Nature and Trees Bird - Cattle Egrets
Показать описание
This is another video of mine filmed during my holidays. When I was travelling in the countryside I saw a flock of Cattle Egrets at two places on a paddy field being ploughed by a hand tractor.This was for them to eat the insects thrown out and it was such an eye catching scenary. So I stopped the vehicle and I filmed from it as this was such an eye catching scenary. I couldnt believe my eyes to see so many Cattle Egrets. It seems that the ploughing is not an easy task. It is a wonder that they are still full white from such a mud splashing tractor :))
Cattle Egret
==========
The Cattle Egret (Bubulcus ibis) is a cosmopolitan species of heron (family Ardeidae) found in the tropics, subtropics and warm temperate zones.Originally native to parts of Asia, Africa and Europe.
It is a white bird adorned with buff plumes in the breeding season. It nests in colonies, usually near bodies of water and often with other wading birds. The nest is a platform of sticks in trees or shrubs. Cattle Egrets exploit drier and open habitats more than other heron species. Their feeding habitats include seasonally inundated grasslands, pastures, farmlands, wetlands and rice paddies. They often accompany cattle or other large mammals, catching insect and small vertebrate prey disturbed by these animals.
The Cattle Egret is a stocky heron with a 88--96 cm wingspan.It has a relatively short thick neck, sturdy bill, and a hunched posture. The positioning of the egret's eyes allows for binocular vision during feeding, and physiological studies suggest that the species may be capable of crepuscular or nocturnal activity. Adapted to foraging on land, they have lost the ability possessed by their wetland relatives to accurately correct for light refraction by water.
The Cattle Egret has undergone one of the most rapid and wide reaching natural expansions of any bird species.
Some populations of Cattle Egrets are migratory, others are dispersive, and distinguishing between the two can be difficult for this species. In many areas populations can be both sedentary and migratory.
During winter, many birds have been seen flying at night with flocks of Indian Pond Herons. on the southeastern coast of India and a winter influx has also been noted in Sri Lanka.
The Cattle Egret nests in colonies, which are often, but not always, found around bodies of water. The colonies are usually found in woodlands near lakes or rivers, in swamps, or on small inland or coastal islands, and are sometimes shared with other wetland birds, such as herons, egrets, ibises and cormorants. The breeding season varies within South Asia.
The male displays in a tree in the colony, using a range of ritualised behaviours such as shaking a twig and sky-pointing and the pair forms over three or four days. A new mate is chosen in each season and when re-nesting following nest failure.The clutch size can be anywhere from one to five eggs.
The Cattle Egret feeds on a wide range of prey, particularly insects, especially grasshoppers, crickets, flie and moths, as well as spiders, frogs, and earthworms. The species is usually found with cattle and other large grazing and browsing animals, and catches small creatures disturbed by the mammals.
A Cattle Egret will weakly defend the area around a grazing animal against others of the same species, but if the area is swamped by egrets it will give up and continue foraging elsewhere. Where numerous large animals are present, Cattle Egrets selectively forage around species that move at around 5--15 steps per minute, avoiding faster and slower moving herds.
