Herons
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 ...

Goliath Heron
The Goliath heron (''Ardea goliath''), also known as the giant heron, is a very large wading bird of the heron family, Ardeidae. It is found in sub-Saharan Africa, with smaller, declining numbers in Southwest and South Asia. Description This is the world's largest living heron (the extinct Bennu heron was larger). The height of the goliath heron is , the wingspan is and the weight is . The tarsus measures from and the wing chord averages around in length. The culmen measures from , while the bill from the gape measures around . In flight it has a slow and rather ponderous look and, unlike some other herons, its legs are not held horizontally. Male and female look similar, with an overall covering of slate gray and chestnut feathers. The head and its bushy crest, face, back and sides of the neck are chestnut. The chin, throat, foreneck and upper breast are white, with black streaks across the foreneck and upper breast. The lower breast and belly are buff with black streaks. ...

Boat-billed Heron
The boat-billed heron (''Cochlearius cochlearius''), colloquially known as the boatbill, is an atypical member of the heron family. It is the only member of the genus ''Cochlearius'' and was formerly placed in a monotypic family, the Cochleariidae. It lives in mangrove swamps from Mexico south to Peru and Brazil. It is a nocturnal bird, and breeds semi colonially in mangrove trees, laying two to four bluish-white eggs in a twig nest. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the boat-billed heron in his ''Ornithologie'' based on a specimen collected in French Guiana. He used the French name ''La Cuillière'' and the Latin ''Cochlearius''. The two stars (**) at the start of the section indicates that Brisson based his description on the examination of a specimen. Brisson placed the species in a new genus ''Cochlearius'' (with the same name as that of the species). When in 1766 the Swedish naturalist Carl Linnaeus updated his ''System ...

Ardea (bird)
''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] |

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 ...

Stork
Storks are large, long-legged, long-necked wading birds with long, stout bills. They belong to the family called Ciconiidae, and make up the order Ciconiiformes . Ciconiiformes previously included a number of other families, such as herons and ibises, but those families have been moved to other orders. Storks dwell in many regions and tend to live in drier habitats than the closely related herons, spoonbills and ibises; they also lack the powder down that those groups use to clean off fish slime. Bill-clattering is an important mode of communication at the nest. Many species are migratory. Most storks eat frogs, fish, insects, earthworms, small birds and small mammals. There are 19 living species of storks in six genera. Various terms are used to refer to groups of storks, two frequently used ones being a ''muster'' of storks and a ''phalanx'' of storks. Storks tend to use soaring, gliding flight, which conserves energy. Soaring requires thermal air currents. Ottomar Ans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egrets
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] |

Bittern
Bitterns are birds belonging to the subfamily Botaurinae of the heron family Ardeidae. Bitterns tend to be shorter-necked and more secretive than other members of the family. They were called ''hæferblæte'' in Old English; the word "bittern" came to English from Old French ''butor'', itself from Gallo-Roman ''butitaurus'', a compound of Latin ''būtiō'' (buzzard) and ''taurus'' (bull). Bitterns usually frequent reed beds and similar marshy areas and feed on amphibians, reptiles, insects, and fish. Bitterns, like herons, egrets, and pelicans, fly with their necks retracted, unlike the similar storks, ibises, and spoonbill Spoonbills are a genus, ''Platalea'', of large, long-legged wading birds. The spoonbills have a global distribution, being found on every continent except Antarctica. The genus name ''Platalea'' derives from Ancient Greek and means "broad", refe ...s, which fly with necks outstretched. Species There are currently 14 species divided into three genera ...

Ixobrychus
''Ixobrychus'' is a genus of bitterns, a group of wading bird in the heron family Ardeidae. It has a single representative species in each of North America, South America, Eurasia, and Australasia. The tropical species are largely resident, but the two northern species are partially migratory, with many birds moving south to warmer areas in winter. The species of the genus ''Ixobrychus'' are all small, with their four larger relatives being in the genus ''Botaurus''. They breed in large reedbeds, and can often be difficult to observe except for occasional flight views due to their secretive behaviour. Like other bitterns, they eat fish, frogs, and similar aquatic life. Taxonomy The genus ''Ixobrychus'' was introduced in 1828 by the Swedish naturalist Gustaf Johan Billberg who listed two members of the genus but did not specify the type species. This was designated as the little bittern by Witmer Stone in 1907. The genus name combines the Ancient Greek ''ixias'', a reed-like plan ...

Handbook Of The Birds Of The World
The ''Handbook of the Birds of the World'' (HBW) is a multi-volume series produced by the Spanish publishing house Lynx Edicions in partnership with BirdLife International. It is the first handbook to cover every known living species of bird. The series was edited by Josep del Hoyo, Andrew Elliott, Jordi Sargatal and David A. Christie. All 16 volumes have been published. For the first time an animal class will have all the species illustrated and treated in detail in a single work. This has not been done before for any other group in the animal kingdom. Material in each volume is grouped first by family, with an introductory article on each family; this is followed by individual species accounts (taxonomy, subspecies and distribution, descriptive notes, habitat, food and feeding, breeding, movements, status and conservation, bibliography). In addition, all volumes except the first and second contain an essay on a particular ornithological theme. More than 200 renowned speci ...

Spoonbill
Spoonbills are a genus, ''Platalea'', of large, long-legged wading birds. The spoonbills have a global distribution, being found on every continent except Antarctica. The genus name ''Platalea'' derives from Ancient Greek and means "broad", referring to the distinctive shape of the bill. Six species are recognised, which although usually placed in a single genus have sometimes been split into three genera. All spoonbills have large, flat, spatulate bills and feed by wading through shallow water, sweeping the partly opened bill from side to side. The moment any small aquatic creature touches the inside of the bill—an insect, crustacean, or tiny fish—it is snapped shut. Spoonbills generally prefer fresh water to salt but are found in both environments. They need to feed many hours each day. Taxonomy The genus ''Platalea'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. The genus name is Latin for ...
