Columbimorphae
Columbimorphae is a clade discovered by genome analysis that includes birds of the orders Columbiformes (pigeons and doves), Pterocliformes Sandgrouse is the common name for Pteroclidae , a family (biology), family of sixteen species of bird, members of the order Pterocliformes . They are traditionally placed in two Genus, genera. The two central Asian species are classified as ''Sy ... (sandgrouse), and Mesitornithiformes (mesites). Previous analyses had also recovered this grouping, although the exact relationships differed. Some studies indicated a sister relationship between sandgrouse and pigeons (the traditional view) while other studies favored a sister grouping of mesites and sandgrouse instead.

Pterocliformes
Sandgrouse is the common name for Pteroclidae , a family of sixteen species of bird, members of the order Pterocliformes . They are traditionally placed in two genera. The two central Asian species are classified as '' Syrrhaptes'' and the other fourteen species, from Africa and Asia, are placed in the genus ''Pterocles''. They are ground dwelling birds restricted to treeless, open country, such as plains, savannahs, and semi-deserts. They are distributed across northern, southern, and eastern Africa, Madagascar, the Middle East, and India through central Asia. The ranges of the black-bellied sandgrouse and the pin-tailed sandgrouse even extend into the Iberian Peninsula and France, and Pallas's sandgrouse occasionally breaks out in large numbers from its normal range in Asia. Description Sandgrouse have small, pigeon-like heads and necks and sturdy compact bodies. They range in size from in length and from in weight. The adults are sexually dimorphic with the males being s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pterocles Alchata
The pin-tailed sandgrouse (''Pterocles alchata'') is a medium large bird in the sandgrouse family. It has a small, pigeon like head and neck and a sturdy, compact body. It has long pointed wings, which are white underneath, a long tail and a fast direct flight. Flocks fly to watering holes at dawn. The call is a loud ''kattar-kattar''. This gregarious species breeds on dry open treeless plains and similar habitats. Its nest is a ground scrape into which two or three cream-coloured eggs with cryptic markings are laid. Both sexes incubate the eggs. The pin-tailed sandgrouse is about long. Its head and upperparts are yellowish-green. The underparts are white with a chestnut breast band separating the belly from the green neck. Sexes are somewhat similar, but the female is better camouflaged and has a shorter tail than the male. There are two subspecies; ''P. a. alchata'' breeds in southern Europe and ''P. a. caudacutus'' breeds in northwestern Africa, the Middle East and southeaster ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Columbiformes
Columbidae () is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms. The family contains 344 species divided into 50 genera. Thirteen of the species are extinct. In English, the smaller species tend to be called "doves" and the larger ones "pigeons". However, the distinction is not consistent, and does not exist in most other languages. Historically, the common names for these birds involve a great deal of variation between the terms. The bird most commonly referred to as just "pigeon" is the domestic pigeon, which is common in many cities as the feral pigeon. Doves and pigeons build relatively flimsy nests, often using sticks and other debris, which may be placed on bran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Columba Livia In Japan White Background
Columba or Colmcille; gd, Calum Cille; gv, Colum Keeilley; non, Kolban or at least partly reinterpreted as (7 December 521 – 9 June 597 AD) was an Irish abbot and missionary evangelist credited with spreading Christianity in what is today Scotland at the start of the Hiberno-Scottish mission. He founded the important abbey on Iona, which became a dominant religious and political institution in the region for centuries. He is the patron saint of Derry. He was highly regarded by both the Gaels of Dál Riata and the Picts, and is remembered today as a Catholic saint and one of the Twelve Apostles of Ireland. Columba studied under some of Ireland's most prominent church figures and founded several monasteries in the country. Around 563 AD he and his twelve companions crossed to Dunaverty near Southend, Argyll, in Kintyre before settling in Iona in Scotland, then part of the Ulster kingdom of Dál Riata, where they founded a new abbey as a base for spreading Celtic Christianit ...
