Gorsachius
''Gorsachius'' is a genus of Old World night herons typically found near water in forested regions. These are medium-sized herons which are migratory in the colder parts of their ranges, but otherwise resident. They are the least known, most strictly nocturnal, smallest and overall rarest night herons. Three of the four species are found in East, South and South-east Asia, while the last species, the white-backed night heron, is found in sub-Saharan Africa. The Japanese and Malayan night herons resemble each other, being relatively short-billed and overall brown with a dark line from the throat to the upper belly. The larger white-eared and white-backed night herons are darker, with distinctive white markings on the face and neck in the former, and an entirely black head in the latter. Their behavior, especially that of the white-eared night heron, is relatively poorly known compared to that of other night herons, but they nest alone or in small groups, and a clutch of two to f ...

Japanese Night Heron
The Japanese night heron (''Gorsachius goisagi'') is a species of night heron found in East Asia. It breeds in Japan, and winters in the Philippines and Indonesia. It is also seen in the spring and summer in Korea and the Russian Far East. The Japanese night heron prefers dense, damp forest, in both its breeding and winter ranges. Common until the 1970s, this species is threatened by deforestation in its summer and winter ranges for timber and farmland. Other documented threats include the introduction of the Siberian weasel (''Mustela sibirica'') in its breeding range and nest predation by crows, due to the increasing crow populations. The current population is estimated at less than 1,000 mature individuals. Accordingly, the Japanese night heron is marked as a protected species in Japan and Hong Kong. Future actions proposed to conserve this species include surveying its breeding habits throughout Japan and the Philippines, protecting its habitat, creating more public interest ...

White-eared Night Heron
The white-eared night heron (''Gorsachius magnificus'') is a species of heron in the family Ardeidae. It is found in southern China and northern Vietnam. IN 2018, it has been also reported from Valmiki National Park, India. It is threatened by habitat loss and habitat fragmentation. Taxonomy The white-eared night heron was collected in Hainan by John Whitehead. It was described as ''Nycticorax magnifica'' by William Robert Ogilvie-Grant in 1899. The species is monotypic. Distribution and habitat This heron is found in southern China and northern Vietnam. Its range size is estimated at . By 2001, the species had only been recorded from about 20 localities; in the ten years from 2001 to 2011, surveys discovered it in more than 30 localities, making its known range much larger. Its natural habitat is subtropical or tropical forests and rivers. It has also been found in human-modified habitats. Description The length is . The male is mostly blackish-brown. The neck-sides are chestn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

White-backed Night Heron (Gorsachius Leuconotus) (6001840951)
The white-backed night heron (''Gorsachius leuconotus'') is a species of medium-sized heron in the family Ardeidae, found in sub-Saharan Africa. Taxonomy The German naturalist Johann Wagler described the white-backed night heron as ''Ardea leuconotus'' in 1827. Today the IOC World Bird List places it in the genus ''Gorsachius'', while BirdLife International and the ''Handbook of the Birds of the World'' place it in ''Calherodius''. Its name derives from a patch of white feathers that form a triangle on its back. Description The white-backed night heron is in length with a black head and a short crest, or prominent feather display on the top of its head. The heron has large red eyes with white-ringed markings around them, and the lores, or the region behind the eye, are a pale yellow hue. The throat feathers are white, whereas the neck and breast are rufous, or a reddish-brown hue. There is a notable white triangular patch along the back formed by the white scapulars, or small ...

Nycticorax
''Nycticorax'' is a genus of night herons. The name ''Nycticorax'' means "night raven" and derives from the Ancient Greek νύκτος, ''nuktos'' "night" and κοραξ, ''korax'', "raven". It refers to the largely nocturnal feeding habits of this group of birds, and the croaking crow-like call of the best known species, the black-crowned night heron. These are medium-sized herons which often are migratory in the colder parts of their ranges. Adults are short-necked, relatively short-legged and stout herons; the two extant species both have a black crown and a whitish belly, while the wings, chest, neck and auriculars are grey or rufous depending on the species. Young birds are brown, flecked with white and grey, and are quite similar to each other in the extant species. At least some of the extinct Mascarenes taxa appear to have retained this juvenile plumage in adult birds. Night herons nest in colonies on platforms of sticks in a group of trees, or on the ground in pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Sub-Saharan Africa
Sub-Saharan Africa is, geographically, the area and regions of the continent of Africa that lies south of the Sahara. These include West Africa, East Africa, Central Africa, and Southern Africa. Geopolitically, in addition to the List of sovereign states and dependent territories in Africa, African countries and territories that are situated fully in that specified region, the term may also include polities that only have part of their territory located in that region, per the definition of the United Nations (UN). This is considered a non-standardized geographical region with the number of countries included varying from 46 to 48 depending on the organization describing the region (e.g. UN, WHO, World Bank, etc.). The Regions of the African Union, African Union uses a different regional breakdown, recognizing all 55 member states on the continent - grouping them into 5 distinct and standard regions. The term serves as a grouping counterpart to North Africa, which is instead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
