Justification of Red List category
This crow has recently been rediscovered and is listed as Critically Endangered because it is estimated to have an extremely small population, with the majority of individuals in a single subpopulation, and is inferred to be undergoing a continuing decline owing primarily to on-going habitat loss (BirdLife International 2001). Following further surveys, the species's status may need to be re-evaluated.
