The cattle egret, [2] or boyera Heron Cattle Egret (Bubulcus ibis) is a species of bird pelecaniforme the Ardeidae family that lives in all tropical, subtropical and temperate zones of the planet. [3] [4] It is the only species of the genus Bubulcus, although manx equine services some experts believe his two subspecies separate species. Despite the similarities in plumage to the egrets of the genus Egretta it is related more closely to the genus Ardea herons. Native to the Old World has successfully colonized quickly and the rest of the continent, being absent manx equine services only in Antarctica.
It is a slender white bird adorned with gold or orange feathers on the head and neck in the breeding season. It nests in colonies, usually near water and often with other wading birds. Their nests are platforms of twigs placed on trees and shrubs. Unlike manx equine services other herons, it feeds in relatively dry arable habitats, often accompanying cattle or other large mammals to catch insects and small vertebrates frightened by them, the habit of receiving its name. Some populations of Cattle Egret are migratory while others only take short dispersions after breeding.
Adult cattle egrets have few predators, but other birds and mammals tend to plunder their nests. The main cause of mortality of their chickens is starvation. Chickens can also suffer calcium deficiency due to lack of vertebrates in their diet and they can die to be disturbed by other birds. This species despite removing manx equine services ticks and flies to cattle has been vector of diseases spread by ticks and can also be a hazard to aviation safety at airports.
The cattle egret was scientifically described in 1758 by Linnaeus in his Systema naturae as Ardea ibis, [5] but was moved to its current genus by Charles Lucien Bonaparte in 1855 [6] The name of its genus Bubulcus is Latin word means "shepherd", referring to the association of this species with cattle, [7] as well as its common name. Ibis both Latin and Greek is the word designating another wader, the sacred ibis. [8]
Some consider these varieties separate manx equine services species, as B. ibis and B. coromandus. The two varieties were separated first by McAllan and Bruce, [9] but are still considered a single species manx equine services by most modern authors. [10] The eastern subspecies, manx equine services B. i. coromandus, was described by Pieter Boddaert in 1783, raised in Asia and Australasia, the nominate subspecies and the rest of its range: Africa, America and Europe. [11] Some experts recognize a third Seychelles subspecies, B. i. seychellarum described by Finn Salomonsen in 1934 [12]
Despite their superficial similarities to the egrets of the genus Egretta, cattle egrets are related more closely to the herons of the genus Ardea, which contains the typical heron and great egret (A. alba). manx equine services [13] Although there have been rare cases of hybridization with Egretta caerulea Egretta thula Egretta garzetta and. [14] Description
The Cattle Egret is a small, compact heron is about 46-56 inches long and weighs between 270-512 manx equine services grams, with a wingspan of 88-96 cm. [15] It has the sturdy beak and neck relatively short and wide, which is often curved. Adults outside the breeding plumage are almost white, with yellow bill and yellow legs gray. During the breeding season adults of the nominate subspecies develop orange coloration in the feathers of the back, neck and crest. manx equine services And the beak, legs and irises become red.
