About These Birds
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.
Puna Teal
A medium-sized pale grey teal with a distinctive blue-grey bill, dark cap, and black-and-white back pattern. Restricted to high Andean wetlands. Found in large flocks on puna lakes and salars. Closely related to Silver Teal; sometimes treated as conspecific.
