Justification:

Corvus moneduloides is endemic to New Caledonia (to France) and has been introduced to the neighbouring island of Maré (Loyalty Islands (to France)). It occurs in forests throughout these islands, and is locally common on New Caledonia. Its present status is unknown on Maré where it was very common in the 1930s. Although it is a forest species it has been reported from niaouli savanna. It usually forages in pairs or family parties, but flocks of up to 30 have been seen. It is omniviorous and has a unique habit of using tools to extract food items from holes and crevices. The clearance and degradation of forests across New Caledonia is a threat to this species. No specific conservation measures have been implemented but populations occur in protected areas such as Rivière Bleue Park (Warner 1947, Hannecart and Létocart 1980, G. Dutson per. obs. 1999). This species has an estimated global extent of occurrence of less than 20,000 km², but it is not believed to approach the thresholds for the range criterion of the IUCN Red List (i.e., an extent of occurrence of less than 20,000 km² in conjunction with both severe fragmentation and fluctuation/declines). The global population size has not been quantified, but it is believed to be large as the species is described as 'common' in at least parts of its range (Madge and Burn 1993). Global population trends have not been quantified, but populations appear to be stable (Ekstrom et al. 2000) so the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e., declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.
