Male Pigeons Fly Down To His Wife on a Shopping Street , The many other Old World genera in the subfamily Columbinae include the chicken-sized pheasant pigeon (Otidiphaps nobilis) of New Guinea. In the New World the white-winged doves and the mourning dove (Zenaida) are popular game birds; Central and South America support the terrestrial ground doves (Metriopelia) and quail doves (Geotrygon). The New World passenger pigeon is extinct.

The Treroninae, or the fruit pigeons, consists of about 115 species in about 10 genera, found primarily in Africa, southern Asia, Australia, and the Pacific islands. These fruit-eating birds are soft-billed, short-legged, and arboreal in habit. Their plumage is usually greenish, often with yellow, red, or other brightly coloured markings. The group includes the heavyset imperial pigeons (Ducula); the small and extremely colourful fruit doves (Ptilinopus); the blue pigeons (Alectroenas), dark blue in colour with red wattles; and the usually crimson-legged green pigeons (Treron).

The Gourinae, or crowned pigeons, consists solely of three species (genus Goura), found in New Guinea. Blue-gray birds with fanlike head crests, they are the largest of all pigeons—nearly the size of a turkey.

The Didunculinae consists of a single species, the tooth-billed pigeon (Didunculus strigirostris), which is native to Samoa. This fruit-eating, terrestrial pigeon has adopted arboreal ways in response to near extermination by introduced predators. Unlike most pigeons, it uses its feet to hold down its food while pecking off pieces.
