Biak Flycatcher Myiagra atra

Justification
This species is poorly known, and occurs within a very small range, suggesting that it has a small population. It is probably declining as a result of habitat loss, although it reportedly persists in secondary habitats, suggesting that it may not be imminently at risk, and consequently its habitat and population are not regarded as severely fragmented or restricted to a few locations. It is therefore considered Near Threatened, and should be carefully monitored.

Distribution and population
Myiagra atra is endemic to Biak-Supiori, Numfor and Rani in Geelvink Bay, Papua (formerly Irian Jaya), Indonesia (Mayr and Meyer de Schauensee 1939, Beehler et al. 1986). Observations from recent visits suggest that it may be fairly common on Biak (Gibbs 1993, N. Bostock in litt. 1993, Eastwood 1996a, B. Beehler and S. van Balen in litt. 2000, M. Van Beirs in litt. 2000).

Population justification
The global population size has not been quantified, but the species is described as fairly common to uncommon (del Hoyo et al. 2006).

Trend justification
There is little information on the status of this species. Although it is apparently tolerant of secondary forests, it is likely to have declined slowly as a result of habitat clearance on Biak.

Ecology
It is apparently largely confined to the interior hills, inhabiting primary, secondary and logged forest up to c.400 m, but is also occasionally recorded in mangroves (Mayr and Meyer de Schauensee 1939, Beehler et al. 1986, Gibbs 1993).

Threats
On Biak and Numfor, forest is under heavy threat from logging and subsistence farming, but there appears to be large areas of forest remaining in interior Supiori (Bishop 1982, K. D. Bishop in litt. 1996, D. Holmes in litt. 2000).

Conservation Actions Underway
No targeted conservation actions are known for this species.

Conservation Actions Proposed
Conduct repeated surveys within the species's range to determine current distribution and abundance, as well as assess population trends and rates of habitat loss. Conduct ecological studies to improve understanding of its precise habitat requirements, tolerance of secondary habitats and response to fragmentation. As a precaution, protect significant areas of suitable forest, in both strictly protected areas and community-led multiple use areas.
