™m off.Ā  Knowing the risks, I ensure that my tent, pack, water bottle, and the remains of last nightā€™s pizza are with me.Ā Ā 

As we cross into the next valley, the clouds break. Over the landing spot, itā€™s bright sunshine. The pilot doesnā€™t land and circles around. I jab my finger energetically at the flat area of grass and smooth rocks on which we had landed in August.

As we land, I know from experience that he should keep the engine running, holding the helicopter under power in case it slips. He reduces power and I prepare to get out. He signals me to stay inside it. OK, I understand that rule: he wants to shut down completely.

Hell no, he then gets out. If wind tips the helicopter, the still rotating blades will hit the ground and the resulting shrapnel will turn me into hamburger.Ā  I get out, grab my gear and move well away from the helicopter. I notice Iā€™ve a companion, a worker from the fazenda. In a minute, the pilot is off.

Fifteen minutes later, heā€™s back in our valley, but isnā€™t coming this way. He lands a mile or more below us in a depression. We wave. We strip off our shirts and wave them. Through the binoculars, I watch Alline and Maria Alice unload gear and the helicopter leaves. We will never see it again.

A silence descends. I slap on the sunscreen; I had the good sense to pack. My companion calls Maria Alice on our radio. ā€œI told at the pilot it wasnā€™t the right place, but he said your site was not safe,ā€ she tells me.ā€

So, why didnā€™t he then come to fetch us?ā€ I ask. ā€œI screamed at him that he had to. He ignored me and left.ā€

ā€œWell,ā€ I reply, ā€œyou have too much stuff to walk up to us, weā€™ll have to come to you.ā€

ā€œYour companion is called Gilmarā€ Maria Alice tells me. He wasnā€™t expecting to stay and has nothing but the clothes heā€™s wearing. And he didnā€™t bring any food.

Between us, we can just manage to pick everything up. It takes us three hours to reach Maria Alice and Alline. By that time, the sun has turned to rain and weā€™re sodden. The route is partly a bog filled with tussock grass six feet tall. A few yards takes us five minutes ā€” and another five to get our breath back. We head for a low forest, only to find itā€™s a tangled thicket of bushes and bamboo.

The only practical solution is to park the gear and cut a trail with the machete, then come back for the gear, and repeat the process. Weā€™ll have to make ā€œthe holeā€ our camp and explore from there. It would take three trips to get to our planned destination with all our gear ā€” at best, a long and exhausting day.

Alline (left) and Maria Alice band birds and record data ā€” all from the comfort of our tent. Our pjs were the only dry clothes we had.
Alline (left) and Maria Alice band birds and record data ā€” all from the comfort of our tent. Our pjs were the only dry clothes we had.

Maria Alice has already set up our mist nets. The nets catch small birds as they fly between the trees. My job is to listen for the grey-winged cotinga, to play a tape of its song to entice it to respond, and to record songs of birds we do not recognize.

We set up tents in the rain, glad we have a third for Gilmar. The final insult is the gas stove doesnā€™t work. As one attaches the burner, itā€™s supposed to puncture the canister through a rubber seal. It doesnā€™t. The prospect of cold food for two days sinks in. Out comes a pocketknife, we puncture the canister, and screw on the burner quickly before all the gas escapes.

Hot noodles taste so good in the field.

Saturday, December 6th starts cold and misty, then variously fogs, drizzles, sheets, spots, torrents, and all the other forms of rain for which we Britons have so many names. We band birds and listen for songs. Gilmar cuts a trail up the hillside to our north ā€” the direction of ā€œhome,ā€ the fazenda. ā€œJust in case something goes wrong,ā€ we tell ourselves.

What I hear on the trail is not encouraging. Scientists know almost nothing about the grey-winged cotinga. Itā€™s supposed to live just below the tree line ā€” just where we are. Itā€™s the other fact worries me.

The bird is supposed to occupy forest at a higher elevation than its closest relative, the black and gold cotinga. The latterā€™s song is one of the extraordinary sounds of the Brazilian mountains ā€” a pure whistle several seconds long, that rises midā€”point to half a note higher. The altimeter says we should be too high for it. Itā€™s so common here that the overlapping whistles create a continuous dissonance.

I return, soaked. As evening draws in, weā€™re all too cold to eat outside, so we eat inside my tent. Dinner is a protracted affair, hot noodles, soup, trail bars, nuts, chocolate, dry fruit, hot chocolate to drink. Weā€™re all in our sleeping bags to keep warm, our wet clothes piled up around us.

Tomorrow night weā€™ll be warm again, back at fazenda in the next valley, where the ownerā€™s generosity has extended to a night at his house.

Sunday, December 7th. I have never learned to love the sensation of getting out of a toasty, dry sleeping bag, and pulling on cold, damp rain gear, soaked socks and boots. Itā€™s raining; I will be wetter yet within minutes. Only hard work will generate the body heat to warm the cold clothes.

By 1pm, weā€™re hearing our helicopter every 15 minutes, or at least think we are. None appears.

We have no radio and cell phone connections in the ā€œholeā€. Gilmar takes a radio and cell phone and heads up his rough trail. After an hour, from his perch above the forest, he can reach us by radio and the outside world by cell phone.

The pilot is still at home.

That means at least an hour to get to the helicopter in the Rio de Janeiro traffic, longer still to reach us. ā€œI was expecting you to call me,ā€ he tells us.

A glorious place to get stuck!
A glorious place to get stuck!

Maria Alice is furious, for we all know how clear her instructions had been and the impossibility of us calling him from where he left us.Ā 

Ā 

Come in under the clouds and head up the valley from the southwest,ā€Ā  I ask Maria Alice to tell Gilmar to tell the pilot. The valley floor is still clear and the clouds above it are showing patches of blue sky. ā€œIf you canā€™t make it today, come first thing tomorrow.ā€

The pilot has abandoned us in a terrible place, one from which we cannot call the outside.

Thereā€™s no reason why he shouldnā€™t have been here. If he doesnā€™t arrive in the morning, it will be a disaster. Even if we can walk out, weā€™ll have to abandon all our gear and will be lucky to carry out our cameras and sound recording equipment. At some later date, weā€™ll need to come back by helicopter to recover it. This could delay the expedition for days, even weeks.

What do I tell National Geographic?

Maria Alice worries. It could be a lot worse: we have food.

Monday, December 8th morning. We pack for the hike out and by 9am are on our way. My tent is left up, with our gear packed as neatly as we can inside it. When we reclaim all that we must now leave, we want to be able to load it quickly. The rain has eased a bit.

The way out is simple and daunting. We know where we are and where we want to be ā€” to the nearest yard from our GPS. Itā€™s not far ā€” a few miles ā€” itā€™s just that there is a very large mountain in the way. We must go around it. Is to the left or the right better? Gilmar has told us the bad news: the forest has bamboo thickets, but above the tree line is worse. There are open areas, but they are bare granite on slopes too steep to climb.

We also know that the fazendaā€™s elevation is 1500 feet below our camp. Climbing up the mountain between us will be hard, but also mean that weā€™ll have to climb down those 1500 feet ā€” plus every extra foot we climb up along the way.

Stuat Pimm
Running out of tea would have been inexcusably inept. This is my last Fortnum and Mason tea bag.

Accidents are more likely going down than going up.

By lunchtime, weā€™re back in camp, wet, muddy from boots to hat, and smelling of rotten vegetation. After a thousand foot climb, we get radio and phone reception. We call the pilot, who incredibly thinks that we were going to call him to let him know when to come. He flew from Rio the previous afternoon, but gone to a town ten miles away and found it to be in the clouds.

That really angers us. Weā€™ll get a bill for a thousand dollars for a trip that didnā€™t come close to us at a time when the weather was good in our valley.

We also reach ArgĆ©lio at the fazenda by radio ā€” and thatā€™s the important news. Heā€™s coming to find us and heā€™s not coming the short way. Heā€™s coming up a different valley, though quite how and where is beyond me. Something about a tractor, Iā€™m told.

Afternoon. Gilmar and I head up the opposite side of the valley from our trail. On the steep, but just accessible, granite slopes, we see a small cleft. It opens into a spectacular valley running southwards, that joins another, even larger valley coming in from the west. At its far end is the massive granite pillar of one of the TrĆŖs Picos. Beyond this valley to the south, thick, white clouds cover the lowlands east of Rio de Janeiro.

Everything we can see is forest ā€” surely one of the largest tracts of forest left in these mountains. This is a glorious, wonderful place to be stuck!

At the valleyā€™s end ā€” it looks miles away and thousands of feet below us ā€” is a bright green spot. Itā€™s a pasture and we see three men, tiny specks even through binoculars. Gilmar is talking to them on the radio. He takes off his shirt, puts it on a stick and waves it. I take off my blue rain jacked and do likewise. How on Earth they are going see us in the middle of this mountain beats me.

We wave vigorously and, improbably, they wave back.

Perched on the granite bluff, I spend the afternoon looking across it, listening. Abundant black and golds call. Weā€™re above an exposed ridge, where the wind stunts the trees; this is supposed to be the grey-wingedā€™s prime habitat. If it were here, I would hear it. Clouds fall into the valley, then are swept up into the sky, and from time to time brilliant sunshine turns misty grey greens into bright patches of green, with yellow and purple flowering trees adding highlights. By 5pm, our rescuers are in shouting distance in the valley below. At 730pm, just as it gets dark, six of them enter out camp.

Tuesday, December 9th. It blew hard last night, but there was little chance I would lose my tent ā€” it had 7 men sleeping in it. Still, the wind snapped one of my tentā€™s poles and itā€™s oddly misshapen at first light.

Thereā€™s a trail bar and a cup of tea for everyone, one lump of sugar in each cup, except mine.

That exhausts all our food, but weā€™re happy. To run out of food before leaving, would have been inexcusably bad form. To leave our equipment behind would have been a disaster too: we just have enough helpers to carry it out.

Itā€™s downhill all the way, sometimes steep, sometimes through dense bamboo thickets, but mostly through forest with a closed canopy that shades the forest floor and keeps it free of undergrowth.

Every step, Iā€™m watch my feet, careful in where I place them, and use every handhold the trees and lianas afford. This is not the place to sprain an ankle.

An hour down, I see a bright orange frog on the ground.

Ā Itā€™s about the size of a dime and, as I admire it, others see another, then more. Thereā€™s a colony of about a dozen of them within a few yards. Bright and conspicuous, they are advertising that itā€™s not a good idea to touch them. When our companions do, we warn them not to touch their eyes or lips with their fingers.

ā€œWhat are they?ā€ we ask. ā€œDoes anyone know?ā€ While we donā€™t, Maria Aliceā€™s colleague at the university is a frog specialist, and weā€™ll ask him. Weā€™ve done this before elsewhere and the answer has sometimes been that no one has seen the species before.

We descend past other frog colonies, down into the valley, below where we black and gold cotingas whistle. Soon, weā€™re hearing bellbirds ā€” crowā€”sized, white cotingas that sound like cracked bells. There are more of them than any place Iā€™ve ever been. Their hearing so many rivals works them up into a calling frenzy.

The canopy is now far above our heads, the going more open, flatter. We come to a real trail. For the first time in days, we can stride along, rather than tentatively place each foot down. I feel warm. My clothes are drying. Three hours after we started, weā€™re in the open pasture we saw yesterday, looking back to where weā€™ve come, marveling that anyone could see us from this distance.

We hike along another trail, find another clearing, hike more, and then in the next clearing thereā€™s a tractor. How many people can you fit on a tractor? Ten ā€” and their equipment ā€” is the impossible answer.

On the back of a tractor, down a narrow trail a 4Ɨ4 would not navigate, past, then around the granite domes of TrĆŖs Picos, not fast, not elegant, but down and down, warmer and drier with each slow, bumpy mile until we make it out. We walk stiffly the last few yards to the hot showers.

On the beach at Ipanema.

By 7pm, weā€™re on the beach at Ipanema, having a beer with Michael Brooke and discussing our plans. We should be in Arraras by now, but Maria Alice will need a day to regroup, check the equipment, buy food, and most important of all, find another helicopter pilot.

I will now miss Araras, for I must leave on Friday night. My body demands I spend tomorrow soaking in a hot bath and drying my gear. Michael arrived two days ago and hasnā€™t come this far to watch the beach. We set our alarms for 5am.

Wednesday, December 10th. By 830am, Michael and I are slogging up a trail in Serra dos ƓrgĆ£os National Park heading for where he found the grey-winged cotinga 20 years ago. Itā€™s my only hope to see the bird now and, importantly, to see how the forest here differs from that near TrĆŖs Picos. Every muscle hurts as we climb hour after hour, stopping only for me to catch my breath.

We climb up through where the black and gold cotingas are whistling, then leave them below us. We listen, straining to hear the grey-wingedā€™s call. No such luck.

Thursday, December 11th. Thereā€™s so much excitement in Maria Aliceā€™s apartment as we pack the food, organize and check the equipment. In an instant, theyā€™re off, and Iā€™m alone. I wash my gear, write my notes, check my e-mail, enjoy a beer on the beach, listen to the BBC World Service after dinner.

I wasnā€™t expecting a phone call. From high on the ridge at Araras, exactly where they should be, exactly where I should be, Maria Alice has excellent reception. ā€œWish you were!ā€ Next morning, the phone rings again.

We have grey-winged cotingas calling all around usā€ she tells me. You really should be there!ā€

ā€œYes,ā€ I think, ā€œI really should be.ā€

Postscript

Maria Alice completed the work for her National Geographic Grant.Ā  It would have been impossible if she had lost all the equipment. In time, she published her work as two scientific papers:

Alves, M. A. S., S. L. Pimm, A. Storni, M. A. Raposo, M. de L. Brooke, G. Harris, A. Foster, and C. N. Jenkins. 2008. Mapping and exploring the distribution of a threatened bird, Grey-winged Cotinga. Oryx. 42, 562-566

Alves, M.A. S., C.N. Jenkins, S.L. Pimm, A. Storni, M.A. Raposo, M. de L. Brooke, G. Harris and A. Foster. 2009. Birds, Montane forest, State of Rio de Janeiro, Southeastern Brazil. Check List 5: 289-200.

On the flight in August, we had seen one possible site where we could drive up a road to see the bird.Ā  Andy Foster explored that area and found it there.

Two years after I wrote this story, I went to that site, found the bird and filmed and photographed it for the first time.
