Yellow-eyed Starling Aplonis mystacea

Justification
This poorly known and probably nomadic species is thought to have a moderately small population, which is likely to be declining owing to hunting and habitat degradation. However, a better understanding of its status could result in this species being downlisted.

Taxonomic source(s)
Sibley, C. G.; Monroe, B. L. 1990. Distribution and taxonomy of birds of the world. Yale University Press, New Haven, USA.

Distribution and population
Aplonis mystacea has a scattered range across New Guinea (Papua, formerly Irian Jaya, Indonesia and Papua New Guinea) but is easily overlooked and may prove to be more widespread (Beehler et al. 1986, Coates 1990, Burrows 1993, Beehler and Bino 1995). It is a generally scarce and probably nomadic.

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

Trend justification
There are no data on population trends; however, the species is suspected to be declining slowly, owing to habitat loss and hunting.

Ecology
It is a species of lowland forest, usually in riverine or alluvial lowlands, but also occurs in the hills to 580 m (Beehler and Bino 1995).

Threats
This species may have a naturally small and scattered population threatened locally by logging and hunting. The one known breeding colony (of c.200 birds) was in a single large tree in a sparsely populated area, which was cut down in order to eat the eggs and chicks (Safford 1996).

Conservation Actions Underway
None is known. Conservation Actions Proposed
Regularly monitor the population at selected sites. Attempt to study movement patterns of individuals to better understand movements and habitat requirements. Protect significant areas of primary riverine and alluvial lowland forest, both at sites where it is known to occur, and more extensively within its known range. Research its tolerance of logged and degraded forest. Raise awareness of the scarcity of this species locally and find ways to prevent the felling of nesting trees.
