Canastera Alianegra

Identificación

It is 24–28 cm (9.4–11.0 in) long, with short legs, long pointed wings and a forked tail. It has a short bill, which is an adaptation to aerial feeding. The back and head are brown, and the wings are brown with black flight feathers. The belly is white and the underwings are black. Very good views are needed to distinguish this species from other pratincoles, such as the collared pratincole and the oriental pratincole which may occur in its range. It is marginally larger than the collared pratincole, and is shorter-tailed and longer legged. Although the dark underwing and lack of a white trailing edge to the wing are diagnostic, these features are not always readily seen in the field, especially as the chestnut underwing of the collared pratincole appears black unless excellent views are obtained.
