Pigeons & Doves
   
   

Fig 1

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.

Fig 3 :
Emerald Dove
Chalcophaps indica

Fig 6 :
Rock Pigeon
Columba livia
Habitat : Parkland
Location : Singapore
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.
