Two Bilby joeys were born at Perth Zoo in April 2012. The twins, both females, spent around 73 days developing in the safety of their mother’s pouch before she deposited them in the burrow in their exhibit in June. They weighed 242g each at that stage. Once deposited in the burrow, they soon began venturing outside of the burrow. This is the second year in a row Perth Zoo has bred Bilbies. Perth Zoo’s breeding program is part of regional recovery efforts to safeguard the Bilby from extinction. Major threats to the Bilby include foxes and cats, competition from rabbits, and habitat loss.
