Taronga Zoo's Nocturnal House is home to a Potoroo joey! The joey was first seen sticking its nose out of the pouch by keepers and in mid-July the joey ventured out of mum’s pouch. Keepers estimate the youngster is between 4-5 months old and are yet to find out whether it’s a male or female. Potoroos are in the Macropod family which include kangaroos and wallabies. Potoroos are endangered due to habitat loss and predation by introduced species.
