Twycross Zoo is pleased to announce the birth of an endangered Bornean orangutan. The baby ape, born on November 28, is happy, healthy and doing very well. The newborn is 36-year-old Kibriah’s fourth offspring.

Great Ape Team Leader, Simon Childs, said: “We’re all very proud. Kibriah is a very loving mum and she’s doing such a great job. She is holding the baby very close so we won’t know if it’s a boy or a girl just yet. When we find out the sex, we can then start to think of a name for him or her. At this stage we don’t mind what sex it is, we’re just happy to have another healthy infant.”
According to Dr. Charlotte Macdonald, Head of Life Sciences: “The Bornean orangutan is classified as endangered on the International Union for Conservation of Nature Redlist (IUCN), with fewer than 50,000 individuals remaining in the wild. As they only give birth on average once every eight years their numbers are dwindling fast as a result of the extreme rate at which forest habitat in Indonesia is being destroyed by deforestation. Experts now agree that orangutans are likely to be extinct in the wild within the next 20 years, so successful breeding is imperative if this ape is to continue to exist on this planet in the future.”
Are you as polite as this marmoset monkey? Photo credit: BirdPhotos.com.
Princeton University researchers discovered that marmosets (a kind of new world monkey) take turns speaking with one another, similar to people! During their vocal exchanges, which can last up to 30 minutes, the monkeys wait their turn to speak. They don’t interrupt each other.
According to one of the study’s authors, Asif Ghazanfar:
“We were surprised by how reliably the marmoset monkeys exchanged their vocalizations in a cooperative manner, particularly since in most cases they were doing so with individuals that they were not pair-bonded with.
“This makes what we found much more similar to human conversations and very different from the coordinated calling of animals such as birds, frogs, or crickets, which is linked to mating or territorial defense.”
This research on marmoset vocalizations could provide clues about the early development of conversation in humans.

The Woodland Park Zoo and the Washington Department of Fish and Wildlife released over a hundred endangered western pond turtles to their native habitat in an effort to restore the population.
Western pond turtles once commonly inhabited the western coast of the United States. But several threats, including predation by the non-native bullfrog, disease, and habitat loss, put them on the bring of extinction since the early 90s.
In 1991, the Western Pond Turtle Recovery Project was established. Each year, recovery workers monitor adult female western pond turtles during the nesting season. They protect nesting sites with wire cages to prevent predators from eating the eggs. Then in the fall, the eggs and hatchlings are transported to the Woodland Park and Oregon Zoos where they can grow in safety.
“We return the turtles to their homes every summer once they reach a suitable size of about 2 ounces, a safeguard against the large mouths of bullfrogs,” explained Dr. Jennifer Pramuk, Woodland Park Zoo’s reptile curator.

Bella and Darwin, two female Galapagos tortoises, will be making their public debut at the Nashville Zoo on July 27. The pair are both 20 years old, and Galapagos tortoises can live up to 150 years. Bella weighs 280 lbs and Darwin weighs 200, but they aren’t done growing yet! Fully grown, they will weigh 350 lbs.

Their most recent release was 18 ornate box turtle hatchlings in the Upper Mississippi River National Wildlife and Fish Refuge near Savanna, Illinois. The zoo is also recovering other prairie-dwelling wildlife including meadow jumping mice and smooth green snakes.
“Suitable habitat is being created, but many species have trouble accessing it due to fragmentation from roads and other physical barriers which makes re-colonization of restored sites improbable,” explained Allison Sacerdote-Velat, Ph.D. reintroduction biologist at Lincoln Park Zoo.
“These collaborative conservation partnerships are terrific because each agency brings a unique expertise. The zoo specializes in small population biology and animal care. We can successfully breed, hatch and care for these species until they are large and mature enough for release to the wild – a technique called ‘head-starting’ which gives them a greater chance of survival upon release.”
