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 ...

Little Blue Heron
The little blue heron (''Egretta caerulea'') is a small heron of the genus '' Egretta''. It is a small, darkly colored heron with a two-toned bill. Juveniles are entirely white, bearing resemblance to the snowy egret. During the breeding season, adults develop different coloration on the head, legs, and feet. They have a range that encompasses much of the Americas, from the United States to northern South America. Some populations are migratory. Climate change will probably cause their distribution to spread north. They can be found in both saltwater and freshwater ecosystems. Their preference for either one depends on where they live. Nesting behaviors are documented by numerous sources. The adults build nests in trees, in colonies with other bird species. The number of eggs laid varies from place to place. The young mature quickly, requiring little attention from adults after about nineteen days of age. Both young and adults are sometimes preyed on by other species. Adults ...

White-faced Heron
The white-faced heron (''Egretta novaehollandiae'') also known as the white-fronted heron, and incorrectly as the grey heron, or blue crane, is a common bird throughout most of Australasia, including New Guinea, the islands of Torres Strait, Indonesia, New Zealand, and all but the driest areas of Australia. It is a medium-sized heron, pale, slightly bluish-grey, with yellow legs and white facial markings. It can be found almost anywhere near shallow water, fresh or salt, and although it is prompt to depart the scene on long, slow-beating wings if disturbed, it will boldly raid suburban fish ponds. Taxonomy The species was originally described by ornithologist John Latham in 1790. It was historically considered to be closely related to '' Ardea'' but for some time it was placed in its own genus—''Notophoyx''—because of the absence of the plumes typical in that genus. In his review of the family Ardeidae, American ornithologist Walter J. Bock placed the white-faced heron i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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''.

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] |
Black Heron
The black heron (''Egretta ardesiaca''), also known as the black egret, is an African heron. It is well known for its habit of using its wings to form a canopy when fishing. Description The black heron is a medium-sized (42.5–66 cm in height), black-plumaged heron with black bill, lores, legs and yellow feet. In breeding plumage it grows long plumes on the crown and nape. Distribution and habitat The black heron occurs patchily through Sub-Saharan Africa, from Senegal and Sudan to South Africa, but is found mainly on the eastern half of the continent and in Madagascar. It has also been observed in Greece and Italy. It prefers shallow open waters, such as the edges of freshwater lakes and ponds. It may also be found in marshes, river edges, rice fields, and seasonally flooded grasslands. In coastal areas, it may be found feeding along tidal rivers and creeks, in alkaline lakes, and tidal flats. Habits The black heron uses a hunting method called ''canopy feeding ...

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 ...

Pied Heron
The pied heron (''Egretta picata''), also known as the pied egret is a bird found in coastal and subcoastal areas of monsoonal northern Australia as well as some parts of Wallacea and New Guinea. Taxonomy The species was originally described by ornithologist John Gould in 1845. Recent taxonomists put this species in the genus ''Egretta''. There are no recognised subspecies. Description It is a small heron, 43–55 cm long, with dark slaty wings, body, and crested head, with a white throat and neck. The appearance is similar to the white-necked heron. Males (247–280 g) are heavier than females (225–242 g), but the two are similar in appearance. Immature birds lack the crest as well as the dark colouring on the head and may look like small versions of the white-necked heron. The juveniles were once classified as a separate species. Distribution and habitat Its habitat mainly comprises a range of wetlands and wet grasslands. Behaviour Call The call of the ...

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 p ...

Heron
The herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 72 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genera ''Botaurus'' and ''Ixobrychus'' are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus ''Zebrilus'', form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks. The classification of the individual heron/egret species is fraught with difficulty, and no clear consensus exists about the correct placement of many species into either of the two major genera, '' Ardea'' and '' Egretta''. Similarly, the relationships of the genera in the family are not completely resolved. However, one species formerly consid ...

Ardea (genus)
''Ardea'' is a genus of herons. The genus name comes from Latin ''ardea'' "heron". These herons are generally large in size, typically 80–100 cm or more in length. These large herons are associated with wetlands where they prey on fish, frogs, and other aquatic species. Most members of this almost worldwide group breed colonially in trees, building large stick nests. Northern species such as great blue, grey, and purple herons may migrate south in winter, although the first two do so only from areas where the waters freeze. These are powerful birds with large spear-like bills, long necks and long legs, which hunt by waiting motionless or stalking their prey in shallow water before seizing it with a sudden lunge. They have a slow steady flight, with the neck retracted as is characteristic of herons and bitterns; this distinguishes them from storks, cranes, flamingos, and spoonbills, which extend their necks. Taxonomy The genus ''Ardea'' was introduced in 1758 by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
