Behaviour

The squacco heron is a migrant, wintering in Africa. It is rare north of its breeding range. The species has been recorded in Fernando de Noronha islands, and more rarely in mainland South America, as a vagrant. This is a stocky species with a short neck, short thick bill and buff-brown back. In summer, adults have long neck feathers. Its appearance is transformed in flight, when it looks very white due to the colour of the wings.

The squacco heron's breeding habitat is marshy wetlands in warm countries. The birds nest in small colonies, often with other wading birds, usually on platforms of sticks in trees or shrubs. Three to four eggs are laid. They feed on fish, frogs and insects.

Etymology

The English common name squacco comes via Francis Willughby (c. 1672) quoting a local Italian name sguacco. The current spelling comes from John Hill in 1752. [3]

The scientific name comes from Latin ardeola, a small heron (ardea), and ralloides, Latin rallus, a rail and Greek -oides, "resembling". [4]

Eurasian bittern Species of bird

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.

Glossy ibis Species of bird

The glossy ibis is a water bird in the order Pelecaniformes and the ibis and spoonbill family Threskiornithidae. The scientific name derives from Ancient Greek plegados and Latin, falcis, both meaning "sickle" and referring to the distinctive shape of the bill.

Purple heron Species of bird

The purple heron is a wide-ranging species of wading bird in the heron family, Ardeidae. The scientific name comes from Latin ardea "heron", and purpureus, "coloured purple". It breeds in Africa, central and southern Europe, and southern and eastern Asia. The Western Palearctic populations migrate between breeding and wintering habitats whereas the African and tropical-Asian populations are primarily sedentary, except for occasional dispersive movements.

Great egret Species of bird

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, with four subspecies found in Asia, Africa, the Americas, and southern Europe. Distributed across most of the tropical and warmer temperate regions of the world, it builds tree nests in colonies close to water.

Green heron Species of bird

The green heron is a small heron of North and Central America. Butorides is from Middle English butor "bittern" and Ancient Greek -oides, "resembling", and virescens is Latin for "greenish".

Black-crowned night heron Species of bird

Little egret Species of bird

The little egret is a species of small heron in the family Ardeidae. The genus name comes from the Provençal French Aigrette, "egret", a diminutive of Aigron, "heron". The species epithet garzetta is from the Italian name for this bird, garzetta or sgarzetta.

Marsh sandpiper Species of bird

The marsh sandpiper is a small wader. It is a rather small shank, and breeds in open grassy steppe and taiga wetlands from easternmost Europe to the Russian Far East. The genus name Tringa is the New Latin name given to the green sandpiper by Aldrovandus in 1599 based on Ancient Greek trungas, a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific stagnatilis is from Latin stagnum, "swamp".

Cattle egret Cosmopolitan species of heron

The cattle egret is a cosmopolitan species of heron found in the tropics, subtropics, and warm-temperate zones. It is the only member of the monotypic genus Bubulcus, although some authorities regard its two subspecies as full species, the western cattle egret and the eastern cattle egret. 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.

Caspian tern Species of bird

The Caspian tern is a species of tern, with a subcosmopolitan but scattered distribution. Despite its extensive range, it is monotypic of its genus, and has no accepted subspecies. The genus name is from Ancient Greek hudros, "water", and Latin progne, "swallow". The specific caspia is from Latin and, like the English name, refers to the Caspian Sea.

Little bittern Species of bird

The little bittern or common little bittern is a wading bird in the heron family, Ardeidae. Ixobrychus is from Ancient Greek ixias, a reed-like plant and brukhomai, to bellow, and minutus is Latin for "small".

Curlew sandpiper Species of bird

The curlew sandpiper is a small wader that breeds on the tundra of Arctic Siberia. The genus name is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-coloured waterside birds. The specific ferruginea is from Latin ferrugo, ferruginis, "iron rust" referring to its colour in breeding plumage.

Parasitic jaeger Species of bird

The parasitic jaeger, also known as the Arctic skua, Arctic jaeger or parasitic skua, is a seabird in the skua family Stercorariidae. The word "jaeger" is derived from the German word Jäger, meaning "hunter". The English "skua" comes from the Faroese name skúgvur[ˈskɪkvʊər] for the great skua, with the island of Skúvoy known for its colony of that bird. The general Faroese term for skuas is kjógvi[ˈtʃɛkvə]. The genus name Stercorarius is Latin and means "of dung"; the food disgorged by other birds when pursued by skuas was once thought to be excrement. The specific parasiticus is from Latin and means "parasitic".

Indian pond heron Species of heron

The Indian pond heron or paddybird is a small heron. It is of Old World origins, breeding in southern Iran and east to the Indian subcontinent, Burma, and Sri Lanka. They are widespread and common but can be easily missed when they stalk prey at the edge of small water-bodies or even when they roost close to human habitations. They are however distinctive when they take off with bright white wings flashing in contrast to the cryptic streaked olive and brown colours of the body. Their camouflage is so excellent that they can be approached closely before they take to flight, a behaviour which has resulted in folk names and beliefs that the birds are short-sighted or blind.

Chinese pond heron Species of bird

The Chinese pond heron is an East Asian freshwater bird of the heron family, (Ardeidae).

Night heron Common name for various birds

The night herons are medium-sized herons, 58–65 cm, in the genera Nycticorax, Nyctanassa, and Gorsachius. The genus name Nycticorax derives from the Greek for “night raven” and 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.

Pond heron Genus of birds

Pond herons (Ardeola) are herons, typically 40–50 cm (16–20 in) long with an 80–100 cm (30–40 in) wingspan. Most breed in the tropical Old World, but the migratory squacco heron occurs in southern Europe and the Middle East and winters in Africa. The scientific name comes from Latin ardeola, a small heron (ardea).

Malagasy pond heron Species of bird

The Malagasy pond heron is a species of heron of the family Ardeidae. They are primarily seen in the outer islands of the Seychelles, Madagascar, and on the east coast of Africa including Kenya, Tanzania, and Uganda. Being native to Madagascar, this species is often referred to as the Madagascar pond heron or Madagascar squacco heron. The population of this heron is estimated at 2,000–6,000 individuals, with only 1,300–4,000 being mature enough to mate.

Eastern cattle egret Species of bird

The eastern cattle egret is a species of heron found in the tropics, subtropics and warm temperate zones. Most taxonomic authorities lump this species and the western cattle egret together as subspecies of the cattle egret, but some separate them. 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.
