The chestnut sparrow (Passer eminibey) is a species of passerine bird in the sparrow family Passeridae. It is the smallest member of the sparrow family, at about 11 cm (4.3 in) long. The breeding male has deep chestnut plumage and the female and juvenile are coloured a duller grey with some chestnut markings. Like its closest relatives in the genus Passer, the Arabian golden sparrow and the Sudan golden sparrow, it is gregarious and found in arid areas. Ranging through the east of Africa from Darfur in Sudan to Tanzania, it is found in dry savanna, papyrus swamps, and near human habitation. Adults and juveniles both feed mostly on grass seeds, and fly in flocks, often with other species of birds, to find food. It nests in trees, building its own domed nests, and also usurping the more elaborate nests of weavers.
Like the other members of the sparrow family, the chestnut sparrow is a small, chunky songbird with a thick bill suited to its diet of seeds. At 10.5 to 11.5 cm (4.1–4.5 in) in length, it is the smallest member of the sparrow family. It weighs between 12 grams (0.42 oz) and 17 grams (0.60 oz). Wing length ranges from 6.0 to 6.5 cm (2.4–2.6 in) in males and from 5.7 to 6.0 cm (2.2–2.4 in) in females. The tail, bill, and tarsus lengths are about 4 cm (1.6 in), 1 cm (0.39 in), and 1.5 cm (0.59 in) respectively.
The plumage of the breeding male is mostly a deep shade of chestnut in colour with black colouration on the face, wings, and tail. The breeding male is not easily confused with any other birds except the chestnut weaver, which is substantially larger and has white on its wings. The breeding male's legs and feet are horn (pale grey) in colour. The non-breeding male chestnut sparrow has white flecking on the upperparts, and much of its plumage is buff or whitish with chestnut crescent markings, until the bright chestnut of the breeding plumage is exposed by wear. The non-breeding male's bill fades to a dusky-tipped horn, similar to that of females, but without dusky tones on the cutting edge of the mandible (lower portion of beak).
