Staartmees/Long tailed Tit - They travel in groups but rarely come into the garden preferring to feed on buds and insects on trees.recently I've a few coming to feed on the feeders hanging in the yard :)
European Green Woodpecker, one of four subspecies, occurs in most parts of Europe & western Asia. Spends much more time feeding on ants & does not often 'drum' on trees. File:RO B Carol Park green woodpecker crop.
Blue Tit: these birds are often found in England and are therefore good bird to build a house for. Yet the Eurasian blue tit prefers insects and spiders for its diet. This therefore makes them harder to feed and return to the bird box.
