|Ptilorrhoa caerulescens geislerorum
(A.B. Meyer, 1892)
The brown-headed jewel-babbler (Ptilorrhoa caerulescens geislerorum), also known as the dimorphic jewel-babbler or brown-capped jewel-babbler, is a jewel-babbler in the family Psophodidae. It is usually considered to be conspecific with the blue jewel-babbler, but is sometimes considered a distinct species separated altitudinally and by varying behaviour, calls and female plumage.
