About the Oriental Pratincole
The oriental pratincole (Glareola maldivarum), also known as the grasshopper-bird or swallow-plover, is a wader in the pratincole family, Glareolidae. The genus name is a diminutive of Latin glarea, "gravel", referring to a typical nesting habitat for pratincoles. The species name, maldivarum, refers to the type locality, the ocean near the Maldive Islands. The type specimen, caught alive at sea, survived for a month on flies.
The Oriental pratincole has short legs, long pointed wings and long forked tails. 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 chestnut.
Very good views are needed to distinguish the species from other pratincoles, particularly the very similar collared pratincole, which also has a chestnut underwing. The black-winged pratincole shares the black upperwing flight feathers, and lacks a white trailing edge to the wing. Those features are not always readily seen in the field, especially because the chestnut underwing appears black unless excellent views are obtained.
