Hairy-breasted Barbet

Tricholaema hirsuta

Un grande barbetto scuro delle foreste umide di bassa e media quota. Il dorso è nero con macchie gialle e le parti inferiori sono gialle con striature e macchie nere. Il disegno della testa varia geograficamente. La gola può essere striata o di un nero uniforme, e il viso può essere picchiettato (Africa centrale) o nero con un sopracciglio bianco e un baffo (parti settentrionali e occidentali dell'areale). Simile in qualche modo al Barbetto macchiettato, ma più grande in generale, con un becco più robusto e una calotta scura. Solitamente rilevato dalla voce: una serie lunga e lenta di richiami bassi e cavi. Occasionalmente emette anche una serie di fischi molto più rapida.
