Woodland Park Zoo's Matschie’s Tree Kangaroo joey is growing up fast, so here are some new photos and video to fill you in on how it is getting along in its behind-the-scenes exhibit. Now eight months old, the joey has begun to leave its mother’s pouch for short bursts, doing a little exploring and then retreating back to the pouch for naps. Keepers do not know the sex of the joey yet so for now he or she remains nameless. The joey is mostly eating leaves but also munches on greens including kale, romaine and celery. Mother "Elanna" is not so great at sharing, so the joey has learned to go after the food it wants for itself.

Elanna and joey are in a behind the scenes exhibit to give them the quiet and comfort this sensitive species requires, especially since Elanna is a first time mother. The Woodland Park Zoo is using cameras and students are assisting with observations so they can study the interactions between the mother and joey and keep a close eye on their progress.
