The squacco heron (Ardeola ralloides) is a small heron, 44–47 cm (17+1⁄2–18+1⁄2 in) long, of which the body is 20–23 cm (8–9 in), with 80–92 cm (31+1⁄2–36 in) wingspan. [2] It is of Old World origins, breeding in southern Europe and the Greater Middle East.
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. The squacco heron is a host of the Acanthocephalan intestinal parasite Ardeirhynchus spiralis . [3]
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. [4]
The scientific name comes from Latin ardeola, a small heron (ardea), and ralloides, Latin rallus, a rail and Greek -oides, "resembling". [5]
The Squacco Heron uses freshwater localities throughout Europe and the Middle East as breeding grounds to later migrate south to the Sub-Saharan African region. Non-breeding Squacco Herons share similar traits with other heron species like the Indian Pond Heron and Malagasy Pond Heron which show tawny color plumage, lighter streaking, smaller bill, and narrower wing tips.

The grey heron is a long-legged wading bird of the heron family, Ardeidae, native throughout temperate Europe and Asia, and also parts of Africa. It is resident in much of its range, but some populations from the more northern parts migrate southwards in autumn. A bird of wetland areas, it can be seen around lakes, rivers, ponds, marshes and on the sea coast. It feeds mostly on aquatic creatures which it catches after standing stationary beside or in the water, or stalking its prey through the shallows.
The purple heron is a wide-ranging heron species. It breeds in Africa, central and southern Europe, and southern and eastern Palearctic. 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. It is similar in appearance to the more common grey heron but is slightly smaller, more slender and has darker plumage. It is also a more evasive bird, favouring densely vegetated habitats near water, particularly reed beds. It hunts for a range of prey including fish, rodents, frogs and insects, either stalking them or standing waiting in ambush.
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 ring-necked duck is a diving duck from North America commonly found in freshwater ponds and lakes. The scientific name is derived from Greek aithuia, an unidentified seabird mentioned by authors including Hesychius and Aristotle, and Latin collaris, "of the neck" from collum, "neck".
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".
The little egret is a species of small heron in the family Ardeidae. It is a white bird with a slender black beak, long black legs and, in the western race, yellow feet. As an aquatic bird, it feeds in shallow water and on land, consuming a variety of small creatures. It breeds colonially, often with other species of water birds, making a platform nest of sticks in a tree, bush or reed bed. A clutch of three to five bluish-green eggs is laid and incubated by both parents for about three weeks. The young fledge at about six weeks of age.
The solitary sandpiper is a small shorebird. The genus name Tringa is the Neo-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 solitaria is Latin for "solitary" from solus, "alone".
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 Neo-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".
The striated heron also known as mangrove heron, little green heron or green-backed heron, is a small heron, about 44 cm tall. Striated herons are mostly sedentary and noted for some interesting behavioural traits. Their breeding habitat is small wetlands in the Old World tropics from west Africa to Japan and Australia, and in South America and the Caribbean. Vagrants have been recorded on Oceanic islands, such as Chuuk and Yap in the Federated States of Micronesia, the Marianas and Palau; the bird recorded on Yap on February 25, 1991, was from a continental Asian rather than from a Melanesian population, while the origin of the bird seen on Palau on May 3, 2005 was not clear.
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.
The red-necked stint is a small migratory wader. The genus name is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-coloured waterside birds. The specific ruficollis is from Latin rufus, "red" and collum, "neck".
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.
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 white-headed duck is a small diving duck some 45 cm (18 in) long. The male has a white head with black crown, a blue bill, and reddish-grey plumage. The female has a dark bill and rather duller colouring. Its breeding habitat is lakes with open water and dense vegetation at the margin. It dives under water and feeds on aquatic vegetation as well as some animal matter. It is more likely to swim away from a perceived threat than to fly. This duck is known from Spain, North Africa, Western Asia and Central Asia. Populations are declining, mostly due to loss of habitat and pollution, and the International Union for Conservation of Nature has rated the bird's status as "endangered".
The Chinese pond heron is an East Asian freshwater bird of the heron family, (Ardeidae). It is one of six species of birds known as "pond herons". It is parapatric with the Indian pond heron to the west and the Javan pond heron to the south, and these three are presumed to form a superspecies. As a group they are variously affiliated with the squacco heron or the Malagasy pond heron. As of mid-2011 there are no published molecular analyses of pond heron interrelationships and osteological data is likewise not analyzed for all relevant comparison taxa.
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 Javan pond heron is a wading bird of the heron family, found in shallow fresh and salt-water wetlands in Southeast Asia. Its diet comprises insects, fish, and crabs.
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).
The Malagasy pond heron, also known as the Madagascar pond heron or Madagascar squacco heron, is a species of heron of the family Ardeidae. They breed in Madagascar, Réunion and the Seychelles, and spend the non-breeding season in eastern mainland Africa. The population is estimated to number only 1,300–4,000 adults and the species is considered endangered.
The rufous-bellied heron is a species of heron in the genus Ardeola, the pond herons, of the family Ardeidae. It is found in southern Africa.
