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.
European Goldfinch
The European goldfinch is a strikingly beautiful finch whose tinkling song and colorful plumage have made it popular in art and as a caged bird for centuries. It appears frequently in Renaissance paintings as a symbol of the Passion of Christ. Flocks of goldfinches are charmingly called a charm.
