Columbidae

The doves are the 308 species of near passerine birds in the order Columbiformes. The terms dove and pigeon are used interchangeably, although smaller species are more likely to be called doves.

Pigeons and doves are stout-bodied birds with short necks and short slender bills with a fleshy cere.

The poorly constructed nests are made of sticks, and the two white eggs are incubated by both sexes. Doves feed on seeds, fruit and other soft plantstuffs. Unlike most other birds, (but see flamingo), the doves and pigeons produce "crop milk", which is secreted by a sloughing of fluid-filled cells from the lining of the crop. Both sexes produce this highly nutritious substance to feed to the young.

This family occurs worldwide, but the greatest variety is in the Indomalaya and Australasia ecozones.
