Henna-tailed Jungle-flycatcher Rhinomyias colonus
BirdLife is updating this factsheet for the 2016 Red List
Please email us with any relevant information

This species is listed as Near Threatened because its population is assumed to have declined moderately rapidly within its moderately small range.

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
Rhinomyias colonus is restricted (if one excludes dubious records from East Sulawesi attributed to the race "subsolanus") to Banggai (where subspecies pelingensis occurs on Peleng) and the Sula Islands (where the nominate subspecies colonus occurs on Taliabu, Seho, Mangole and Sanana), Indonesia. As well as having a restricted range, it has probably declined owing to extensive clearance of lowland forest, and is apparently generally uncommon throughout its range.

Population justification
The population size is unknown, but the species is described as uncommon or locally common (del Hoyo et al. 2006).

Trend justification
This species has almost certainly experienced a decline because it shows an association with forest, occurring at the highest densities in undisturbed forest, and forest clearance within its range has been extensive. Any decline is estimated to be moderately rapid.

It inhabits lowland forest up to 300 m. Although it has been found in degraded forest, its preferred habitat appears to be undisturbed forest.

Ongoing forest loss and degradation through logging and agricultural encroachment, combined with its restriction to the lowlands, is a cause for some concern.

Conservation Actions Underway
None are known. Conservation Actions Proposed
Protect areas of lowland forest within the species's range. Enforce restrictions on agricultural encroachment and logging within such protected areas. Generate density estimates to inform a revised population estimate for the species. Estimate population trends by calculating rates of forest loss within its range using satellite imagery and remote sensing techniques.
