VI.— On ihe Birds of Bulawayo , Southern Rhodesia. By 
E. C. Chubb, Assistant Curator, Rhodesia Museum, 
Bulawayo. 
The material upon which this paper is based has mostly been 
collected by myself and others for the Rhodesia Museum 
during the last eighteen months, although it has been 
thought worth while, for the sake of completeness, to include 
in it a number of birds belonging to Mr. R. Douglas, which 
he has allowed me to examine. These are distinguished by 
an asterisk. 
Bulawayo is situated on the water-partiug which divides 
the Limpopo from the Zambesi River basin, at an altitude of 
1450 feet above the sea. The geological formation upon 
which it rests is schist, while there are outcrops of granite 
at several places within three or four miles of the town, e. g. 
at the Hillside Kopjes and at the Waterworks Reservoirs. 
Encircling the town for a radius of about three miles is 
the “ Commonage,” where most of the specimens have been 
collected, but a number of birds and nests have been obtained 
at Belle Vue Farm, where I am now living, some four miles 
south of Bulawayo. The Commonage consists of fairly 
thick Bush, composed largely of Acacia horrida and other 
leguminous trees, and several species of Combretum , while 
Copaifera mopani is common on the granite soil. These 
trees are all small, averaging in height from eight to ten 
feet ; the absence of large trees being due to the fact that 
fifteen years ago, prior to the occupation of the country by 
the White Man, the Commonage was under cultivation by 
the natives belonging to the chief Lobengula’s kraal, the 
site of the kraal being now occupied by the present town. 
The annual rainfall of Bulawayo ranges between 20 and
