Venezuelan Wood-quail Odontophorus columbianus is listed as Near Threatened under criterion B1a+b(i,ii,iii,iv) because, although it has an Extent of Occurrence estimated at 9,400 km2, within which it is suspected to be declining owing to habitat loss and hunting pressure, the population is not considered to be severely fragmented or restricted to a few locations. Up-to-date information is requested on this species’s population, the likely rate of decline over 12 years (estimate of three generations) and the severity of threats.

Further information on this species is requested, including details of its likely sub-population structure (the number of sub-populations and the size of the largest and/or the maximum percentage of all mature individuals in one sub-population) and the level of habitat fragmentation in its range (that is, the percentage of suitable habitat that exists in patches too small to support viable populations).

Edwards’s Pheasant, Lophura edwardsi, is endemic to the lowland forests of central Vietnam and is currently listed as Endangered; comments are sought on the species, in particular whether its total population size is likely to now number fewer than 250 mature individuals, in order to determine whether it may warrant uplisting to Critically Endangered. Continue reading
Despite on-going uncertainty about the size and trend of some national populations, a balanced assessment of the available evidence suggests that overall the population of this species is probably declining at a rate approaching 30% over 12 years (three generations). For this reason, it is proposed that the species be uplisted to Near Threatened. Comments on this proposal are welcome, as are any quantitative data that could further inform the assessment.

Archived 2011-2012 topics: White-necklaced Partridge (Arborophila gingica): downlist to Near Threatened?
Apparently there has been no over-arching study of population densities and total population size for this species, but further information is required to help assess whether the species actually numbers more than 10,000 mature individuals and therefore approaches the thresholds for Vulnerable under criterion C2a(i) and should be downlisted to Near Threatened.

Archived 2011-2012 topics: Grey-striped Francolin (Francolinus griseostriatus): downlist to Least Concern?
Remapping of the species’s range by BirdLife with reference to data published by Mills (2010) has resulted in a new estimate for the EOO of 85,100 km2, suggesting that it no longer qualifies as Near Threatened under criterion B1. Continue reading

Siamese Fireback Lophura diardi is listed as Near Threatened on the basis that it is undergoing a continued decline estimated at 20-29% over 10 years based on current rates of lowland forest loss in its range, as well as the effects of ongoing hunting pressure. Recent evidence, however, suggests that the species may be able to tolerate a higher level of hunting pressure than was previously thought. Continue reading
Archived 2010-2011 topics: Sula Megapode (Megapodius bernsteinii): uplist to Vulnerable or Endangered?
Sula Megapode Megapodius bernsteinii is listed as Near Threatened on the basis that the population was suspected to be declining at a rate approaching 30% over 12 years (three generations), however a high degree of hunting pressure and the observation that most of the lowland forest on Taliabu has been cleared for logging, along with observations that the species has suffered drastic declines on other range islands, suggests that the population is declining at a rate equivalent to more than 30% over 12 years, and perhaps more than 50% over 12 years, making it eligible for at least Vulnerable status under the A criteria.
