common name for
members of the large family Columbidae, land birds, cosmopolitan in
temperate and tropical regions, characterized by stout bodies, short
necks, small heads, and thick, heavy plumage. The names dove and pigeon
are used interchangeably, though the former generally refers to smaller
members of the family. All pigeons have soft swellings (ceres) at the
base of the nostrils, feed their young with "pigeon's milk" regurgitated
from the crops of the parents, and have specialized bills through which
they can suck up water steadily, unlike other birds. They eat chiefly
fruits and seeds. From ancient times, pigeons-especially homing pigeons,
which are also used as racing birds-have been used for carrying messages.
Although electronics has largely replaced them as messengers, they are
still of experimental importance. It is thought that they may navigate
by the sun. Monogamous and amorous, pigeons are known for their soft
cooing calls. The most common American wild pigeon is the small, gray-brown
mourning dove Zenaidura macroura (sometimes called turtledove), similar
to the once abundant passenger pigeon, which was slaughtered indiscriminately
and became extinct in 1914. Other wild American species are the band-tailed,
red-billed, and white-crowned pigeons, all of the genus Columba, and
the reddish brown ground-doves (genus Columbina ). The Australasian
region has two thirds of the 289 species of pigeons, of which the fruit
pigeons are the most colorful and the gouras, or crowned pigeons, the
largest (to 33 in./84 cm). In Europe the turtledove, rock pigeon or
dove, stock dove, and ringdove or wood pigeon are common. The rock dove,
Columba livia, of temperate Europe and W Asia is the wild progenitor
of the common street and domestic pigeons. Domesticated varieties developed
by selective breeding include the fantail, with numerous erectile tail
feathers; the Jacobin, with a hoodlike ruff; the tumbler, which turns
backward somersaults in flight; the pouter, with an enormous crop; and
the quarrelsome carrier, with rosettelike eyes and nose wattles. Many
species are valued as game birds; their close relationship to the Gallinae
(e.g., pheasants and turkeys) is illustrated by the sand grouse, an
Old World pigeon named for its resemblance to the grouse. In religion
and art the dove symbolizes peace and gentleness, and in Greek mythology
it was sacred to Aphrodite. The long-extinct dodo and solitaire birds
were members of this order. Pigeons are classified in the phylum Chordata
, subphylum Vertebrata, class Aves, order Columbiformes, family Columbidae.
