Leaping Lemurs!

Ring-tailed lemurs at Oakland Zoo

Madagascar, an island off the east coast of Africa, is a beautiful hotspot for biodiversity.  It is estimated that 90% of the plants and animals living in Madagascar are endemic, meaning they occur nowhere else in the world!  Unfortunately, the island nation (about the size of the state of Texas) and its inhabitants are facing some extreme threats.

While it may be rich in biodiversity, the Malagasy people are among the poorest in the world.  It is estimated that over 92% of the population lives on less than $2 per day.  A military coup in 2009 caused further economic instability, and the subsequent anarchy increased the illegal logging of rosewood.  One of the few reliable sources of income, thousands of Malagasy people flocked to the rosewood forests to support their families.  In addition to the problem of rapid deforestation, many people turned to lemurs as a source of protein, illegally hunting them for bush meat.

Lemurs are the most endangered mammals in the world.  Of the 101 species of lemur in Madagascar, IUCN considers 60 of them endangered or critically endangered.  Another 20 species are considered vulnerable.  Lemurs are prosimians, meaning that they are primates, but still maintain many “primitive” characteristics of other mammals such as the bicornate uterus.  Like other primates, they do possess opposable thumbs and fingernails rather than claws.    Oakland Zoo houses two species of lemurs, Ring-tailed lemurs and Sclaters or Blue-Eyed lemurs.  Blue eyed lemurs have been listed as one of the 25 most endangered primates for over 6 years.

Conserving lemurs is critically important for the biodiversity of Madagascar.  While logging of Rosewood is illegal, the political unrest that has been extant in Madagascar for over 4 years has allowed it to not only continue, but to increase.  Rosewood is valued for its rich color and hard texture, making it good for furniture.  While the supply comes from Madagascar, the demand for this wood is right here in the US and throughout the western world.  Recently, the Malagasy people elected a president and hopes are high that a stable government system will rein in the illegal logging and poaching practices that have become commonplace.

However, the fact remains that rosewood is mainly sold to westerners.  If the demand were lower or nonexistent, the motivation for deforestation would be almost nonexistent.  So what can you do to protect lemurs in Madagascar?  Do not purchase furniture made from rosewood, and educate your friends and family about the plight of the lemurs.  Email or call Genny Greene (genny@oaklandzoo.org or call (510)632-9529 ext. 167) to learn how you can win a special Behind-the-Scenes visit with our very own lemurs here at Oakland Zoo. Your special visit will include an actual in-person live painting made by our lemurs made just for you. All proceeds will go to lemur conservation efforts in Madagascar (see below for more detailed information). And don’t forget to go see the new IMAX film – Island of the Lemurs which opens on April 4th.

**All proceeds from the raffle benefit lemur conservation through Centre Val Bio.  Centre Val Bio is a research station in Madagascar run by Dr. Patricia Wright who has been studying lemurs for more than two decades.  She is the founder of Centre Val Bio and the Institute for the Conservation of Tropical Environments which led to the establishment of Ranomafauna National Park in Madagascar.  Dr. Wright was the sole scientific advisor for the upcoming IMAX film “Island of the Lemurs” which will be released on April 4th.  For more information:   http://www.stonybrook.edu/commcms/centre-valbio/index.html

Internship Week 1: My first week at Oakland Zoo

by | July 12th, 2012

Intern Stephanie Lo

Throughout the next few months, I am an Oakland Zoo intern who is working on String 7. This particular string consists of a variety of domestic and exotic animals, all located in the Wayne and Gladys Valley Children’s Zoo section. I chose to participate in the Oakland Zoo’s intern program to explore my interest in veterinary medicine and to learn about animal care techniques of zoo animals. As an intern, I work three full days per week at the zoo for a total of 288 hours of service.

On my first day, I met the String 7 Zookeeper named Liz along with another intern who works on the same string as I do. We began the morning by striding up the stairs towards the cat room, where the three cats reside at night. Located adjacent to the goat and sheep barn, the cat room contains the litter boxes, cat furniture, and food and water bowls. During the day, the three cats named Billy, Cali and Scarlet are free to roam around the contact yard. The other intern and I swept out the cat room, scooped the litter boxes and replenished the food and water dishes before heading towards the pig barn.

The pig barn houses three domestic pigs and two domestic rabbits. In the mornings, I typically feed the pigs their breakfast, which consists of a measured amount of pellets. One of the pigs also receives a specific quantity of medicine mixed into her morning meal. While the pigs consume their breakfast, the other intern and I scoop up the manure around the exhibit and rinse out and refill their water bowls. To extend the animals’ feeding time, we may fill enrichment toys with produce so the pigs have to roll around the toy to make the food come out of the holes. The particular enrichment toys we used on Thursday were plastic Arrowhead water containers with circular holes cut in the sides, allowing the chopped produce to fall out in intervals. Liz showed us other forms of enrichment, which included scattering produce around the exhibit and brushing the pigs.

A hotspot of the Children’s Zoo is the Contact Yard of the goat and sheep barn.  As an intern, I may supervise the Contact Yard to ensure that all the visitors follow the rules posted. There are eleven goats and four sheep housed in the barn, and visitors oftentimes enjoy brushing them. The sheep can be a bit skittish, but the Pygmy goats are quite tolerant of brushing and petting. Although visitors may assume the Pygmy goats are overweight or pregnant, the goats are actually bred to be shorter but they still have the same sized digestive system, making their bellies appear proportionally wider.

Some of my favorite animals on String 7 are the five ring tailed lemurs and two blue-eyed lemurs. During my first day, the other intern and I got the opportunity to accompany Liz into the lemur exhibit and help her with the morning feeding. The male lemurs are subordinate to the females, so we scattered food throughout the exhibit to ensure they all had access to it. To improve the lemurs’ mental health, the zoo keepers provide specific types of enrichment every day and mark them on the calendar.

In addition to the hands-on experience under the string’s zoo keeper, interns also attend weekly classes and behind the scenes tours. This week’s class titled “Emergency Response in a Zoo Setting” focused on how the Oakland Zoo responds in emergency situations. The various situations included both natural disasters and animal escapes, which could result in calling a Code Yellow, Code Red or Code Pink. The other intern class highlighted public interaction strategies with the zoo guests.

Stepping through ZAM: Day 5, Children’s Zoo Module

All Zookeepers are comedians. Well, that might not be true, but the three we have met so far have been a lot of fun to listen to. I guess you have to have a sense of humor if you are going to follow goats or bats around all day at the Oakland Zoo.
Zoo Org Chart
Tonight we heard about how animal management at our Zoo is organized. The animals are divided into Strings and a primary zookeeper is responsible for each String. The Strings usually, but not always, correspond to where the animals live in the Zoo.
This can result in some strange collections for a zookeeper to care for. For example, tortoises are in the same String as zebras. Hornbills are cared for by the same keeper as the chimps. Lemurs go with the rabbits. Who knew?
Each String has, at the very least, a primary and a relief keeper plus a floating keeper who roams from one String to the next as needed. The elephants make up a string all by themselves and it takes four full-time keepers to manage their daily pedicures and all their other needs.
Margaret Rousser, who supervises the nine keepers related to the Children’s Zoo introduced us tonight to our River Otters and Bats.
Margaret Rousser, Zoological Manager
Our Zoo is part of the AZA Population Management Plan (PMP) for River Otters. The  two otter pups born here last spring, were the result of the AZA deciding that our otters had the right genetic strains to breed.
When Tallulah and Ahanu are at least a year old they likely will move to another AZA-accredited zoo to carry on the PMP program there. This is the way species are preserved in Zoos. There are dozens of these programs in operation throughout our Zoo.
Our River Otter pups
Did you know that animals raised by their own parents become better parents to their own offspring? Our otter pups were taken care of so well by their mom that our staff couldn’t even hold them at 12 weeks: they were just as wild as if they had been born on a riverbed somewhere. They are trainable, so that they can be cared for by our staff, but will never be tame and that’s what we all want. AZA zoos freely give each other animals so that species can be preserved.
Flying Foxes (AKA Fruit Bats)
Our Fruit Bats represent only two of over 1000 species of bats in the the world. The Malayan Flying Foxes,  our largest, have a wingspan of up to 6 feet. The Island Flying Foxes are smaller and sometimes visitors think they are babies. They aren’t, and we won’t be having any because all our bats are male.

Bats have fruit, heat and teddy bears to make them happy here. The toys were the creative idea of their keepers concerned that the  males were having trouble controlling themselves during mating season and this was causing injuries. When they were given stuffed toys, they all “bonded” with the bears instead of each other. We give our bats a temperature-controlled house for them to go in and out of, a huge aviary, and a balanced diet that they have to be tricked to eat. They love fruit, so we toss it in a sauce made of veggies and powdered vitamins. Fruit Bats are ideal for zoos because they are active in the daytime. Insect Bats would be pretty boring to watch because they go hunting at night and sleep all day.
Life in the Contact Yard
The animals in our contact yard (sometimes called the petting zoo) were introduced to us by Liz Abram, their keeper. It’s the only place in the Zoo where people can touch the animals, so we future docents needed some tips to pass along to the kids. It’s all about safety: don’t pet a goat’s head because he will butt you, wash your hands after petting the animals or being in the yard, don’t pick up stuff off the ground, wear shoes.
Here are just a few fun facts from Liz’s presentation:
Goats are social, Sheep are shy. Sheep can’t raise their tails, but goats can, and goats have beards which our sheep don’t. Sheep that shed are used for meat. Sheep that are used for wool don’t shed and have to be shorn. We have the shedding kind and brush them regularly. The wool that is brushed off gets used in other animal’s enclosures for sensory enrichment.
Our Pygmy Goats aren’t pregnant, they are just built that way. They have a two-chambered stomach like cows and they’re stocky because they were bred for meat.
Nubian Goats have long ears for the same reason rabbits do: to regulate their body temp. Elephant ears function the same way. So do horns on animals, surprisingly.
Long ears help keep the Nubian Goat cool.
The ears and horns are loaded with blood vessels that, being so close to the surface, allow the blood to be cooled as the ears are flapped or the horns run through a breeze.
Guinea Forest Hogs are a rare domestic breed and there are only about 200 left in the world. We have two of them.
Our puppy and kittens are new to the Zoo and in training to be Pet Ambassadors to kids who might be fearful of dogs or cats or might not have the chance to have their own pets. Our instructor, Sarah, predicts that Lily Rae, our Golden Retriever pup, will soon become kids’ most popular animal in the Zoo.

Saving the few Lemurs that are left
All Lemurs come from Madagascar and, because of habitat destruction and hunting, are highly endangered. They have already lost 90% of their home turf.
Our Ring-Tailed Lemurs are part of the AZA’s Species Survival Plan (SSP). SSPs actively keep endangered species going in captivity with as much genetic diversity as possible.
The little Blue-Eyed Black Lemurs are the only primates besides humans that have blue eyes.
Like Elephants and Meerkats, Lemurs live in matriarchal societies. The young males are kicked out of their family group when they are old enough to mate to prevent inbreeding.
This Ring-Tailed Lemur backs down a tree like it’s a fire pole.

To merge with another tribe, male Lemurs have to move in on another male’s turf and they do this by conducting Stink Wars—an amusing but peaceful way of establishing dominance. They have musty scent glands on their wrists that they rub against their tails and then they flash their tails at each other to see who has the strongest smell. The winner gets the females and a chance to breed. I’m guessing the loser is grossed out and takes a hike.

The island country of Madagascar has one of the most diverse animal populations on earth, yet species are disappearing every day. If you’d like to learn more about Lemurs and the other animals being pushed off the planet by population explosion and tree-cutting, start here.
You can help rainforest animals by using only paper and wood with the FSC (Forest Stewardship Council) certification which assures it came from a sustainable forest. The Oakland Zoo uses FSC wood or wood substitutes whenever possible.
Tonight’s homework is to explore what pets are and aren’t—300 words minimum. Better get started. While I’m doing that, you can be thinking: What is a pet?
Talk to you Saturday,
Franette
