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. A combination of old deciduous trees for nesting, and nearby feeding grounds with plenty of ants, is essential. This is usually found in semi-open landscapes with small woodlands,

Most of Cuba's lowland deciduous forests had been cleared by the early twentieth
