To the best of my knowledge this fine Swallow (of 

 which I first obtained a few individuals on the river 

 Okavango in 1859) never extends its migration so far 

 south as Damara Land proper; and, indeed, very few 

 individuals come much further south than the Okavango. 

 Those that came under my notice were always found in 

 large open forests, flying high above the tree tops in 

 pursuit of their insect prey, or occasionally perching 

 on lofty, isolated, and aged trees, and they were in 

 consequence by no means easy to procure.
