Calhandra-de-bico-curvo Alaemon alaudipes

A unique, large desert lark. On the ground, plumage is unimpressive with spotted breast and overall sandy tones, but in flight a magnificent white-and-black pattern is exposed. Males are slightly brighter-patterned than females. Bill is long and downcurved. Constantly runs on its long legs. Breeds on sandy and stony plains and low hills. Resident or nomadic. Song is a beautiful ascending series on flutey whistles followed by a descending trill; often given in a dramatic vertical display flight.
