This very handsome species is common in Damara 

 and Great Namaqua Land during the rainy season, and 

 is found at all seasons at Lake Ngami and on the river 

 Okavango. 



It is usually found in flocks, and may not unfrequently 

 be seen perching on dry trees near the water ; its flesh 

 is very good. 



The comb on the bill is found in the male bird only ; 

 this is black, and the bill is nearly so ; the tarsi and toes 

 are lead-coloured ; the irides dark brown.

[I believe that all the figures of this species which have been 

 published have been taken from Indian specimens ; but I agree 

 with Drs. Finsch and Hartlaub (loc. cit.} in considering these to 

 be specifically identical with African examples. ED.]
