 Cuculus gularis, Sharpe's Cat. No. 104. 



This Cuckoo is pretty common in the rainy season 

 throughout Damara Land and in some parts of Great 

 Namaqua Land. Its flight is very rapid and zig-zag ; 

 but it does not move far at a time, usually taking refuge, 

 after being disturbed, in the nearest convenient tree. 



The iris is yellowish brown ; the tips of the mandibles 

 dark brown, their base yellowish, shading into greenish 

 yellow in the intermediate parts. 



[The yellow or " yellowish " base of the upper mandible in 

 this species, above referred to by Mr. Andersson, is perhaps the 

 readiest criterion by which it may be distinguished from Cuculus 

 canorus, in which the whole upper mandible is of a black horn- 

 colour, except a very narrow yellow margin below each nostril. 



Mr. R. B. Sharpe possesses a specimen of Cuculus gularis, 

 obtained by Mr. Andersson at Objimbinque, and another pro- 

 cured by him in Ondonga. ED.]

This beautiful species is by no means uncommon in 

 Little Namaqua Land ; but to the north of the Orange 

 Kiver I have only met with it in the neighbourhood of 

 the river Okavango, where it is both scarce and shy,
