 the Zambesi VaUey. I shot a few of what I am nearly sure were 

 of this species on the Athi Plains in British East Africa.

 but it appears much to resemble the other Sandgrouse in its 

 habits, being generally found in flocks which split up during 

 the breeding-season. Its flight is swift, and its note a curious 

 shrill whistle.

 are coated with dry grass. They are fond of basking in the
