How to draw Pigeon for kids - step by step - Fact - Pigeons and doves constitute the bird clade Columbidae, that includes about 310 species.
How to draw Pigeon for kids - step by step - Fact - Pigeons are stout-bodied birds with short necks, and short, slender bills with fleshy ceres. They feed on seeds, fruits, and plants. This family occurs worldwide, but the greatest variety is in the Indomalaya and Australasia ecozones.
How to draw Pigeon for kids - step by step - Fact - In general, the terms "dove" and "pigeon" are used somewhat interchangeably. Pigeon is a French word that derives from the Latin pipio, for a "peeping" chick, while dove is a Germanic word that refers to the bird's diving flight.
How to draw Pigeon for kids - step by step - Fact - In ornithological practice, "dove" tends to be used for smaller species and "pigeon" for larger ones, but this is in no way consistently applied, and historically, the common names for these birds involve a great deal of variation between the terms. The species most commonly referred to as "pigeon" is the feral rock pigeon, common in many cities.
How to draw Pigeon for kids - step by step - Fact - Doves and pigeons build relatively flimsy nests – often using sticks and other debris – which may be placed in trees, on ledges, or on the ground, depending on species. They lay one or two eggs at a time, and both parents care for the young, which leave the nest after seven to twenty-eight days.
How to draw Pigeon for kids - step by step - Fact - 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. Young doves and pigeons are called "squabs".
How to draw Pigeon for kids - step by step - Fact - The Pteroclididae (sandgrouse) were formerly included in the order Columbiformes largely due to their reported ability to drink by the "sucking" or "pumping" action of peristalsis of the esophagus ("The only other group, however, which shows the same behaviour, the Pteroclididae, is placed near the doves just by this doubtlessly very old characteristic." ); more recently,
How to draw Pigeon for kids - step by step - Fact - it had been reported that they cannot drink by "sucking" or "pumping", and were treated separately in the order Pteroclidiformes and were considered to be closer to the shorebirds. Recent phylogenomic studies support the grouping of these pigeons and sangrouse together, along with mesites, forming the sister taxon to Mirandornithes.
How to draw Pigeon easy - step by step - Fact - Columbidae are usually divided into five subfamilies, probably inaccurately. For example the American ground and quail doves, which are usually placed in the Columbinae, seem to be two distinct subfamilies. The order presented here follows Baptista et al. (1997) with some updates.
How to draw Pigeon easy - step by step - Fact - Osteology and DNA sequence analyses indicate the dodo and Rodrigues solitaire are better considered as a subfamily Raphinae in the Columbidae pending availability of further information.
How to draw Pigeon for Beginners - Fact - The arrangement of genera and naming of subfamilies is in some cases provisional, because analysis of different DNA sequences yield results that differ, often radically, in the placement of certain (mainly Indo-Australian) genera.
How to draw Pigeon for Beginners - Fact - This ambiguity, probably caused by long branch attraction, seems to confirm the first pigeons evolved in the Australasian region, and that the "Treronidae" and allied forms (crowned and pheasant pigeons, for example) represent the earliest radiation of the group.
How to draw Pigeon for Children - Fact - The dodo and Rodrigues solitaire are in all likelihood part of the Indo-Australian radiation that produced the three small subfamilies mentioned above, with the fruit-doves and pigeons (including the Nicobar pigeon). Therefore, they are here included as a subfamily Raphinae, pending better material evidence of their exact relationships.
