About These Birds
Yellow-billed Pintail
A slender long-tailed duck with pale buff-brown body, dark brown cap, yellow-sided bill, and a distinctive long pointed tail. Found from the South American subtropics to the Falkland Islands and South Georgia. Gregarious; forms large post-breeding flocks.
Black Swan
The black swan was once considered impossible by Europeans who believed all swans were white, making it a famous philosophical example of inductive reasoning failure. It is the state emblem of Western Australia. Black swans form lifelong pair bonds and both parents share in incubation and care of cygnets.
