Passenger pigeon wiki8/10/2023 ![]() ![]() The arrangement of genera and naming of subfamilies is in some cases provisional because analyses of different DNA sequences yield results that differ, often radically, in the placement of certain (mainly Indo-Australian) genera. The order presented here follows Baptista et al. For example, the American ground and quail doves ( Geotrygon), which are usually placed in the Columbinae, seem to be two distinct subfamilies. The Columbidae are usually divided into five subfamilies, probably inaccurately. The sandgrouse (Pteroclidae) were formerly placed here, but were moved to a separate order, Pterocliformes, based on anatomical differences (such as the inability to drink by "sucking" or "pumping"). Columbidae is the only living family in the order Columbiformes. The name 'Columbidae' for the family was introduced by the English zoologist William Elford Leach in a guide to the contents of the British Museum published in 1820. See also: List of Columbidae genera and List of Columbidae species Whole genome analyses have found the columbiformes form a sister clade of a group conformed by the sandgrouses ( Pterocliformes) and mesites ( Mesitornithiformes). ![]() Origin and evolutionĬolumbiformes is one of the most diverse non- passerine clades of neoavians, and its origins are in the Cretaceous and the result of a rapid diversification at the end of the K-Pg boundary. A group of doves is called a "dule", taken from the French word deuil ('mourning'). The English dialectal word culver appears to derive from Latin columba. Pigeon is a French word that derives from the Latin pīpiō, for a "peeping" chick, while dove is an ultimately Germanic word that refers to the bird's diving flight. Unlike most birds, both sexes of doves and pigeons produce " crop milk" to feed to their young, secreted by a sloughing of fluid-filled cells from the lining of the crop. These fledglings, with their immature squeaking voices, are called squeakers once they are weaned. Unfledged baby doves and pigeons are called squabs and are generally able to fly by 5 weeks of age. They lay one or (usually) two white eggs at a time, and both parents care for the young, which leave the nest after 25–32 days. The bird most commonly referred to as just "pigeon" is the domestic pigeon, which is common in many cities as the feral pigeon.ĭoves and pigeons build relatively flimsy nests, often using sticks and other debris, which may be placed on branches of trees, on ledges, or on the ground, depending on species. Historically, the common names for these birds involve a great deal of variation among the terms. However, the distinction is not consistent, and does not exist in most other languages. In English, the smaller species tend to be called "doves" and the larger ones "pigeons". The family contains 344 species divided into 50 genera. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms. They primarily feed on seeds, fruits, and plants. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. It is the only family in the order Columbiformes. ![]() Geographic range of the family ColumbidaeĬolumbidae ( / k ə ˈ l ʌ m b ɪ d iː/) is a bird family consisting of doves and pigeons. ![]()
