These are commonly known as the topknot pigeon but are a different species, they are native to Australia and are widespread throughout most of the mainland except for denser forests. Their habitat has expanded since European settlement which has produced extensive pastoral lands that are ideal for seed eating birds. Their natural habitat is grasslands and lightly wooded areas but they have adapted well to suburban areas and here you see them in streets, parks, gardens, pastoral areas, sports grounds, and golf courses.
If startled this pigeon takes to the air with a characteristic whistling flight, this whistling sound is produced by air passing over a modified primary feather on the wing.
Their diet consists mostly of native seeds as well as those of introduced crops and weeds, some leaves and insects are also eaten.
While they breed throughout the year it is more common in the warmer months, mating begins with an elaborate dance by the male who accompanies it with soft hooting. A delicate nest of twigs is built in a tree or dense bush and two eggs are laid, both parents incubate the eggs and care for the young.
