Swahili Sparrow Passer suahelicus NOMENCLATURE Passer griseus suahelicus Reichenow, Vog. Afr. 1904 3: 231. Bussissi, [Mwanza district, northern Tanzania]. Passer suahelicus (Reichenow) 1904. Subspecies: none. Synonyms: none.

In the arid area that it occupies, it has to wander extensively to find food, settling down to breed only when conditions become suitable. This normally follows the start of the seasonal rains (Fig. 16) and, as this can vary from year to year, the bird is an opportunistic breeder both in time and in space. For example, in 1984 no breeding occurred in northern Senegal where the rains failed and there was a complete absence of ground cover beneath the thorn trees. Whereas in central Senegal, where some rain had fallen, there was a flush of green vegetation beneath the thorn trees and the birds formed breeding colonies in the trees.
