the Birds of Ngamiland. 373 



nest is more untidy than tliat of any other species of 

 Weaver-bird, and the ends of the grass are left sticking out 

 in all directions. It is an interesting fact that these birds 

 seem to inhabit their nests all the year round, roosting in 

 them during the winter, when the fiercest battles often take 

 place over disputed possession. I have occasionally heard 

 them singing delightfully in November.

Hyphantornis xanthops Ogilvie-Grant, Trans. Zool. Soc.

Iris cream-coloured ; bill black ; feet brown. 



A few examples of Jameson^s Weaver-bird were seen on 

 the densely-wooded islands in the Okavatigo marshes, but 

 they were rather uncommon. They seemed to keep almost 

 entirely to the larger trees, especially to those which had 

 festoons of creepers hanging from them. 



Hyphantornis collaris (Vieill.). 



Ploceus collaris Reich, iii. p. 61. 



a. ^ imm. Lake Ngami, 2700 ft., 3rd July. (No. 540, 

 G. L.) 



Iris hazel; bill black ; feet brown. 



This immature specimen of a Weaver-bird in freshly- 

 moulted plumage appears to be referable to H. collaris. It 

 agrees in most of the essential points, especially in the colour 

 of the bright canary-yellow wing-lining and under wing- 

 coverts ; the bill is somewhat shorter and smaller than in 

 any specimen in the British Museum Collection, but there 

 are no young birds of a similar age for comparison. The 

 primaries are rather distinctly edged with yellow, but are 

 in no way worn ; the sides and flanks are brownish-buff, a 

 character of immaturity.
