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 considered ...

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, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proardea
''Proardea'' is an extinct genus of heron, containing two species, ''Proardea amissa'' ("lost proto-heron") and ''Proardea? deschutteri'' from the Borgloon Formation of Belgium. It stood about 70 cm (2 ft 4 in) tall and was very similar to a modern heron in shape. The species is known from rather fragmentary fossils in the area of Quercy, France; dated remains are from Pech Desse, a Late Oligocene locality, but the original fossil, a single right tarsometatarsus (MNHN QU-15720), isn't precisely dated and may have come from deposits as early as Late Eocene in age. ''Proardea'' was apparently closely related to the true herons and egrets (Ardeinae). As these genera are only known from the Miocene onwards, ''Proardea'' possibly was a direct ancestor of today's herons and/or egrets. However, the Miocene genus ''Proardeola'' is closely related, or perhaps even synonymous, with ''Proardea''; the former's single species ''Proardeola walkeri'' may thus be ''Proardea walkeri ...

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] |
Pilherodius
The capped heron (''Pilherodius pileatus'') is a water bird endemic to the neotropics, inhabiting rainforest from the center of Panama to the south of Brazil.Ridgely, R. S., & Gwynne, J. A. (1989). ''A guide to the birds of Panama: with Costa Rica, Nicaragua, and Honduras''. Princeton University Press. It is the only species of the genus ''Pilherodius'', and one of the least known of the heron family, Ardeidae. It is superficially similar to the group of the night herons, but is active during daytime or at twilight.Payne, R. B., & Risley, C. J. (1976). ''Systematics and evolutionary relationships among the herons (Ardeidae)''. Museum of Zoology, University of Michigan. Taxonomy The capped heron was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1780 in his ''Histoire Naturelle des Oiseaux'' from a specimen collected in Cayenne, French Guiana. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the ''Planch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Quaternary Prehistoric Birds
Late Quaternary prehistoric birds are avian taxa that became extinct during the Late Quaternary – the Holocene or Late Pleistocene – and before recorded history, or more precisely, before they could be studied alive by ornithological science. They became extinct before the period of global scientific exploration that started in the late 15th century. In other words, this list basically deals with extinctions between 40,000 BC and 1500 AD. For the purposes of this article, a "bird" is any member of the clade Neornithes, that is, any descendant of the most recent common ancestor of all currently living birds. The birds are known from their remains, which are subfossil (not fossilized, or not completely fossilized). Some are also known from folk memory, as in the case of Haast's eagle in New Zealand. As the remains are not completely fossilized, they may yield organic material for molecular analyses to provide additional clues for resolving their taxonomic affil ...

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 species ...

Syrigma
The whistling heron (''Syrigma sibilatrix'') is a medium-sized, often terrestrial heron of South America. There are two subspecies, the southern ''S. s. sibilatrix'' and the northern ''S. s. fostersmithi''. Description The whistling heron measures 53 to 64 cm in length and weighs 521 to 546 g. The southern subspecies is bigger but has a shorter bill in proportion to the body. The overall impression of standing birds is gray, with flying birds showing conspicuous white rear parts (lower back, belly, and tail). In both subspecies, adults' upperparts except the lower back are blue-gray. The feathers of the sides of head, sides of the neck, breast, and scapular area are basically white but are stained gold to buff, perhaps by the powder down typical of herons or by secretions of the preen gland; the color varies from bird to bird. In the nominate subspecies, the crown and crest (separate plumes up to 4 cm long on the nape) are black and the upper wing coverts are cinna ...

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] |
Bubulcus
''Bubulcus'' is a genus of herons in the family Ardeidae. The genus ''Bubulcus'' was introduced in 1855 by the French naturalist Charles Lucien Bonaparte with the western cattle egret as the type species. The genus name is from Latin and means "cowherd". The genus contains two species: Some taxonomic authorities lump both species together, calling them cattle egrets, and making the genus monotypic.

Ardeola
Pond herons (''Ardeola'') are herons, typically long with an wingspan. Most breed in the tropical Old World, but the migratory squacco heron occurs in southern Europe and the Middle East and winters in Africa. The scientific name comes from Latin ''ardeola'', a small heron (''ardea''). These pond herons are stocky species with a short neck, short thick bill, typically buff or brownish back, and coloured or streaked fore neck and breast. In summer, adults may have long neck feathers. ''Ardeola'' herons are transformed in flight, looking very white due to the brilliant white wings. Their breeding habitat is marshy wetlands. They nest in small colonies, often with other wading birds, usually on platforms of sticks in trees or shrubs. Two to five eggs are laid. These herons feed on insects, fish Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butorides
''Butorides'' is a genus of small herons. It contains three similar species, the green heron or green-backed heron, ''Butorides virescens'', the lava heron (''Butorides sundevalli''), and the striated heron, ''Butorides striatus''. A fossil species, ''Butorides validipes'', is known from the Early Pleistocene of Florida in the United States. ''Butorides'' is from Middle English ''Butor'' "bittern" and Ancient Greek ''-oides'', "resembling". Adults of both extant species are about long, and have a blue-black back and wings, a black cap and short yellow legs. Juveniles are browner above and streaked below, and have greenish-yellow legs. The species have different underpart colours, chestnut with a white line down the front in green heron, and white or grey in striated. Both breed in small wetlands on a platform of sticks often in shrubs or trees, sometimes on the ground. The female lays three to five eggs. Both parents incubate for about 20 days until hatching, and feed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
