The American bittern is a species of wading bird in the heron family. It has a Nearctic distribution, breeding in Canada and the northern and central parts of the United States, and wintering in the U.S. Gulf Coast states, all of Florida into the Everglades, the Caribbean islands and parts of Central America.
The Eurasian bittern or great bittern is a wading bird in the bittern subfamily (Botaurinae) of the heron family Ardeidae. There are two subspecies, the northern race breeding in parts of Europe and across the Palearctic, as well as on the northern coast of Africa, while the southern race is endemic to parts of southern Africa. It is a secretive bird, seldom seen in the open as it prefers to skulk in reed beds and thick vegetation near water bodies. Its presence is apparent in the spring, when the booming call of the male during the breeding season can be heard. It feeds on fish, small mammals, fledgling birds, amphibians, crustaceans and insects.
Herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 74 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genus Botaurus 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 great egret (Ardea alba), also known as the common egret, large egret, or 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 has also been 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.
The black-crowned night heron [or black-capped night heron], commonly shortened to just night heron in Eurasia, is a medium-sized heron found throughout a large part of the world, including parts of Europe, Asia, and North and South America. In Australasia it is replaced by the closely related Nankeen night heron, with which it has hybridised in the area of contact.
The cinnamon bittern or chestnut bittern is a small Old World bittern, breeding in tropical and subtropical Asia from India east to China and Indonesia. It is mainly resident, but some northern birds migrate short distances. This species was formerly placed in the genus Ixobrychus.
The yellow bittern is a small bittern. It is of Old World origins, breeding in the northern Indian Subcontinent, east to the Russian Far East, Japan and Indonesia. It is mainly resident, but some northern birds migrate short distances. It has been recorded as a vagrant in Alaska and there is a single sighting in Great Britain, from Radipole Lake, Dorset on November 23, 1962 – however, the British Ornithologists' Union has always considered this occurrence to be of uncertain provenance and currently it is not accepted onto the official British List. This species was formerly placed in the genus Ixobrychus.
The black bittern is a bittern of Old World origin, breeding in tropical Asia from Pakistan, India, Bangladesh and Sri Lanka east to China, Indonesia, and Australia. It is mainly resident, but some northern birds migrate short distances. This species was formerly placed in the genus Ixobrychus.
Botaurus is a genus of bitterns, a group of wading birds in the heron family Ardeidae. The genus includes species that were previously placed in the genus Ixobrychus.
The least bittern is a small heron, the smallest member of the family Ardeidae found in the Americas. This species was formerly placed in the genus Ixobrychus.
Butorides is a genus of small herons. It contains three similar species, the striated heron Butorides striatus, the lava heron Butorides sundevalli, and the green heron Butorides virescens. They are closely related, and some authorities have considered them all to be subspecies of just one species; when treated so, the merged species is called green-backed heron. The name Butorides derives from Middle English Butor ("bittern") and the Ancient Greek suffix -oides, "resembling".
The terrestrial fauna of the Cocos (Keeling) Islands is unsurprisingly depauperate, because of the small land area of the islands, their lack of diverse habitats, and their isolation from large land-masses. However, the fauna dependent on marine resources is much richer.
Von Schrenck's bittern or Schrenck's bittern is a small bittern named after Leopold von Schrenck, the 19th-century Russian zoologist. It breeds in southeast Siberia, east China, the Korean Peninsula and Japan. It winters from the Malay Peninsula to the Greater Sunda Islands, Sulawesi and the Philippines. This species was formerly placed in the genus Ixobrychus.
The pinnated bittern, also known as the South American bittern, is a large member of the heron family (Ardeidae) found in the New World tropics. Like the other Botaurus bitterns, its plumage is mostly buffy-brown and cryptically patterned. Though it is a widespread species, it is rarely seen – presumably due to its skulking habits – and much about its life history remains little known.
The stripe-backed bittern is a South American bird species belonging to the family Ardeidae, which includes Herons, Egrets and Bitterns. It was formerly placed in the genus Ixobrychus. Commonly found near freshwater swamps, marshes, lake shores and streams, stripe-backed bitterns span over a wide distribution that divides into the northern and southern populations, spanning on both sides of the Andes. Although increasingly recognized and researched worldwide, much life history details are lacking concerning this species, which remains understudied compared to its similar looking sister clade, including the least bittern.
The New Zealand bittern is an extinct and enigmatic species of heron in the family Ardeidae. It was endemic to New Zealand and was last recorded alive in the 1890s.
The dwarf bittern is a species of heron in the family Ardeidae that is widely distributed across Sub-Saharan Africa avoiding only the very arid regions. This species was formerly placed in the genus Ixobrychus.
The black-backed bittern, also known as the black-backed least bittern or Australian little bittern, is a little-known species of heron in the family Ardeidae found in Australia and vagrant to southern New Guinea. Formerly lumped with the little bittern, it is one of the smallest herons in the world. This species was formerly placed in the genus Ixobrychus.
The eastern cattle egret is a species of heron found in the tropics, subtropics and warm temperate zones. Formerly, most taxonomic authorities lumped this species and the western cattle egret together, but the two cattle egrets are now treated as separate species. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea. It is native to southern and eastern Asia, and Australasia.
The western cattle egret is a species of heron found in the tropics, subtropics and warm temperate zones. Formerly, most taxonomic authorities lumped this species and the eastern cattle egret together, but the two cattle egrets are now treated as separate species. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea. Originally native to parts of Asia, Africa and Europe, it has undergone a rapid expansion in its distribution and successfully colonised much of the rest of the world in the last century.
