The black-headed honeyeater (Melithreptus affinus), one of Tasmania's endemic species, is common in wet and dry sclerophyll forests. It can be distinguished from the strong-billed honeyeater, with which it often occurs in mixed flocks, by its completely black head.

The species feeds on insects within the canopy, often hanging upside down from branches.

The nest is constructed from fibrous bark, grasses and moss. Two to three spotted, pinkish eggs are laid.

The call is a high-pitched 'pssip'.
