Geomalia Geomalia heinrichi

Justification
This species occupies a restricted range within which it is thought to be undergoing moderately rapid declines. As a result it is classified as Near Threatened.

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
Geomalia heinrichi is restricted to parts of Sulawesi, Indonesia. It is unrecorded in the east peninsula and south Sulawesi.

Population justification
The global population size has not been quantified, but the species is described as generally scarce, although apparently locally fairly common (del Hoyo et al. 2005).

Trend justification
This species is suspected to be declining at a moderately rapid rate, owing to inferred high rates of predation within its restricted range.

Ecology
It inhabits primary montane forest with dense undergrowth, moss forest and dwarf forest at 1,700-3,400 m. It is an agile and wary species, feeding (typically singly) on arthropods on the forest floor.

Threats
The number of feral domestic cats observed in Lore Lindu at night in 1999 suggest that declines may have resulted from this predation pressure. Forest loss is unlikely to have had serious impacts yet within its altitudinal range.

Conservation Actions Underway
No species-specific actions are known, although there are a number of protected areas on Sulawesi that may offer protection to its forest habitat. Conservation Actions Proposed
Research the impacts of introduced mammals on bird populations and productivity within its range. Use the results to guide appropriate action. If judged appropriate, implement control measures against cats.
