[About the end of September these Swifts arrived and 

 were very common, being found in flocks even during the 

 breeding-season. Numbers would fly in the evening in close 

 order to a great height, their whistling call being heard for 

 a long distance. The nests were built of mud and feathers, 

 and were placed, often two or three together, under the 

 krantzes on the kopjes.]

The sexes seem to be alike in plumage. The young birds

 are ochreous buff.
