| Description : |
Distant view of a colony of young Pied Cormorants being encouraged by parent birds to enter the sea from the shores of their rookery on Dangerous Reef, near Port Lincoln. South Australia has populations of the Little Black Cormorant, Little Pied Cormorant, Great Cormorant, Pied Cormorant and the Black-faced Cormorant. Pied cormorants normally inhabit marine environments, but are also attracted to inland waterways. They can dive in both still water and rapidly moving currents and typically are underwater for 40 seconds. The cormorant doesn't have waterproof wings, but this actually helps with its diving prowess: as the wings become water soaked the bird can dive deeper and longer. However the bird then needs to sit on rocks or piles or railings with its wings spread for them to dry. It must also preen its feathers using a special oil gland. |
