The Black-headed Honeyeater (Melithreptus affinis) is a species of bird in the Meliphagidae family. It is one of two members of the genus Melithreptus endemic to Tasmania. Its natural habitats are temperate forests and Mediterranean-type shrubby vegetation.

Taxonomy

The Black-headed Honeyeater was described in 1839 as Eidopsarus affinis. John Gould described it as Melithreptus melanocephalus in 1844, likely unaware of its earlier name.[1]

Molecular studies show the Black-headed Honeyeater is most closely related to the White-naped Honeyeater, and that their next closest relative is the Western White-naped Honeyeater. All are members of the genus Melithreptus with several species, of similar size and (apart from the Brown-headed Honeyeater) black-headed appearance, in the honeyeater family Meliphagidae. The next closest relative outside the genus is the much larger but similarly marked Blue-faced Honeyeater.[2] More recently, DNA analysis has shown honeyeaters to be related to the Pardalotidae (pardalotes), Acanthizidae (Australian warblers, scrubwrens, thornbills, etc.), and the Maluridae (Australian fairy-wrens) in a large Meliphagoidea superfamily.[3]

Description

A mid-sized honeyeater, it is olive green above and white below, with a wholly black head that lacks the white nape of its relatives. It has a blue-white patch of bare skin around the eye. Its beak is small.

Distribution and habitat

The Black-headed Honeyeater is endemic to Tasmania, where it is found in wet and dry sclerophyll forests, as well as scub and heathland, and subalpine habitats to an altitude of 1200 m (4000 ft).

Feeding

Insects form the bulk of the diet, and the Black-headed Honeyeater specialises in foraging among the foliage of trees, as opposed to probing the trunk for prey which is practised by its relative the Strong-billed Honeyeater, and the two species rarely overlap.[4] Birds often hang upside down from branches while foraging.
