Trinka, an endangered Parma Wallaby joey, is being hand raised at the San Diego Zoo nursery. Her name is an Australian aboriginal word for daytime. She's small but strong, and her keepers describe her as sweet and expressive. She was found on the ground outside her mother's pouch when she was very small and had to be hand raised at the San Diego Zoo nursery. She was given a faux "pouch" to snuggle into and she comes out of it for a little exercise during the day. Feeding small babies like Trinka can be difficult, but the San Diego Zoo keepers are experts, and Trinka is doing great finishing off her four bottles a day.
