The Collared Pratincole is a bird of open country, and is often seen near water in the evening, hawking for insects. It is found in the warmer parts of Europe, southwest Asia and Africa. Its 2–4 eggs are laid on the ground. It is migratory, wintering in tropical Africa, and is rare north of the breeding range.
It is 24–28 centimetres (9.4–11 in) long with a 60–70 centimetres (24–28 in) wingspan. It has short legs, long pointed wings, a long forked tail, and a short bill, which is an adaptation to aerial feeding. The back and head are brown, and the wings are brown with darker flight feathers. The belly is white. The underwings are chestnut, but look dark below.
Very good views are needed to distinguish this species from other pratincoles, such as the Black-winged Pratincole and the Oriental Pratincole, which may occur in its range. The latter species also has a chestnut underwing, but is shorter-tailed.
The Collared Pratincole is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
Briding in the Danube Delta in 2-3 places, very easy to see in spring time.
