Brown-headed jewel-babbler explained

The brown-headed jewel-babbler (Ptilorrhoa geislerorum), also known as the dimorphic jewel-babbler or brown-capped jewel-babbler, is a jewel-babbler in the family Cinclosomatidae. It is now usually considered to be distinct from the blue jewel-babbler, separated altitudinally and by varying behaviour, calls and female plumage.
