Thanks for the comment! It is very interesting! I read about this Black-backed Woodpecker in the Wikipedia. He looks funny :)
Haha. Well, it's understandable why they like burnt forests. We have in the middle of spring, the forest in which I often go, the grass is burning in it, and the fire passes to all sorts of hemp and logs. And the birds are very fond of digging in all this burnt . They love fried insects, which do not have to be caught, just saw and ate.
