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.
