Birds
Australia and its territories are home to around 800 species of bird; about 350 of these are endemic to the zoogeographic region that covers Australia, New Guinea and New Zealand. The fossil record of birds in Australia is patchy; however, there are records of the ancestors of contemporary species as early as the Late Oligocene. Birds with a Gondwanan history include the flightless ratites (the Emu and Southern Cassowary), megapodes (the Malleefowl and Australian Brush-turkey), and a huge group of endemic parrots, order Psittaciformes. Australian parrots comprise a sixth of the world's parrots, including many cockatoos and galahs. The Kookaburra is the largest species of the kingfisher family, known for its call, which sounds uncannily like loud, echoing human laughter.
The passerines of Australia, also known as songbirds or perching birds, include wrens, robins, the magpie group, thornbills, pardalotes, the huge honeyeater family, treecreepers, lyrebirds, Birds of Paradise and bowerbirds. The Satin Bowerbird has attracted the interest of evolutionary psychologists; it has a complex courtship ritual in which the male creates a bower filled with blue, shiny items to woo mates.
Relatively recent colonists from Eurasia are swallows, larks, thrushes, cisticolas, sunbirds, and some raptors, including the large Wedge-tailed Eagle. A number of bird species have been introduced by humans; some, like the European Goldfinch and Greenfinch, coexist happily with Australian species, while others, such as the Common Starling, Common Blackbird, House Sparrow and Indian Mynah, are destructive of some native bird species and thus destabilise the native ecosystem.
About 200 species of seabird live on the Australian coast, including many species of migratory seabird. Australia is at the southern end of the East Asian-Australasian flyway for migratory water birds, which extends from Far-East Russia and Alaska through Southeast Asia to Australia and New Zealand. About two million birds travel this route to and from Australia each year. One very common large seabird is the Australian Pelican, which can be found in most waterways in Australia. The Little Penguin is the only species of penguin that breeds on mainland Australia.

Famous quotes containing the word birds:
“... to a poet, the human community is like the community of birds to a bird, singing to each other. Love is one of the reasons we are singing to one another, love of language itself, love of sound, love of singing itself, and love of the other birds.”
—Sharon Olds (b. 1942)
“The sun descending in the west,
The evening star does shine;
The birds are silent in their nest,
And I must seek for mine.”
—William Blake (1757–1827)
“When you have shot one bird flying you have shot all birds flying. They are all different and they fly in different ways but the sensation is the same and the last one is as good as the first.”
—Ernest Hemingway (1899–1961)
