Egretta Garzetta Tree Greece
''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 ...

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 in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Reinhold Forster
Johann Reinhold Forster (22 October 1729 – 9 December 1798) was a German Continental Reformed church, Reformed (Calvinist) pastor and natural history, naturalist of partially Scottish descent who made contributions to the early ornithology of Europe and North America. He is best known as the naturalist on James Cook's Second voyage of James Cook, second Pacific voyage, where he was accompanied by his son Georg Forster. These expeditions promoted the career of Johann Reinhold Forster and the findings became the bedrock of colonial professionalism and helped set the stage for the future development of anthropology and ethnology. They also laid the framework for general concern about the impact that alteration of the physical environment for European economic expansion would have on exotic societies. Biography Forster's family originated in the Lord Forrester, Lords Forrester in Scotland from where his great-grandfather had emigrated after losing most of his property during the ...

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 ...

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' ...

Black Heron, Egretta Ardesiaca, At Marievale Nature Reserve, Gauteng, South Africa (30128438242)
Black is a color which results from the absence or complete absorption of visible light. It is an achromatic color, without hue, like white and grey. It is often used symbolically or figuratively to represent darkness. Black and white have often been used to describe opposites such as good and evil, the Dark Ages versus Age of Enlightenment, and night versus day. Since the Middle Ages, black has been the symbolic color of solemnity and authority, and for this reason it is still commonly worn by judges and magistrates. Black was one of the first colors used by artists in Neolithic cave paintings. It was used in ancient Egypt and Greece as the color of the underworld. In the Roman Empire, it became the color of mourning, and over the centuries it was frequently associated with death, evil, witches, and magic. In the 14th century, it was worn by royalty, clergy, judges, and government officials in much of Europe. It became the color worn by English romantic poets, businessmen an ...

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] |

White Faced Heron In Humpbybong Creek-08 (6114107932)
White is the lightest color and is achromatic (having no hue). It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore white togas as symbols of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the kings of France, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922). Greek and Roman temples were faced with white marble, and beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of new churche ...

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.

Pied Heron In Breeding Plumage - Fogg Dam - Middle Point - Northern Territory - Australia
A piebald or pied animal is one that has a pattern of unpigmented spots (white) on a pigmented background of hair, feathers or scales. Thus a piebald black and white dog is a black dog with white spots. The animal's skin under the white background is not pigmented. Location of the unpigmented spots is dependent on the migration of melanoblasts (primordial pigment cells) from the neural crest to paired bilateral locations in the skin of the early embryo. The resulting pattern appears symmetrical only if melanoblasts migrate to both locations of a pair and proliferate to the same degree in both locations. The appearance of symmetry can be obliterated if the proliferation of the melanocytes (pigment cells) within the developing spots is so great that the sizes of the spots increase to the point that some of the spots merge, leaving only small areas of the white background among the spots and at the tips of the extremities. Animals with this pattern may include birds, cats, cat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
