The Bronx Zoo introduced the fairy penguins last year after receiving some from the Taronga Zoo in Sydney, Australia. Some fun fairy penguin facts from the Wildlife Conservation Society:
Named 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 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 incubates the egg. Chicks weigh just 25g as hatchlings. They lose their downy plumage at about 50 days of age when it is replaced with waterproof feathers... The species occurs in temperate marine waters and feed 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.
