Mr. S. A. Neave on the Birds of 
Bill olive-brownish, lower mandible yellowish; feet dusky; 
iris orange-yellow ; orbit yellowish. 
A very abundant bird on the shores of L. Bangweolo and 
the river-banks in the neighbourhood. It is usually very 
tame, and immense numbers are often to be seen crowded 
together on the bushes by the water-side. Native name 
“ Nondo. - ”

I only saw this remarkable bird on one occasion, and that 
was on a large open plain in the Kalungwisi district, in 
September 1908.

No serious attempts were made to collect Vultures. 
They seem, strange to say, to be entirely absent from a large 
part of the High Plateau country. This species seems to be 
the commonest, occurring in the Luangwa Valley in fair 
numbers.
