In a release Friday, the Bronx Zoo announced that a Matschie's tree kangaroo born at the zoo several months ago is starting to emerge from its mother's pouch to make "its anticipated public debut." The marsupial baby is the first of its species to be born at the zoo since 2008. While zoogoers are just now getting a peek at the joey's tiny face, that is not the baby kangaroo's first few days of life. According to the Bronx Zoo, a tree kangaroo is about the size of a human thumbnail at birth. After entering the world, the newborn immediately crawls through its mother's fur to enter her pouch. A majority of tree kangaroo's physical development occurs in their mother's pouch. After about seven months in the pouch, a tree kangaroo joey starts to emerge and peek out at the world.

"At this stage of development, the joey will spend a lot of time in his mom's pouch with just its head sticking out. As it matures, it will begin to explore its environment and start spending short periods of time outside the pouch." The International Union for Conservation of Nature (IUCN) classifies the Matschie's tree kangaroo, native to Papua New Guinea, as endangered. It is estimated that fewer than 2,500 remain in the wild.

The program works to match individual animals across AZA-accredited zoos and aquariums for breeding to "maintain genetic diversity and demographic stability in zoo populations."
