New Guinea Flightless Rail Megacrex inepta

Justification
This enigmatic species is known from very few records over a wide range, and, although it is thought to be more abundant than data would indicate, it probably has a moderately small population, which is declining owing to hunting and habitat degradation. It consequently qualifies 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
Megacrex inepta is endemic to the lowlands of central New Guinea (Papua, formerly Irian Jaya, Indonesia and Papua New Guinea). There are very few records, but it is reported to be locally common, especially where sago is harvested (Gregory 1996, Taylor and van Perlo 1998). Its population size is unknown, but it appears to be small. There is no evidence of a significant decline.

Trend justification
There are no data on population trends; however, deforestation and trapping are suspected to be causing a slow decline.

Ecology
It inhabits lowland forest, especially wet thickets, swamp forest and mangroves.

Threats
Although flightless, it appears to be able to fight off attacks from dogs and to climb into trees to escape predators (Ripley 1964, Coates 1985). It is hunted in some areas, sometimes targeted specifically with sago lures, and it may be affected by feral pigs. Lowland forests across its range are under pressure from logging (K. D. Bishop in litt. 1994, P. Gregory in litt. 1994, Gregory 1996, Taylor and van Perlo 1998, T. Leary in litt. 2000).

Conservation Actions Underway
None is known. Conservation Actions Proposed
Conduct field surveys and interviews in villages to better understand its distribution, population density and threats. Use awareness programmes to discourage hunting. Effectively protect large areas of lowland rainforest.
