Zebra
Doves are the smallest of the terrestrial doves found in Singapore.
They feed on grass seeds, preferring to forage on bare ground or short
grass, scurrying about with rodent-like movement. Unlike other doves,
they forage alone, or in pairs. Their coloration camouflages them
wonderfully against the ground.
They
are more shy than the Spotted Dove and fly off into nearby undergrowth
at the first sign of danger.
They appear to prefer open areas including cultivated parks, gardens
and even in urban areas. They are also found in mangroves.
Zebra Doves roost at night high in trees and seem particularly fond
of roosting in coconut palms.

Pigeons
and doves do not have well-developed oil glands, which in other birds are
used to waterproof their feathers. Instead, they have special plumes scattered
throughout their body which disintegrate to produce a powder which cleans
and lubricates the feathers.
Breeding:
Zebra Doves breed in September to June. Zebra Dove males have a courtship
display of brisk bobbing with head down and tail up, while loudly
calling. They do this on a high perch, facing the female. As the pair
sit side-by-side, he may sing.
Like other pigeons, the Zebra Dove nest is a flimsy platform of twigs
and fibres, usually in a small tree, palm and sometimes in a bush.
1-2 white eggs are laid.
Migration: Although Zebra Doves
may disperse widely to look for food or escape harassment, they are
not migratory. Being a popular cage bird, they are introduced to many
areas they were not native to.

Pigeon's
Milk
The
most fascinating feature of pigeons and doves is their ability to
produce crop milk. During breeding season, special glands in the crops
of both males and females enlarge and secrete a thick milky substance.
The chicks drink this milk by poking their bills into the parent's
throat.
Thus, pigeons and doves can feed their young without having to incessantly
hunt or forage for food. Instead of laying many eggs, they lay one
or at most two eggs. Their abundance is proof that this feature gives
them the advantage. |
Status
and threats: Zebra Doves adapt well to cultivated area and quickly
spread to such places. Popular in bird-singing contests, wild Zebra Doves
are often heavily trapped for sale as cage birds. Nevertheless, they are
still common and not considered at risk in Singapore.
