Japon Ağaçkakanı Picus awokera

The only green-backed woodpecker in the region, found in deciduous and evergreen broadleaf forests in mountains. Plumage unmistakable, with green upperparts and numerous neat spots on the belly. Gives distinctive, robust “pyo pyo” whistles, in addition to “kyo kyo” calls extremely similar to some other woodpeckers. Drumming is fast and long.
