Siamangs Play Nice With Baby Orangutan Aisha

Aisha learning the ropes

Aisha learning the ropes

All day long, Aisha can be seen on exhibit with the rest of the orangutans and now the siamangs, too. In December, after careful consideration, the introductions were made between Indah and Aisha and the siamangs. In the weeks prior, visual introductions were done inside where the siamangs could come near mom and baby but remain separate. We saw no negative interactions and even some interest from Aisha toward the siamangs. This lead us to believe that this time around should be different (ten years ago, the siamangs aggressively chased Indah and her baby, Cinta). And for sure, this time around was completely different.

Indah was in charge of the introduction from the beginning. Whenever she thought the siamangs were getting too close or too inquisitive, she chased them off and made them leave her. There wasn’t any aggression or fighting ever during the entire process. The siamangs were interested in Aisha and continue to be.

We see Unkie and Ellie play with Aisha (under Indah’s close supervision). They will grab her hair or arm or leg and Aisha will work at getting away and then as soon as she is ‘free,’ she goes right back to them. We also see them swing their foot near her trying to get her to grab it.

Karen has been interacting with Aisha more, hanging near her on the climbing structures. Aisha is spending more time away from Indah and Karen will go up into the tree to be near her. Janey hasn’t had much interaction with her but I figure once Aisha is on the ground more Janey will be playing with her and checking her out.

At 15 months, Aisha is near 15 lbs and has 2 canines coming in-16 teeth in total.

The orangutans can be seen in the exhibit from 9am to 4:30pm.

BONUS: Watch the video of Aisha’s first birthday

Mitigation-driven Animal Translocations Are Problematic – Study Indicates Importance of Science-based Animal Moves to Conservation

Turtles Fitted with Transmitters Released into WildThe use of animal translocations as a means to mitigate construction projects and other human developments is a widespread animal-management tool. A paper published today, produced through collaboration of conservationists from San Diego Zoo Global, the U.S. Fish and Wildlife Service, University of Kent UK, University of Newcastle and Amphibian and Reptile Conservation, reviews the success rates associated with these moves from a species-conservation standpoint.

“Mitigation-driven translocations outnumber and receive more funding than science-based conservation translocations,” said Ron Swaisgood Ph.D., conservation biologist for San Diego Zoo Global. “Yet the conservation benefit of the former is often unclear, since outcomes are often poor and rarely monitored. There are other, more strategic, priorities where our limited conservation resources should be allocated.”

The study, available online ahead of print and scheduled for the March issue of Frontiers in Ecology and the Environment the study estimates that millions of dollars are spent annually on moving animals out of the way of human interference, and may not be meeting the goal of preserving the populations as intended by legislation.

“Because mitigation releases are economically motivated, outcomes may be less successful than those of releases designed to serve the biological needs of species,” said Jen Germano, lead author of the paper. “Evidence suggests that many mitigation-driven translocations fail, although the application of scientific principles and best practices would probably improve the success rate.”

An additional challenge, pointed out by the paper, is the lack of information accompanying many of these translocations.

“Just determining how many animals have been moved and to what effect is challenging, since records are not kept or are difficult to obtain,” said Simon Clulow of the University of Newcastle, Australia. “This documentation is essential if we are to learn lessons and improve our methods.”

Researchers point to successful science-based animal relocations and releases as forming good models for the future.

“We’ve learned a great deal from carefully designed, conservation-driven translocation research over recent years, and this needs to be better applied to mitigation translocations,” said Richard Griffiths of the University of Kent, UK. “Unfortunately, mitigation translocations often do not meet the legislative intent of preventing the decline of protected species. This can be changed in the future to give these species a better chance at long-term survival.”

Animals Who Totally Own Winter

With a lot of the US experiencing record cold, and all this talk of another “Polar Vortex,” I thought it would be fun to explore how certain animals deal with extreme cold. Nature has concocted some pretty awesome ways to thrive in cold weather, often involving stylish winter coats, cozy fat insulation, and other clever mechanisms to overcome extreme cold. Check out these animals who absolutely own winter.

Takins have some pretty cool adaptations that help them stay warm and dry during the bitter cold of winter in the rugged Himalayan Mountains. A thick, secondary coat is grown to keep out the chill, which they shed for the summer. Their nose also plays a role in keeping them warm. A takin’s large, moose-like snout has big sinus cavities to warm up the air inhaled before it gets to the lungs. Without this adaptation, takins would lose a large amount of body heat just by breathing.

Polar bears have an outer coat of long guard hairs that stick together when wet and protect a dense, thick undercoat of fur. On land, water rolls right off of the guard hairs. Even though polar bears look white, their hair is really made of clear, hollow tubes filled with air. Scarring or residue on the fur can cause the “white” fur to appear to human eyes as cream colored, yellow, or even pink in the Arctic light. Fat also plays a major role in a polar bear’s ability to survive cold. Fat acts as energy storage when food can’t be found and may provide the ability to generate heat to help insulate polar bears from the freezing air and cold water. This 2-4 inch think layer of fat may also help the bears float in water. Big is beautiful!

Native to the Arctic region of the Northern Hemisphere, the Arctic Fox has a dense, multi-layered coat that provides excellent insulation against the cold. It also has an impressive layer of fat that provides extra insulation, as well as a a specialized body shape that minimizes exposure to cold. This cleverly adapted canine also has fur on its feet to help it walk on snow and ice without issue.

 

Snow leopards move to different altitudes along with the summer and winter migrations of their prey animals, so their coats vary from fine in the summer to thick in the winter. Snow leopards have a relatively small head with a short, broad nose that has a large nasal cavity that passes cold air through and warms it. Their huge paws have fur on the bottom that protects and cushions their feet for walking, climbing, and jumping. The wide, furry paws also give the cat great traction on snow.

 

Reindeer originally inhabited the tundra and forests of Scandinavia and northern Russia and were then introduced into Iceland, Greenland, Alaska, and Canada. They are covered in hair from their nose to the bottom of their feet, and have two coat layers: an undercoat of fine, soft wool that stays right next to their skin, and a top layer of long, hollow guard hairs. The air trapped inside the guard hairs holds in body heat to keep the animal warm against wind and cold. The hollow hairs also help the reindeer float, allowing it to swim across a river, if needed.

 

Sea lions have a thick, slick, waterproof coat that allows them to glide through cold water with ease and comfort. Their flippers also serve to regulate the sea lion’s body temperature. When it’s cold, specially designed blood vessel in the thin-skinned flippers constrict to prevent heat loss, but when it’s hot, blood flow is increased to these surface areas to be cooled more quickly.

Sea Lion

Incredibly adaptable, wolves have inhabited, at one point, virtually all of North America, northern Europe, eastern Africa, and Asia. Employing a wide range of adaptations, wolves tolerate a massive range of temperatures, from -70 to 120 degrees Fahrenheit (-50 to 48.8 degrees Celsius). All of their senses are keen, and they can run, climb, lope, and swim incredibly well.

 

Lastly, here’s an animal that not only doesn’t wear a winter coat, but is a natural nudist. Yeah, naked mole-rats wouldn’t do so well in extreme cold. Be glad you’re not one of these guys this season. Happy winter everyone!

10 Festive Reindeer Facts

‘Tis the season to be jolly! What could be more merry than Santa’s sleigh? Well, without his dexterous reindeer, Old Saint Nick’s mode of transportation would not get very far. So today, we would like to share a few fun facts about this festive species.

Wild & Fun: 10 Festive Facts About Reindeer

1. Reindeer or caribou?
In Europe, they’re known as reindeer. In North America, the term reindeer is used for Eurasian populations, while the name caribou refers to wild populations found in the country. However, both reindeer and caribou are classified as the same genus and species, rangifer tarandus. So for the purpose of simplicity and sticking with the holiday theme, we’ll call them reindeer for the rest of this blog.

Wild & Fun: 10 Festive Facts About Reindeer

2. Males AND females grow antlers.
Male antlers may grow twice as long as their female counterparts; still, reindeer are the only deer species to practice gender equality when it comes to their most memorable characteristic. Males begin to grow antlers in February and females start in May. Both stop growing around the same time, but a male’s antlers typically drop off in November, while a female’s remain through winter until their calves are born in spring. If you’re following this logic, our good pal Rudolph the red-nosed reindeer was most likely a female, because she was rocking her antlers on Christmas Eve.

Wild & Fun: 10 Festive Facts About Reindeer

3. Hard antlers start out soft and fuzzy.
Since antlers fall off and grow back every year, a reindeer is said to be in “velvet” while the new pair of antlers grow. After the velvet dries up, the reindeer unveils its hard antler cores by rubbing its deciduous horns against a rock or tree. Ta-da!

Wild & Fun: 10 Festive Facts About Reindeer

4. Reindeer calves are quick learners.
Newborns are able to stand one hour after birth, and they can outrun humans when they reach one day old. Calves are also weaned from their mothers as early as one to six months of age.

Wild & Fun: 10 Festive Facts About Reindeer

5. They have hairy feet.
Reindeer are built for subzero temps, so they’re covered in hair from their nose to the bottom of their feet. The hair on their hooves provides an excellent grip when trekking over frozen landscapes. Thus, the hairy hooves of reindeer have adapted into snowshoes for these Arctic animals.

Wild & Fun: 10 Festive Facts About Reindeer

6. Reindeer hooves are anatomically noisy.
“Up On The Housetop” and other holiday jingles often imply that the “click, click, click” we hear upon Santa’s arrival is the result of his herd’s stampeding feet. In fact, many hoofed animals make loud noises when their feet meet hard surfaces, but not reindeer. The metallic sound of reindeer hooves is actually due to tendons slipping over their foot bones as they walk.

Wild & Fun: 10 Festive Facts About Reindeer

7. They love crowds…
… of other reindeer, of course. Since they are social animals, reindeer live in herds of 10 to several hundred. So Santa was somewhat limiting his holiday herd by having only nine reindeer. Imagine the horsepower his sleigh would have if his herd included 100 fancifully named members!

Wild & Fun: 10 Festive Facts About Reindeer

8. Reindeer are good swimmers.
Santa’s exclusive herd might be capable of flying, but the rest of the species is not. However, since reindeer migrate to follow their food supply and avoid harsh conditions, chances are they come into contact with water. Luckily, reindeer use their wide, two-toed hooves like paddles that push water and allow these mammals to swim from four to six miles per hour.

Wild & Fun: 10 Festive Facts About Reindeer

9. Their eyes change color in winter.
To adapt to the varying levels of light in their northern habitat, part of a reindeer’s eye changes color and increases their vision sensitivity. The layer of tissue behind the retina that reflects light (tapetum lucidum) turns blue during winter and allows reindeer to see slightly more of their surroundings, even if what they can see is not that sharp or in focus. This seasonal trade-off has its advantages, especially if it improves a reindeer’s ability to spot predators.

Wild & Fun: 10 Festive Facts About Reindeer

10. Like humans, reindeer “wear” layers.
A reindeer has two coat layers: the undercoat is made of soft, fine wool that grows next to the skin, and the top layer consists of long, hollow guard hairs. Similar to a hollow-fill winter jacket worn by humans, the stiff top layer insulates the animal and keeps it warm against the wind and cold. These hollow hairs also help reindeer float. In other words, reindeer have incredible fashion sense.

5 Turkey Myths Busted

There are a lot of myths floating around out there about the bird that defines the holiday season, the iconic North American turkey. It’s time to bust some of those myths once and for all and hook you up with some trivia to share at the dinner table to impress your cohorts.

By jimbobphoto on Flickr

By jimbobphoto on Flickr

Myth 1 – Turkey was served at the first Thanksgiving
Common folklore holds that the turkey was an important food at the first Thanksgiving, but it’s doubtful the turkey was part of the holiday tradition until the 1800s. It’s more likely that other game birds were served, such as the now-extinct passenger pigeon.

Myth 2 – Turkeys are just big chickens
Turkeys are NOT chickens. The two birds are entirely different species separated by tens of millions of years of evolution.

Myth 3 – Benjamin Franklin wanted the turkey to be our national symbol
Benjamin Franklin never explicitly suggested that the US adopt the turkey as its national symbol, but he did once praise the turkey in writing as a more “respectable” bird than the bald eagle.

The ocellated turkey is native to Yucutan Peninsula, Mexico.

Myth 4 – Turkeys can’t fly
Wrong. Despite having one of the highest body-weight-to-wing-area ratios, turkeys can fly up to 55 m.p.h. and have been observed nesting in trees.

Myth 5 – Turkey makes you sleepy
It’s true that turkey contains tryptophan (an amino acid that produces serotonin, which helps regulate sleep), but most other meat has similar amounts of tryptophan. The sleepiness you’re feeling after that Thanksgiving feast is your body’s exhaustion from consuming an insane amount of calories.

9 Animals You Never Knew Existed

The precise number of animal species that exists on Earth, both past and present, is unknown. Following this logic, there’s a plethora of animals they didn’t teach you about in school. Sure, lions, tigers, and bears (oh my!) are cool, but if you’re looking to expand your knowledge of the Animal Kingdom or just want to stock up on fun #animalfacts, check out these nine exceptional creatures.

Bonobo

Before you mistakenly categorize this primate as a chimp, take a closer look. The bonobo is one of the most rare and intelligent primates in the world; they’re only found in a small part of the Democratic Republic of Congo and, among other things, their social structure is unique, complex, and largely peaceful.

Agouti

The agouti (ah GOO tee) is a rain forest-dwelling rodent from Central and South America. Given its diet of fallen fruit and nuts, it’s no secret that the agouti loves forest leftovers, but its sharp incisors also play a vital role in the survival of Brazil nut trees (one of the largest in the Amazon). This rodent species is the only mammal that can crack open the indestructible outer shell of a Brazil nut, which is extremely valuable for the country’s remote people.

Fossa

Madagascar is home to some incredible species, and the fossa is the “king” of them. Even though resembling a morphed cat-like dog, a fossa’s closest relative is the mongoose, but the misunderstandings don’t end there. Legends of fossas stealing babies from cribs, licking humans into a deep trance, and making their own pupils disappear are endless, but let’s be honest, we prefer facts over a lengthy list of myths.

Binturong

Imagine a buttery box of theater-style popcorn, and you can almost smell this next exceptional species. Yes, the smell that usually signifies box-office entertainment is the same smell you’ll find emanating from a binturong, aka bear cat. However, that moniker is a bit misleading since binturongs aren’t related to bears or cats but instead have closer ties to fossas mentioned above.

Echidna

There are only two types of egg-laying mammals in the world, and the echidna is one of them. If that’s not enough to spark your interest, this spiny anteater is also one of Earth’s oldest surviving species. While other animals have been busy evolving and adapting to fluctuating environments, the echidna has remained unchanged since prehistoric times.

Tamadua

Speaking of anteaters, the tamandua (aka lesser anteater) is another mammal you probably didn’t know existed. Its relative, the giant anteater, gets most of the attention, but the tamandua has its own way of making its presence known; it can spray a rotten-smelling secretion that’s said to be significantly more powerful than a skunk. Thus, its unforgettable nickname, “stinker of the forest,” is properly attributed.

Tree pangolin

The tree pangolin is a scaly anteater that looks like a pinecone with legs and a long tail. Its scales are made of keratin, like our hair and fingernails, which protect this “pinecone” from predators.

Tuatara

Sure, the tuatara appears to be an average lizard, but this reptile is truly unique. The tuatara is specific to New Zealand and its closest relatives are an extinct group of reptiles that lived during the time of the dinosaurs. It’s no wonder the tuatara is referred to as a “living fossil.”

Caecilian

Caecilians (pronounced seh-SILL-yens) live a mysterious life in a network of underground tunnels. There are over 120 species of caecilians on at least 4 continents, but almost nothing is known of this amphibian’s habits or lifestyle.

7 Animal Life-Hacks That Will Make You Jealous

Sure, our species has achieved some pretty amazing things, but some animals can do things that we could never dream of doing. Behold 7 animal life-hacks that will make you extremely jealous.

Seeing in the dark

Many animals can see way better in the dark than we can, but owls take the cake. Owls have the best night vision of any animal and can see up to 100 times better at night than we can. Talk about a sweet life-hack.

Built-in snorkel

Yep, you guessed it, elephants have us beat in the snorkeling department. They don’t need fancy, modern contraptions to breath underwater; all they need is their specially adapted nose. Fun fact: An elephant’s trunk has over 40,000 muscles in it and is nimble enough to pick up a leaf and strong enough to knock down a tree.

Freakish super-strength

Watch out Superman, the rhinoceros beetle might have you beat. Rhinoceros beetles can lift over 800 times their body weight. That’s equivalent to a human lifting a 65-ton M1 Abrams tank. Whoa.

Running as fast as a car

It’s well-known that cheetahs can run up to 70 miles per hour, but did you know that they can go from 0 to 60 MPH in just 3 seconds? That would leave most cars in the dust. I want that.

Living forever

Okay, well, not “forever,” but Galápagos tortoises live a loooooong time. It’s estimated by some scientists that Galápagos tortoises can live over 200 years. More than double our average lifespan? Yes, please.

Changing color

While most people think chameleons change color for camouflage, they actually do so based on mood, health, temperature, and light conditions–but that would still be a pretty sweet life-hack. Imagine everyone knowing not to talk to you because you’re that one color you turn when you’re just not in the mood. Awesome.

Flying

This is one thing we’ll never forgive nature for not giving us the ability to do. Humans have looked to birds with envy since the dawn of time for their ability to leap into the sky and soar, and we probably always will. Sure, we have airplanes, but it’s just not the same. :/

Can you think of any other awesome animal life-hacks? Let us know in the comments.

 

Matt Steele is the social media planner for San Diego Zoo Global. Read his previous post 7 Animal Myths You Probably Believed.

Animals that are active at night usually have large eyes that let them make use of any available light. With owls, the eyes are so big in comparison to the head that there is little room for eye muscles, meaning owls can’t move their eyes. Instead, owls must move their entire head to follow the movement of prey. However, having fixed eyes gives owls better focus, with both eyes looking in the same direction. And even though it seems that owls can twist their head completely around, most owls turn their head no more than 270 degrees in either direction. – See more at: http://animals.sandiegozoo.org/animals/owl#sthash.yTtEd37V.dpuf

7 Animal Myths You Probably Believed

When it comes to the Animal Kingdom, there’s a lot of misinformation out there, and some of it’s downright ridiculous. It’s difficult to know who to trust and where to go for reliable info. That’s where we come in. Even we have been known to make a mistake here and there (gasp!), but we’re here to set the record straight on a few animal myths that are widely believed–but definitely not true. Like really not true.

Koalas are bears

You’ve probably heard the term “koala bear” thrown around casually here and there, but contrary to popular belief, koalas have no relation to bears. While they have an uncanny likeness to teddy bears, they’re actually marsupials. Super cute, teddy bear-like marsupials.

Porcupines shoot their quills

A porcupine’s quills are made up of keratin, which is the same material our fingernails are made of. Can you shoot your fingernails? Didn’t think so. Just as we can’t shoot our fingernails (unfortunately), neither can porcupines shoot their precious defense mechanisms.

Ostriches bury their heads in sand

It’s hard to say where this ridiculous myth came from, but it could have derived from a behavior that ostriches exhibit when they sense danger. To avoid detection by predators, ostriches have been known to lay flat on the ground, placing their heads on the sand. Wherever it came from, let this myth officially be busted.

Mother birds reject babies if touched by humans

This myth probably comes from well-meaning people who fibbed to get other people to let nature take its course and avoid handling delicate baby birds. Actually, most birds have a very poor sense of smell and probably wouldn’t detect human scent. Regardless, handling baby birds isn’t a great idea.

Touching a frog or toad will give you warts

Many species of frogs and toads have wart-like bumps on their skin, and at some point it became widely believed that those bumps are contagious to humans. Truth is, warts are caused by a human virus and have nothing to do with handling frogs or toads. Strike that one down for good!

Camels store water in their humps

It’s known that camels are incredibly well-adapted to survive the harsh desert climates they call home, but their ability to avoid dehydration stems in part from oval-shaped red blood cells, not by carrying giant organic water jugs on their backs. Their humps actually store fat to tide them over on long walks through the desert where there is little to eat.

Lemmings commit suicide

No, lemmings don’t mindlessly follow each other to an untimely demise. This wholly unfounded myth may derive from population fluctuation among lemmings, with frequent die-offs and population booms. The phenomenon is still not well understood, leading to the belief that the small rodents boldly die by mass suicide for the good of the group. This misconception was reinforced by a scene in a 1958 Disney movie, White Wilderness, in which lemmings follow each other off a cliff to their death.

Yi Lu Ping An (Have a Good Trip), Yun Zi

The time has come to say goodbye to our good-natured young panda, Yun Zi. Yesterday, January 9, 2014. He embarked on his most momentous adventure yet—a move to his homeland. After crating up easily, our boy was loaded into a vehicle for the trip to Los Angeles, where he caught his flight to China. Thanks to the diligence and careful planning of our staff, he is well prepared for his journey.

The keepers worked to ready Yun Zi for all of the transitions he is about to make. He began crate training some weeks ago, getting used to the transport crate he will live in for a few days as he hops across the pond and heads up to the mountains of his ancestral homeland. As anticipated for such a smart and easy-going boy, he adapted to his new crate easily, spending time feeding inside it and accepting treats from his keepers through the openings of the crate.

Yun Zi Throughout the Years

Yun Zi Throughout the Years

Keepers have also been preparing him for the dietary transition he will undergo. In China, the pandas are not fed the low-starch, high-fiber biscuits and kibble they are used to getting in San Diego but instead receive a specially made formulation of bread that is foreign to our bears. Our keepers have access to that bread recipe and for some time have been whipping it up in our on-site kitchen so that Yun Zi could adapt to this new culinary staple. Thankfully, he had taken to the new bread, perhaps better than any of our returnees ever had.  This means dietary changes in China won’t be a big deal for our boy.

Since he is traveling in winter, staff wanted to prepare Yun Zi for the big change in temperatures he will experience. Keepers had been fattening him up a bit, and he has little rolls of flesh that will serve as extra insulation against the cooler mountain air. He looked nice and robust.

Staff has also prepared videos to leave with Yun Zi’s new Chinese handlers that detail aspects of the training he has received. This will help his new keepers to better understand the commands he has been taught, and, hopefully, will enable them to continue to use his training to facilitate future husbandry and veterinary procedures. Our video contains shots of Yun Zi sitting quietly while having his blood drawn, for example; his training allows this procedure without the use of anesthetic. This is a highly desirable, low-stress way to get biomedical data from him, and we wanted to be sure his new handlers are aware of his capabilities.

Yun Zi isn’t traveling alone on this voyage. He is attended by his primary keeper, Jen, who has been with him from birth. She had been actively engaged in his training, both during and prior to his preparation for departure to China. Yun Zi knows and trusts her, and this will be a comfort to him on his journey. In addition, a veterinarian is accompanying our boy on his flight, should there be any medical concerns to address. We anticipate that will be unlikely.

On Wednesday, the keepers began preparing his food bundles for the trip, and I know they were selecting choice bamboo culm to keep him content on the flight. Jen will ensure he receives regular munchies throughout the trip and will regularly refresh his water and clean up his crate to keep him comfortable. All of the plans and preparations are in place.

All that’s left now is to wave goodbye. 

Farewell, Yun Zi. You were a fun and exciting part of our panda research program. Even from far away, you will always be a member of our San Diego Zoo giant panda family. Yi lu ping an.

For the Love of Lemurs and Monkeys

Black and white ruffed lemur

I recently returned to Madagascar after a five-year hiatus. Even though these days I am steeped in research and conservation work in Asia, I was thrilled when the opportunity arose for me to revisit the island. As a scientist, I am not embarrassed to profess my fondness for lemurs because there is nothing embarrassing about transforming one’s passion into action. And lemurs are the reason why I became a primatologist in the first place.

I still vividly remember my very first lemur encounter. It was with a group of sifakas. In the lush rain forest, enveloped in a shroud of mist and fog and breathless from hiking up what I thought was the steepest trail in the world, I was astounded by the sheer beauty of these animals. There I stood, quietly watching the sifakas move about from tree to tree, so elegant in their posture, like ballet dancers pirouetting across an emerald stage. By the end of my field season, despite all the rain and leeches, I was absolutely hooked on lemurs!

Fast-forward 20 some years: Madagascar still excites me in the same way and my fervor for lemurs has not waned. At Maromizaha, which I visited on this trip, I was enthralled by the myriad of creatures that call this forest home. On my first morning walk, 6 of the 13 species of lemurs greeted me. Maromizaha, like many rain forests along the island’s eastern strip, is a true naturalist’s paradise!

Brown lemurs

The most impressive lemur is the indri. Weighing about 17 pounds, it is the largest living lemur species in Madagascar. Indris are known for their operatic singing ability. Often in the morning, male and female indris can be heard singing duets to announce their presence in their territory. There is another lemur in the forest with a well-endowed voice, the black and white ruffed lemur, although its vocalization is more a cacophony than a melody! Lemurs are so interesting to me because of their biology, and through this exploratory trip I hope to learn more about the lemur community in Maromizaha.

North of Maromizaha is a famous national park called Mantadia. Just a little to the west is another well-known preserve called Andasibe (also known as Perinet). These three forest parcels at one time were connected and quite large—but today they appear as isolated specks on a map. Slash-and-burn agriculture, logging, and mining are the main contributing factors to these ever-shrinking forests. From one of the highest points in Maromizaha, I could see where this paradise ends. Beyond is a much different world—a barren landscape devoid of all vegetation and lemurs. How do we protect a paradise like Maromizaha?

The answer is conservation partnerships with a focus on scientific research, local capacity-building, rural development, and education. So when my colleague, Professor Cristina Giacoma from the University of Torino, Italy, learned about the successes of our camera trap research, in-country training, and education program for schoolchildren in Fanjingshan, China (see posts What Might Monkeys Be Up To?, Monkeys, Leopard Cats, and Bears, Oh My! and March of the Little Green Guards), she invited me and San Diego Zoo Global to partner with her Biodiversity Integration and Rural Development (BIRD) project in Maromizaha.

This approach to biodiversity conservation is not new but it has been proven effective. Our initial camera trap work in Maromizaha and a survey of Malagasy children’s preferences and knowledge of wildlife have produced very promising (not to mention some surprising!) results. Cristina and I will soon meet in China where our partnership continues, and she will witness firsthand the ongoing conservation and research projects we have with partners in Guizhou and Beijing. There, our labor of love will help conserve leaf-eating monkeys, such as the highly endangered Guizhou snub-nosed monkeys and François’ langurs.
