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.
Palm Crow Corvus palmarum is listed as Near Threatened under criterion B1a+b(iii,v) on the basis that it was considered to have a moderately small range in which habitat degradation and hunting are causing a population decline.
The species’s Extent of Occurrence (EOO) has recently been updated by BirdLife and the new EOO is estimated at 103,400 km2, which no longer approaches the threshold for Vulnerable under the B1 criterion; this suggests that the species is eligible for downlisting to Least Concern.

Evaluation of the threat level for this species is hindered by an apparent lack of data on population trends. Nevertheless, it is currently suspected to be declining at a slow to moderate rate (1-19% over 10 years), on account of hunting pressure and forest loss (Madge and Burn 1993, Latta et al. 2006), and, perhaps on Cuba, competition with Cuban Crow C. nascius (A. Mitchell in litt. 1998). The accurate assessment of the status of C. palmarum is also hindered by an apparent lack of estimates for its population size.
Up-to-date information is requested on this species’s likely population size, current rate of decline and the severity of threats to help in the assessment of its status. Improved knowledge of the species’s life history means that the rate of decline should be estimated for a period of 22 years (estimate of three generations).
