Dulit Frogmouth Batrachostomus harterti
BirdLife is updating this factsheet for the 2016 Red List
Please email us with any relevant information

This forest-dependent species is listed as Near Threatened because it is assumed to be experiencing a moderately rapid decline owing to the extensive loss of lowland forests from large areas of Borneo. It is not considered more threatened because it occurs in lower montane forest.

Taxonomic source(s)
del Hoyo, J.; Collar, N. J.; Christie, D. A.; Elliott, A.; Fishpool, L. D. C. 2014. HBW and BirdLife International Illustrated Checklist of the Birds of the World. Barcelona, Spain and Cambridge UK: Lynx Edicions and BirdLife International.

Distribution and population
Batrachostomus harterti is restricted to the Bornean Mountains Endemic Bird Area. Discounting its erroneous listing for Tanjung Puting National Park, it is known by only eight specimens from four areas in Sarawak, Malaysia, and one in West Kalimantan, Indonesia. The range and population have not been thoroughly investigated.

Population justification
The global population size has not been quantified, but the species is described as possibly not common, although little is known (Cleere 1998).

Trend justification
Although very poorly known, this species is probably declining at a moderately rapid rate, in line with forest clearance on Borneo. As it occurs at higher elevations it may have escaped more rapid declines.

The few available reliable records indicate that it favours hill and lower montane forest at 300-1,250 m (Orenstein et al. 2010).

There is steady habitat loss on Mt Dulit. Typically logging and agricultural expansion threaten forest habitats in Borneo.

Conservation Actions Underway
None are known. Conservation Actions Proposed
Before conservation priorities can be set, basic information on the species's ecology, status and likely threats are required. Protect areas of suitable habitat and safeguard against logging and agricultural encroachment.
