About These Birds
Andean Teal
A small brown teal with yellow bill and green speculum. Closely related to Yellow-billed Teal; sometimes considered conspecific. Restricted to high-altitude Andean wetlands of Colombia, Ecuador, and Peru. Listed as Near Threatened due to wetland loss.
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.
