has a known extent of occurrence (EOO) of nearly 4,000 km2 [3,907 km2], although this value is likely to be an underestimate due to the paucity of records throughout the south of its range. The area of occupancy within that range is similarly difficult to estimate, although is likely to be quite high as a proportion of EOO due to the amount of forest still present throughout most of its range. As such, we do not currently consider this species to be of conservation concern.
