Columbidae is a fledgling family containing the pigeons and birds. It is the principal family in the solicitation of Columbiformes. These are heftily bodied flying creatures with short necks, and short slim bills that in certain species highlight plump ceres.
They principally feed on seeds, organic products, and plants. The family happens around the world, yet the best assortment is in the Indomalaya and Australasia ecozones.
The family contains 344 species separated into 49 genera. Thirteen of the species are wiped out. In English, the littler species will, in general, be classified “dove” and the bigger ones “pigeon”.
The qualification isn’t steady, while dove is a Germanic word that alludes to the winged creature’s plunging flight. The English regional word “culver” seems to get from Latin Columba.
Birds and pigeons manufacture generally shaky homes, regularly utilizing sticks and different trash, which might be put on trees, edges, or the ground, contingent upon species.
They lay each or two eggs thusly, and the two gatekeepers care for the youthful, which leave the home following 7–28 days.
In contrast to most feathered creatures, both genders of birds and pigeons produce “crop milk” to deal with their young, discharged by sloughing of fluid-filled cells from the coating of the harvest. Youthful birds and pigeons are classified “squabs”.
Scientific classification and systematics
The family Columbidae was presented by the English zoologist William Elford Leach in a manual for the substance of the British Museum distributed in 1820.
Columbidae is the main living family in the request of Columbiformes.
The sandgrouses were once in the past put here, however, they were moved to a different request Pterocliformes dependent on anatomical contrasts; they are presently viewed as more firmly identified with shorebirds.
Late phylogenomic contemplates bolstering the gathering of pigeons and sandgrouse together, alongside mesites, framing the sister taxon to Mirandornithes.
The Columbidae are normally partitioned into five subfamilies, presumably erroneously. For instance, the American ground and quail pigeons, which are generally set in the Columbine, appear to be two particular subfamilies.
The request introduced here follows Baptista et al., with certain updates. The course of action of genera and naming of subfamilies is now and again temporary since examinations of various DNA groupings yield results that vary, frequently fundamentally, in the situation of specific genera.
This uncertainty, most likely brought about by long branch fascination, appears to affirm the primary pigeons advanced in the Australasian locale, and that the “Treronidae” and unified structures speak to the soonest radiation of the gathering.
The family Columbidae beforehand likewise contained the family Raphidae, comprising of the wiped out Rodrigues solitaire and the dodo. These species are a more than likely piece of the Indo-Australian radiation that created the three little subfamilies referenced above, with the natural product birds and pigeons. Consequently, they are here included as a subfamily Raphinae, pending better material proof of their accurate connections.
Intensifying these issues, columbids are not very much spoken to in the fossil record. No genuinely crude structures have been found to date.
The variety of Grandia has been portrayed from Early Miocene stores in France, however, while it was for quite some time accepted to be a pigeon, it is currently viewed as a sandgrouse.
Fragmentary survives from a presumably “philippine” Early Miocene pigeon were found in the Bannockburn Formation of New Zealand and portrayed as Rupephaps; Apart from that, every other fossil has a place with surviving genera.
