I can ouly find a single note of having come across the 

 Sociable Lapwing. I killed one of a pair which were feeding 

 together on some newly-ploughed land at Khartoum in 

 February 1903. It was in immature plumage, with buff 

 superciliary circlet, grey arrow-head markings on the breast, 

 and some chesnut feathers on the lower surface.

The little Caspian Plover is abundant at Khartoum and 

 on the White Nile during the winter, frequenting cultivated 

 land or sandy desert near the river. Flocks generally feed in 

 very open company, but unite at once when disturbed, and 

 are then wild and difficult to approach again. They are fond 

 of searching for insect-food among garbage and carrion.
