The mantle and back aredark grey with a tinge of glossy black, the fluffy rump is white and the uppertail coverts are black.

Distribution and habitat

It is found in western central and east Africa from Niger and Nigeria in the west east to Djibouti, Eritrea, Ethiopia and Somalia south to Uganda and Kenya.

Habits

The grey-headed batis is solitary or seen in pairs, spending time in the canopy of bushes, moving about restlessly, foraging in the shade in the middle of the bush. It feeds on insects.

The cup nest is made of bark strips and spider webs, concealed in the central fork of a thorn tree, in which 2–3 pale blue eggs are laid.
