Busch Gardens Tampa welcomed a female southern white rhinoceros calf on October 16. The calf is healthy and is currently being cared for by experienced mother Kisiri with the Busch Gardens animal care team watching closely.

Newborn white rhinoceroses usually weigh about 150 pounds and can gain four pounds every day for the first year. White rhinos are the second largest land mammal after the elephant and can weigh as much as 5,000 pounds when fully grown.
The southern white rhinoceros is classified as a near-threatened species with just over 20,000 left in the wild, according to the International Union for Conservation of Nature and Natural Resources (IUCN).
The Toronto Zoo is pleased to announce that Makali, a four-year-old white lioness, gave birth to four cubs on September 26-27.
The little lion cubs are healthy, feeding well, and staying in the maternity area of the lion habitat at the zoo. The first thirty days will be critical for the cubs and zoo staff will continue to monitor them closely.
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.
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.

The amazing rescue story of Makaia will be featured in the July/August edition of Australian Geographic, available July 3.
