| Ocyphaps lophotes (Temminck, 1822) |
The Crested Pigeon (Ocyphaps lophotes) is a bird found widely throughout mainland Australia except for far tropical north areas. There are only two Australian pigeon species that possess an erect crest, being the Crested Pigeon and the Spinifex Pigeon. The Crested Pigeon is the larger of the two species.

[edit] Description
The length of the Crested Pigeon varies from 30 to 34 centimetres (12 to 13.6 inches). Colouration is grey with tinges of brown. It has a feathered but slender, black spike on top of head. They run with the crest erect. There is a bright orange ring around each of its eyes. Wings have black stripings and are bronzed, while the primary feathers have colourful areas of brown, purple, blue and green. Immature birds have duller colours with no bronzing on the wings.
The call is a "whoop"! voiced repeatedly but singly when alarmed.
[edit] Distribution and habitat
Habitat is grasslands, brush and wooded areas but they can also be seen at watercourses, homestead gardens, pastoral areas, sports grounds, and golf courses. Their habitat has expanded since settlement has produced pastoral lands (previously they were only found in inland and Western Australia). Foraging for grain, has adapted to grain farming areas, often feeding on the noxious weed of Salvation Jane. They are commonly known by the misnomer of "Topknot" pigeon, however the Topknot Pigeon is in fact a different species, Lopholaimus antarcticus.
[edit] Behaviour
Their most distinctive behaviour is the beating and whistling sound their wings make when they take off. This is most likely to draw the attention of predators to birds on the wing, and away from any birds remaining on the ground. When the birds land, the tail tilts upwards and the flight patterns are similar to the those of the Spotted Turtle-Dove. They are generally sedentary. Although can be seen in pairs but they can be highly social and tend to be seen in packs. They are highly gregarious birds when in contact with humans.
[edit] Breeding
While they breed throughout the year, it is more common in the warmer months. Nesting usually occurs in shrubs or trees. Nests usually consist of a platform of twigs. They lay two oval, white and glossy eggs.
