Observation details
Br Wa hybrid ID based primarily on yellow crown, white throat and underparts with yellow wing bars. A pure F1 hybrid would show a black eye line. Black mask indicates probable further back-breeding/intergrade hybridization. Based on territorial defense - likely a male. Excluded a female GW Wa which should show dark gray throat and more olive on crown.
