One thought on “Javan Yellownape (Chrysophlegma mentale)”
The population is indeed likely >10.000 individuals. The mountains and forest fragments with eBird records on Java and Bali add up to a forested area of 4328 km2. For the closely related Checker-throated Woodpecker in West Borneo, Lammertink (2007) found a mean density of 2.9 ind /km2. If the density is the same in Java, that works out at 12.551 individuals just in the areas with eBird records. Adding areas without current records but with suitable habitat, the population should exceed that minimum estimate. The bird market capturing of this species is not targeted at it and is unlikely to have a significant impact on its population.
