タンビモリチメドリ Turdoides atripennis

A chunky, short-tailed babbler with a purple-brown body, a yellowish bill and legs, and a mostly silver-gray head; the amount of black and gray on the throat and crown differ geographically. Unmistakable if seen well. Family groups of 5–12 are local residents skulking in the undergrowth and tangles of forest, secondary growth, and riparian thickets in savanna. Groups mostly communicate with dry harsh grating calls and chattering, but occasionally give a whimsical high-pitched, downslurred thrush-like whistle: “wheeeer.”
