サケイ Syrrhaptes paradoxus

An unusual bird of dry plains and grasslands that looks like a cross between a dove and a grouse. Both sexes have a long, needle-thin tail, a rectangular black belly patch, and overall sandy-brown plumage. The male sports an orange-and-gray face and a pink tinge to his wings and back. The female is browner, with heavy speckling on the neck and nape. Flies in flocks, often gathering in groups of up to thousands strong at reliable waterholes.
