This specimen, rather a brightly-coloured bird, closely 
resembles a male example from Natal in the British 
Museum, but all the black markings, especially those on the 
head and back, are more pronounced, more so than in any 
other specimen of C. natalensis that I have examined. The 
occurrence of the Natal Nightjar on the Baro River extends 
its known range a long way to the north. Doggett procured 
a specimen at Burumba, South Uganda, and there are three 
examples in the Jackson Collection procured near Entebbe.

Four of the males of the Standard-winged Nightjar have 
their ninth primary quill fully developed; two others are 
young in female-like plumage, but with the plumage of the 
back blacker and the wing somewhat longer than in the 
female.

The above-mentioned specimens vary much in the ground-

others sandy brown. All but one of the birds from the
