23-8-2015 VILLALONGA RESERVOIR, VALENCIA - SQUACCO HERON (Ardeola ralloides)


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. It is of Old World origins, breeding in southern Europe and the Greater Middle East.

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.

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

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.


It is a bird that migrates from Europe to Africa during the winter, thriving in marshes, ponds, lakes, with reed beds and other vegetations. This bird pursues its prey quite sluggishly, crouching quietly at water edges. It is buffy brown at rest but becomes mostly white when in flight as its white wings and tail opens up for sight.

Squacco heron (Ardeola ralloides) is an elegant little hero with Old World origins, which breeds in the Greater Middle East and southern Europe. This bird feeds on small aquatic creatures, which it catches using its bill, after long minutes of waiting and hunching. It nests in thick reeds or dense willows, typically in a loosely-structured colony, with other heron cousins and even egrets.
