The injury on his left leg healed to the point that he was waterproof enough to enjoy a shallow swimming pool. Bro, one of only five Fiordland crested penguins to come into care in the area, was later introduced to a large salt water swimming pool where he began catching his own fish.
A ranger from the National Parks and Wildlife Service gave the thumbs-up and Bro was ready for release.
The yellow-crested, black-and-white penguins grow to about 60cm in height and weigh in at just a few kilograms as adults. Bro was microchipped before his release near Ben Boyd National Park, NSW, on Friday.
