European green woodpecker It also occurs in western Asia. The European green woodpecker has a large range and an Estimated Global Extent of Occurrence of between 1 million to 10 million square kilometres, and a population in the region of 920,000 to 2.9 million birds. Populations appear to be stable, so the species is considered of Least Concern. The species is highly sedentary and individuals rarely move more than around 500 m between breeding seasons.

There is no evidence to suggest that it occurs in Caatinga. Rather, the authors who proposed the common name Caatinga woodpecker and association it with the caatinga habitat mistook a place in the caatinga called Uruçuí-Una for
