Bristol Zoo's Lion Twins Make Their Public Debut
Hand-rearing Baby Numbats

Big Day for a Little Joey


The San Francisco Zoological Society is proud to announce the birth of a female Queensland, Koala. This is the first Koala birth at the Zoo since 2000 and the new joey began to emerge from her pouch in January. She will make her first public debut today. San Francisco zookeepers confirmed the birth during a pouch check in December and caught their first glimpse of the bean-sized joey in mid-January. A small hand appeared and over the next few months, little by little, she slowly made her way out of the pouch. It wasn’t until February that the joey made it all the way out and onto her mother’s back.

The birth is part of the Association of Zoos and Aquariums (AZA) Species Survival Plan® (SSP), which strives to manage and conserve species from around the world. The birth mother, Zakary, is on loan from the San Diego Zoo and has been part of the San Francisco Zoo family since 2003. Travis Jr. is the father of the new joey and also comes from San Diego. He arrived in August of 2009 and is here on a breeding recommendation through the AZA SSP.
Koalas are marsupials, “pouched animals,” which means the fetus is undeveloped at birth. Gestation for a baby koala is approximately 35 days and they must find their way into their mother’s pouch and attach to one of two teats. There, they remain hidden for six months before slowly making their way out to see the world. They will start to eat small amounts of “pap” (mother’s stool), which helps prepare their digestive system for the fibrous eucalyptus leaves that make up their entire diet.  Koalas seldom drink water as eucalyptus leaves are made up of 50 percent water.
