Zookeepers have always assumed giraffes were fairly silent creatures, with the occasional snort thrown in. The assumption was that their long necks restricted their ability to make sounds, and also that being noisy would attract predators.
But researchers from the University of Vienna challenged this assumption. After recording and studying 938 hours of giraffe sounds over an eight year period, the scientists have discovered that in fact giraffes do make sounds. They make low-pitched humming sounds at night.

A rare pink bottlenose dolphin was recently captured on video by charter boat captain Erik Rue. Pinky was first spotted by Rue in 2007. To everyone’s delight, Pinky made another appearance eight years later, and she might be pregnant!
According to scientist Greg Barsh, Pinky is most likely an albino. The pink hue comes from the blood vessels showing through her pale skin, which has no color. Albinism happens when there is a genetic mutation. The cells that make melanin, which produces the color in hair and skin, fail to make enough pigment, if any at all. People who have albinism have very pale skin, eyes, and hair.
Albinos can suffer from skin and vision issues as a result of their lack of melanin. Animals with albinism may be easily spotted by predators because they lack the appropriate camouflage. Therefore, albino animals, such as Pinky, are very rare in the wild.

Visitors to the Taronga Western Plains Zoo in Dubbo, Australia delight in the new koala joey on view. Named Storm, the seven-month-old joey is the first koala joey of the season to emerge from his pouch.
This is the second joey for mother Wild Girl. Wild Girl came to the zoo’s wildlife hospital after she suffered a hip wound after being struck by a car and was unable to be returned to the wild.

“Thunder is approximately seven-months-old, born in January 2015. Wild Girl is quiet protective of Thunder. He can be seen on the front of her chest for now but in the coming months will start to move on to her back,” said keeper Karen James.

A juvenile great white shark beached itself in Chatham, Massachusetts yesterday. With the help of beach goers, the harbor master, and the Atlantic White Shark Conservancy, the shark was able to safely return to the water!
World conservation first: An orphaned tree kangaroo was cross-fostered by a rock wallaby and survived! Photo by Adelaide Zoo.
The keepers and veterinarians at Adelaide Zoo have saved the life of an orphaned Goodfellow’s tree kangaroo by using a surrogate wallaby mother! This exciting achievement is a world first for conservation.
One morning in November of last year, zoo keepers discovered that a tree branch had fallen and killed the zoo’s three-year-old tree kangaroo overnight. She was carrying a five week old joey. Since the joey was so young, hand-rearing was not an option. They decided to use a technique called “cross-fostering”, which involves transferring the joey to the pouch of another animal.

In the 1990s, Adelaide Zoo pioneered this cross-fostering technique on endangered wallabies. In this situation, zoo keepers would transfer the endangered wallaby joey to the pouch of a surrogate wallaby of another, non-endangered species. The original endangered wallaby female would then be able to restart her breeding cycle, increasing her reproduction rate up to six or eight times. This allowed the zoo to build up the endangered population much more quickly.
According to Adelaide Zoo veterinarian Dr David McLelland, “We’ve had great success over the years’ cross-fostering between wallaby species, but the specialized breeding technique has never been used on a tree kangaroo. Not only are tree kangaroos distant relatives of wallabies, they also have many behavioral and physical differences. We had no idea if the yellow-foot rock wallaby would accept the tree kangaroo joey, but if we wanted to save the joey we had to try our luck.”
The gamble worked, and the orphaned tree kangaroo thrived in the pouch of his surrogate rock wallaby mother. The joey, named Makaia, spent about three and a half months in the pouch until being hand-reared by zoo staff.

Millions of spiders fell from the sky and left behind a blanket of silky webs in Goulburn, New South Wales, Australia earlier this week. Although referred to as “baby spiders”, the tiny spiders are actually adult sheet-web weavers or money spiders.
Sometimes these spiders participate in an event called mass ballooning where all the spiders climb to a high point, like up a pole or tall plant, and then they jump into the air to be carried away by air currents. Every time one jumps, it leaves behind a trail of silk strands. The end result is a wispy blanket of spider webs as pictured above.
Did you know that male mice can sing like birds? Their songs are just so high-pitched that humans can’t hear them.
A new study from researchers at Duke University has revealed that male mice will sing loudly to court females they can smell but can’t see. Once the female comes within view, the male will sing more softly.
Cholita, an abused spectacled bear and former circus animal, waits for her trip to the United States, where she can live out the rest of her life in a sanctuary. Photo provided by Animal Defenders International (ADI).
Cholita has had a hard life. She is an Andean/spectacled bear (Tremarctos ornatus), a species considered vulnerable of extinction in the wild. She was kept illegally at a circus in Peru. There, she was severely abused.
Due to the gruesome abuse she suffered at the circus, Cholita now has no claws, teeth or hair. She is barely recognizable as a spectacled bear. But there is hope for Cholita, to live out the rest of her days in a United States sanctuary.
Animal Defenders International (ADI) has worked with the US Fish and Wildlife Service (USFWS) and Peruvian authorities to get Cholita on a special ‘Spirit of Freedom’ flight to Colorado scheduled for April 20. The huge rescue mission, which also includes the rescue of 70 other circus animals, is expected to cost ADI over $1.2 million.
Aww! Busch Gardens Tampa welcomed a pair of cheetah cubs!
A pair of cheetah cubs have joined the ranks at Busch Gardens in Tampa, FL. The cubs, named Tendai and Thabo, weighed 12 pounds when they were born on November 22, 2014. Once old enough, they will start their own coalition of cheetahs at the Cheetah Run habitat.
Dozens of leftover Christmas trees were donated by a local tree lot to the Oakland Zoo after the holiday season wrapped up. And the Oakland Zoo keepers have put them to good use!
“The Christmas trees provide our zoo animals with a unique seasonal enrichment,” said Colleen Kinzley, Director of Animal Care at Oakland Zoo.
The trees became sticky snacks for the giraffes, zebras, camels, elephants, and goats. They provided hiding spots for goodies to entice baboons and otters. And they added a new dimension of fun to the squirrel monkeys’ exhibit.
