Description

The grey-headed silverbill is a stocky bird with a grey head studded with white dots. Its body is greyish-brown with partly black wings and tail and a white rump. The juvenile can be told by its white rump. Adult male is approximately 11.5 cm in length with wing length 6.5 cm.

Habitat

The grey-headed silverbill is commonly found in dry savanna habitat but never too far away from water. It wanders widely, influenced by weather and shifting availability of sources of water.

Behavior and ecology

The grey-headed silverbill is gregarious, moving in small flocks and often mixing with African silverbill.

Food and feeding

The grey-headed silverbill feeds mostly on grass seeds. But it has been suggested that the species also feed on insects which are more a source of moisture than dry seeds.
