The colony of Little Penguins (Eudyptula minor) that debuted in 2015, as a new species at WCS’s (Wildlife Conservation Society) Bronx Zoo, has successfully produced a chick that is now on exhibit with the rest of the colony.

The chick hatched May 10, and this is the first time this species has bred at the Bronx Zoo, in the zoo’s 120-plus year history.

Known for their small size and characteristic bluish hue, Little Penguins are also known as Blue Penguins, Little Blue Penguins, and Fairy Penguins. Adults are only about 13 inches tall and weigh around 2 to 3 pounds. They are the smallest of the 18 penguin species and native to coastal southern Australia and New Zealand.

Little Penguins lay their eggs in burrows dug in sand, natural cavities, or under thick vegetation. They may even nest under man-made structures. Both parents care for and incubate the egg. Newly hatched chicks weigh just 25g. The chicks lose their downy plumage at about 50 days of age when it is replaced with waterproof feathers.

With the exception of the new chick, all of the birds in the Bronx Zoo colony were hatched at the Taronga Zoo in Sydney, Australia and brought to the Bronx Zoo as part of a breeding program. Approximately 15 penguins a year hatch at Taronga, making it the most successful Little Penguin breeding program in the world. The Bronx Zoo penguins will help ensure continued genetic diversity in the Little Penguin populations in the U.S.

The species occurs in temperate marine waters and feeds on fish, cephalopods and crustaceans. They nest, colonially, in burrows on sand dunes or rocky beach areas. Like other penguin species, they use a wide range of vocalizations to communicate with each other. In the wild, their populations are threatened by climate change and human activities.
