Doria's Goshawk Megatriorchis doriae

Justification
This species occurs only in lowland forest which is subject in increasing pressure from logging. It is thought to be experiencing a moderately rapid population reduction and is consequently classified as Near Threatened.

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
Megatriorchis doriae is a little-known New Guinea endemic (Papua, formerly Irian Jaya, Indonesia and Papua New Guinea) (Beehler et al. 1986), including neighbouring Batanta island, Indonesia (Bishop 1986). It is rarely recorded, partly because of its unobtrusive habits, with for instance only one record in seven years of observation at Tabubil (P. Gregory in litt. 1999). Although it appears to be widespread and not immediately threatened (J. Diamond in litt. 1987, K. D. Bishop in litt. 1994), it may be suffering a moderately rapid population decline.

Population justification
The global population size has not been quantified, but the species is described as uncommon to rare, although more common in Ghana and not uncommon in Sierra Leone (Ferguson-Lees and Christie 2001).

Trend justification
There are no data on population trends; however, the population is suspected to be declining as a result of logging. The likely rate of decline remains unquantified.

Ecology
It is a forest species, sometimes also found in mangrove and semi-deciduous forest; mainly sea-level to 1,100 m, although sometimes to 1,400 m (Coates 1985, Beehler et al. 1986).

Threats
Its general tolerance of logging is poorly known but it has been seen repeatedly in logged forest near Port Moresby (P. Gregory in litt. 1999).

Conservation Actions Underway
CITES Appendix II. Conservation Actions Proposed
Survey to estimate population size and determine tolerance of logged forest. Set aside and protect important areas of lowland forest.
