collected in Uganda and British East Africa. 427 



sign of coming maturity is the change of colour in the bill 

 from black to coral-red. 



Much still remains to be found out regarding this bird's 

 nesting-habits. I do not think that they are strictly 

 polygamous. 



Localities. Katwe, Hima River, Kyetema, Sesse Islands, 

 Kulwe Isle, and Buziranjuvo, in Uganda.

A common bird. Plentiful in the towns and villages, and 

 open forests. In habits they are like the European Sparrow. 

 They build in holes in trees, in thatch of houses, and in 

 disused nests of other birds, such as Swallows'. The eggs 

 are like those of the P. domesticus, and vary in colour to the 

 same extent. 



Localities. Kyetema and Jinja, in Uganda. 



Passer griseus suahelicus. 



^ 2. 14. vii. 14. 



This is the British East African representative; in habits 

 it does not differ at all from the Uganda birds, neither are 

 its eggs different. 



Localities. Nairobi and Chania, British East Africa. 



Passer rufocinctus. 



(J 1-2. 26.V.12; 2.iv.l2. 



?. 27.xi.12. 



Common in certain localities, but by no means so plentiful 

 as P. g. Uganda or P. g. suahelicus. We have found them 

 breeding in June and October, in holes under the eaves of 

 an outhouse, in holes in trees, and in deserted Weavers' 

 nests. 



Localities. Naivasha, Nairobi, and Nakuru, in British East 



Africa.
