Most people are able to identify the basic form of a
pigeon or dove (family : Columbidae), given the ability of some species in
this family to adapt to life in our towns and cities e.g. the Rock Pigeon.
Pigeons are generally plump in body form, with short, strong bills and short
legs. 'Doves' generally refers to species which appear smaller,
more slender and elegant, but the two words are synonymous.
Some of the region's pigeons exhibit handsome colouration, particularly in
males. Females are generally more plain in colour.
Pigeons and doves are strong, but somewhat clumsy, fliers : wing beats are
noisy especially when fleeing rapidly from disturbance.
Their nests comprise a flimsy arrangement of sticks, often only
half-hidden amongst tree branches, though some species favour more
concealed, dense vegetation. In mountainous or coastal areas, some species nest on rock ledges,
and in forested areas some species are mainly terrestrial and nest just
above the ground. Ground-dwellers are particularly vulnerable to predation
from introduced predators such as rats and domestic cats.
Pigeons and doves feed mainly on fleshy seeds : they play an important role
in forest ecology by dispersing, in their faeces, the seeds of fruiting
trees and shrubs, as well as figs.
Pigeons and doves have a near global distribution with around 300 species
being recognised. More than 50 species are likely to occur in Southeast
Asia.

Pink-necked Green Pigeon - male
Treron vernans
Location : Portsdown, Singapore
Habitat : Wooded, residential area.
Fig 2 :
Pink-necked Green Pigeon - female
Treron vernans
Location : Portsdown, Singapore
Habitat : Wooded, residential area.
Fig 3 :
Thick-billed Pigeon - male
Treron curvirostra
Location : Bukit Brown, Singapore
Habitat : Secondary forest in old cemetery.
Notes : Feeding on figs of Ficus microcarpa.
Fig 4 :
Emerald Dove
Chalcophaps indica
Location : Lower Peirce, Singapore
Habitat : Lowland secondary forest
Notes : This is a shy, forest floor species which, when disturbed on trails
or near streams, quietly retreats into the forest without taking flight.
Fig 5 :
Rock Pigeon
Columba livia
Location : Singapore
Habitat : Parkland
Notes : This is the feral descendant of the wild Rock Pigeon : it occurs in towns
and cities throughout the world. It has successfully adapted to the
concrete, high-rise, urban environment because the natural habitat of its
ancestor is one of rock ledges and sea cliffs.
