Bronx Zoo’s Tree Kangaroo Joey Has Two Birthdays


This Matschie’s tree kangaroo joey at Wildlife Conservation Society’s Bronx Zoo, New York, has two birthdays.


“It was ‘officially’ born on July 4, 2008, and in an embryonic state crawled back into its mother’s pouch to continue developing,” the Zoo said in a news statement. And then there was another celebration, “when the joey was mature enough to brave being outside in the real world to explore and test its climbing abilities.”

Tree kangaroos are found only in the rain forests of Australia, West Papua, and Papua New Guinea. The Matschie’s tree kangaroo (Dendrolagus matschiei) is endemic to the Huon Peninsula on the northeast coast of Papua New Guinea.

The species is classified by the International Union for the Conservation of Nature (IUCN) 2004 Red List as endangered.

The Bronx Zoo’s adult tree kangaroo diet consists of browse, kale, and root vegetables, while the joey’s diet is provided by mom with some “tasting” of solid foods, the zoo said.
