Archived 2015 topics: Venezuelan Wood-quail (Odontophorus columbianus): request for information

This discussion was first published on Dec 2 2010 as part of the 2011 Red List update, but remains open for comment to enable reassessment in 2015.

BirdLife species factsheet for 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. In particular, information on the level of habitat fragmentation and number of locations occupied by the species will help in the assessment of its status. Its habitat would be considered severely fragmented if over 50% was in patches too small to support viable populations. With regard to the IUCN criteria, the term ‘location’ “defines a geographically or ecologically distinct area in which a single threatening event can rapidly affect all individuals of the taxon present. The size of the location depends on the area covered by the threatening event and may include part of one or many subpopulations. Where a taxon is affected by more than one threatening event, location should be defined by considering the most serious plausible threat” (IUCN 2001).

  1. Joe Taylor says:

    Preliminary proposals

    Based on available information, our preliminary proposal for the 2014 Red List is to pend the decision on Venezuelan Wood-quail Odontophorus columbianus and keep this discussion open until early 2015, while leaving the current Red List category unchanged in the 2014 update.

    There is now a period for further comments until the final deadline of 31 March, after which recommended categorisations will be put forward to IUCN.

    The final Red List categories will be published on the BirdLife and IUCN websites in mid-2014, following further checking of information relevant to the assessments by both BirdLife and IUCN.

  2. Andy Symes says:

    Recommended categorisation to be put forward to IUCN

    Following further review, there has been no change to our preliminary proposal for the 2014 Red List status of this species.

    This discussion will remain open for further comments and information until early 2015, and the current Red List category will remain unchanged in 2014.

    Preliminary proposals

    Based on available information, our preliminary proposal for the 2015 Red List would be to continue to treat:

    Venezuelan Wood-quail as Near Threatened under criterion B1a+b(i,ii,iii,iv).

    There is now a period for further comments until the final deadline of 31 August, after which the recommended categorisation will be put forward to IUCN.

    The final Red List categories will be published on the BirdLife website in late October and on the IUCN website in November, following further checking of information relevant to the assessments by both BirdLife and IUCN.
