Obscure Berrypecker Melanocharis arfakiana

Justification
Little is known about this species, and there is considerable uncertainty over its true distribution, population size and trends. Its inconspicuous nature means that it has probably been widely overlooked, and it may well prove to be not threatened. However, until further information is available, it is not possible to evaluate its risk of extinction.

Distribution and population
Melanocharis arfakiana is known from two specimens and a series of more recent sight records from New Guinea (Papua, formerly Irian Jaya, Indonesia, and Papua New Guinea). The specimens were collected in 1867 in the Arfak Mts and in 1933 from 950 m near the upper Angabunga River (Coates 1990). The recent sightings have been from 640-1,100 m in the Tabubil area, where it is not uncommon, Boana on the Huon Peninsula, where it is common in degraded forest, Keki Lodge near Madang, and the Kokoda Trail near Port Moresby (Murray 1988, Coates 1990, Gregory 1993, Gregory 1995a, B. Whitney in litt. 2000, P. Gregory in litt. 2011, J. Hornbuckle in litt. 2011). Specimens from Tabubil and Boana differ slightly in plumage but are probably both of this species (P. Gregory in litt. 1999, B. Whitney in litt. 2000). It may be a genuinely extremely rare species, perhaps compressed into a narrow altitudinal belt between ecologically similar congeners (Coates 1990, P. Gregory in litt. 1994); however, although existing records suggest that the species is patchy and localised in occurrence, it could have been overlooked in many areas owing to its cryptic nature, and may in fact be widespread (del Hoyo et al. 2008, P. Gregory in litt. 2011).

Population justification
This is a poorly known species and no population estimates are available.

Trend justification
Given the paucity of sightings and uncertainty over its abundance, the population trend is not known. The species' apparent tolerance of degraded forest may indicate that the population trend is stable, but more information is required.

Ecology
It is a montane forest species, ranging from 640-1,100 m, and appears to be tolerant of secondary habitat. It feeds on berries and probably arthropods. It is thought to breed between May and October (del Hoyo et al. 2008).

Threats
Forests in these geographical and altitudinal ranges are under some threat from logging and clearance for agriculture. Habitat at Tabubil is being heavily degraded (P. Gregory in litt. 2011). Consequently, the species may be undergoing a slow decline (G. Dutson in litt. 2011). However, its tolerance of degraded forest and recent discovery in widely scattered sites suggest that it is not threatened (B. Whitney in litt. 2000).

Conservation Actions Underway
No targeted actions are known. The species has been recorded in Varirata National Park (P. Gregory in litt. 2011). Conservation Actions Proposed
Survey historical sites and potentially suitable habitat. Study its ecological requirements, tolerance of habitat degradation and threats.
