Egret
Egrets ( ) are herons, generally long-legged wading birds, that have white or buff plumage, developing fine plumes (usually milky white) during the breeding season. Egrets are not a biologically distinct group from herons and have the same build. Biology Many egrets are members of the genera '' Egretta'' or '' Ardea'', which also contain other species named as herons rather than egrets. The distinction between a heron and an egret is rather vague, and depends more on appearance than biology. The word "egret" comes from the French word ''aigrette'' that means both "silver heron" and "brush", referring to the long, filamentous feathers that seem to cascade down an egret's back during the breeding season (also called "egrets"). Several of the egrets have been reclassified from one genus to another in recent years; the great egret, for example, has been classified as a member of either ''Casmerodius'', ''Egretta'', or ''Ardea''. In the 19th and early part of the 20th centuries, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cattle Egret
The cattle egret (''Bubulcus ibis'') is a cosmopolitan species of heron (family Ardeidae) found in the tropics, subtropics, and warm-temperate zones. It is the only member of the monotypic genus ''Bubulcus'', although some authorities regard its two subspecies as full species, the western cattle egret and the eastern cattle egret. Despite the similarities in plumage to the egrets of the genus '' Egretta'', it is more closely related to the herons of '' Ardea''. Originally native to parts of Asia, Africa, and Europe, it has undergone a rapid expansion in its distribution and successfully colonised much of the rest of the world in the last century. 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 inunda ...

Great Egret
The great egret (''Ardea alba''), also known as the common egret, large egret, or (in the Old World) great white egret or great white heron is a large, widely distributed egret. The four subspecies are found in Asia, Africa, the Americas, and southern Europe. Recently it is also spreading to more northern areas of Europe. Distributed across most of the tropical and warmer temperate regions of the world, it builds tree nests in colonies close to water. Taxonomy and systematics Like all egrets, it is a member of the heron family, Ardeidae. Traditionally classified with the storks in the Ciconiiformes, the Ardeidae are closer relatives of pelicans and belong in the Pelecaniformes, instead. The great egret—unlike the typical egrets—does not belong to the genus '' Egretta'', but together with the great herons is today placed in '' Ardea''. In the past, however, it was sometimes placed in ''Egretta'' or separated in a monotypic genus ''Casmerodius''. The Old World population ...

Snowy Egret
The snowy egret (''Egretta thula'') is a small white heron. The genus name comes from Provençal French for the little egret, , which is a diminutive of , 'heron'. The species name ''thula'' is the Araucano term for the black-necked swan, applied to this species in error by Chilean naturalist Juan Ignacio Molina in 1782.Jobling, 2010, p.143, 385 The snowy egret is the American counterpart to the very similar Old World little egret, which has become established in the Bahamas. At one time, the plumes of the snowy egret were in great demand as decorations for women's hats. They were hunted for these plumes and this reduced the population of the species to dangerously low levels. Now protected in the United States by law, under the Migratory Bird Treaty Act, this bird's population has rebounded. Description Adult snowy egrets are entirely white apart from the yellow lores between the long black bill and the eye, black legs, and bright yellow feet. The nape and neck bear lo ...

Western Reef Heron
The western reef heron (''Egretta gularis''), also called the western reef egret, is a medium-sized heron found in southern Europe, Africa and parts of Asia. It has a mainly coastal distribution and occurs in several plumage forms: a slaty-grey plumage in which it can only be confused with the rather uncommon dark morph of the Little egret (''Egretta garzetta''); a white form which can look very similar to the little egret although the bill tends to be paler and larger and the black form with white throat ''E. g. gularis'' of West Africa. There are also differences in size, structure and foraging behaviour. There have been suggestions that the species hybridizes with the Little Egret, and based on this, some authors treat ''schistacea'' and ''gularis'' as subspecies of ''Egretta garzetta''. Works that consider the Western Reef Heron as a valid species include the nominate ''gularis'' and ''schistacea'' as subspecies. Description This bird has two plumage colour forms. There ...

Reddish Egret
The reddish egret (''Egretta rufescens'') is a medium-sized heron that is a resident breeder in Central America, The Bahamas, the Caribbean, the Gulf Coast of the United States (primarily Texas), and Mexico. The egret is known for its unusual foraging behavior compared to other herons as well as its association with mud flats, its habitat of choice. In the past, this bird was a victim of the plume trade and is North America’s "rarest and least studied ardeid." Taxonomy The reddish egret was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's '' Systema Naturae''. He placed it with the herons, cranes and egrets in the genus '' Ardea'' and coined the binomial name ''Ardea rufescens''. Gmelin based his description on that of the English ornithologist John Latham who in 1785 had included the species in his multi-volume ''A General Synopsis of Birds''. Latham had in turn based his own descriptio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intermediate Egret
The intermediate egret, median egret, smaller egret, or yellow-billed egret (''Ardea intermedia'') is a medium-sized heron. Some taxonomists put the species in the genus '' Egretta'' or ''Mesophoyx''. It is a resident breeder from east Africa across the Indian subcontinent to Southeast Asia and Australia. Taxonomy Some authorities classify the intermediate egret in its own monotypic genus, ''Mesophoyx'', while others place it with the smaller egrets in '' Egretta''. There are three recognised subspecies, and these are sometimes raised in to species: * ''A. i. brachyrhyncha'' Brehm, 1854 "yellow-billed egret" - sub-Saharan Africa * ''A.i. intermedia'' Wagler, 1827 "intermediate egret" - Asia from the Russian Far East to Japan to India and the Greater Sundas * ''A. i. plumifera'' Gould, 1848 "plumed egret" - eastern Indonesia, New Guinea and Australia. ''A.i. intermedia'' differs from ''A.i. brachyrhyncha'' and ''A. i. plumifera'' by having a black bill when in breeding pluma ...

Slaty Egret
The slaty egret (''Egretta vinaceigula'') is a small, dark egret. It is one of the species to which the ''Agreement on the Conservation of African-Eurasian Migratory Waterbirds'' (AEWA) applies. It is classified as Vulnerable, the biggest threat being habitat loss. Description Until 1971, the slaty egret and more widespread black egret ''Egretta ardesiaca'' were thought to be colour morphs of the same species but the slaty egret shows consistent features which separate it from the black egret. These are the yellow legs and the vinous brown throat of the slaty egret, which extends down right onto the belly in immature birds. The slaty egret does not display the characteristic "mantling" behaviour of the black egret. Distribution and population The slaty egret lives in south-central Africa. The largest populations are found in Zambia and Botswana. In Zambia there are maybe 500 to 1,000 individuals, mainly found at Liuwa Plain National Park, Kafue Flats and Lake Bangweulu i ...

Eastern Great Egret
The eastern great egret (''Ardea alba modesta''), a white heron in the genus '' Ardea'', is usually considered a subspecies of the great egret (''A. alba''). In New Zealand it is known as the white heron or by its Māori name ''kōtuku''. The subspecies was first described by British ornithologist John Edward Gray in 1831. Taxonomy This species was originally described as the "pure white heron of India", ''Ardea modesta,'' by Gray in 1831, but was later generally considered a synonym of ''Ardea alba'', by Ellman in 1861 through to the Peters checklist in 1979. It was elevated to species status again by Sibley and Monroe in 1990, and this was supported by a 2005 revision of the herons. It is still sometimes considered a subspecies of the great egret ''Ardea alba.'' Description Measuring in length and weighing , the eastern great egret is a large heron with all-white plumage. Its bill is black in the breeding season and yellow at other times, and its long legs are red or black. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egretta
''Egretta'' is a genus of medium-sized herons, mostly breeding in warmer climates. Representatives of this genus are found in most of the world, and the little egret, as well as being widespread throughout much of the Old World, has now started to colonise the Americas. These are typical egrets in shape, long-necked and long-legged. A few plumage features are shared, although several have plumes in breeding plumage; a number of species are either white in all plumages, have a white morph (e.g. reddish egret), or have a white juvenile plumage (little blue heron). The breeding habitat of ''Egretta'' herons is marshy wetlands in warm regions. They nest in colonies, often with other wading birds, usually on platforms of sticks in trees or shrubs. These herons feed on insects, fish, and amphibians, caught normally by cautious stalking. Taxonomy The genus ''Egretta'' was introduced in 1817 by the German naturalist Johann Reinhold Forster with the little egret as the type specie ...
