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.
House Sparrow
The house sparrow is perhaps the most successful bird in the world at living alongside humans. Introduced to New York in 1851, it spread across North America within decades. Despite its global abundance, house sparrow populations have declined significantly in parts of western Europe.
