Tigriornithinae is a subfamily of the heron family Ardeidae that contains the tiger herons. [1]
Egrets are herons, generally long-legged wading birds, that have white or buff plumage, developing fine plumes during the breeding season. Egrets are not a biologically distinct group from herons and have the same build.
The Pelecaniformes are an order of medium-sized and large waterbirds found worldwide. As traditionally—but erroneously—defined, they encompass all birds that have feet with all four toes webbed. Hence, they were formerly also known by such names as totipalmates or steganopodes. Most have a bare throat patch, and the nostrils have evolved into dysfunctional slits, forcing them to breathe through their mouths. They also have a pectinate nail on their longest toe. This is shaped like a comb and is used to brush out and separate their feathers. They feed on fish, squid, or similar marine life. Nesting is colonial, but individual birds are monogamous. The young are altricial, hatching from the egg helpless and naked in most. They lack a brood patch.
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 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 is also 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 hybridized in the area of contact.
The white-faced heron 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.
The tricolored heron, formerly known as the Louisiana heron, is a small species of heron native to coastal parts of the Americas. The species is more solitary than other species of heron in the Americas and eats a diet consisting mostly of small fish.
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.
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.
Egretta is a genus of medium-sized herons, mostly breeding in warmer climates.
The bare-throated tiger heron is a wading bird of the heron family, Ardeidae, found from Mexico to northwestern Colombia, with one recorded sighting from the United States in Hidalgo County, Texas. It is 80 cm (31 in) in length and weighs 1,200 g (42 oz).
The stripe-backed bittern is a bird species belonging to the family Ardeidae, which includes Herons, Egrets and Bitterns. 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 capped heron is a water bird endemic to the neotropics, inhabiting rainforest from the center of Panama to the south of Brazil. 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.
The white-crested tiger heron, also known as the white-crested bittern, is a species of heron in the family Ardeidae. It is in the monotypic genus Tigriornis. It is widely distributed across the African tropical rainforest.
The fasciated tiger heron is a species of heron in the family Ardeidae. It is present in southern Central America and parts of northern and central South America, where its natural habitat is rivers.
Tigrisoma is a genus of herons in the family Ardeidae.
The rufescent tiger heron is a species of heron in the family Ardeidae. It is found in wetlands from Central America through much of South America.
The zigzag heron is a species of heron in the family Ardeidae, also including egrets and bitterns. It is in the monotypic genus Zebrilus. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. Its natural habitat is subtropical or tropical swamps.
