Reproduction: The nest which is a flimsy platform of sticks is constructed in
trees, in holes in trees, on building lodges, or on the ground. The clutch size is
one to three pure glossy white eggs. Eggs may be yellow to buff in colour in some tropical members. Both sexes incubate eggs. Young are fed on 'pigeon milk'
by regurgitation. The pigeon milk is secreted by special cell lining the crop of a
pigeon. The cheesy milk is gradually replaced by the partially digested food
materials. If eggs or young are lost, she will lay again. Two to three or more
broods may occur annually. Young leave the nest when they are about 15-21 days
Behaviour: The majority members are gregarious. Some pigeons are migratory in nature. Fruits pigeons live almost in trees. Pigeons are used as pet and laboratory birds. A pigeon is trained to carry massages tied to it neck or leg. Life span: Pigeons can live 22 to 25 years in the wild state.
