Range and habitat
It is found in Ethiopia, Kenya, Somalia, South Sudan, Tanzania, and Uganda. Its natural habitats are dry savanna and subtropical or tropical dry shrubland.
Description
It is a small tchagra, measuring 16–17 cm from bill tip to tail tip.[2] They are distinct from other tchagras in having a narrow, black median stripe over the crown,[3] without any superciliary stripe.[2] In addition the tertials and rectrices are mouse-brown in colour.
Habits
The male displays by fripping the wings in flight, followed by a series of down-slurred whistles.[3][2] They feed to a large extent on insects, but may in addition prey on chicks of other birds.[3]

There are two accepted races:[3]
- T. j. jamesi (Shelley, 1885) – Uganda, Ethiopia, Somalia, inland Kenya and very locally in South Sudan and Tanzania
