LC
New Caledonian Crow Corvus moneduloides

Justification
Although this species may have a restricted range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Distribution and population
This species is endemic to New Caledonia (to France) and has been introduced to the neighbouring island of Maré (Loyalty Islands (to France)).

Population justification
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).

Trend justification
The population is suspected to be stable in the absence of evidence for any declines or substantial threats (Ekstrom et al. 2000).

Ecology
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.

Threats
The clearance and degradation of forests across New Caledonia is a threat to this species.

Conservation Actions Underway
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).
