waterbirds recorded by this expedition as well. Out of the 21 species 011 the table not 

 less than 16 have a wide range över different parts of the continent. 3 species are widely 

 distributed över the East-South African Steppe region, one of them entering the Central 

 African Lake district. One (Halcyon semicosruleus semicceruleus) is a northeastern bird 

 but with closely related subspecies (which perhaps hardly are more than varieties) in 

 East Africa southwards to Lake Nyassa through the Central African Lake district, and 

 even in West Africa. The last Pomatorhynchus minutus is a chiefly western bird which 

 has pushed eastwards to the swamps of British East Africa.
