White-backed Woodpecker: juvenile male ID

Juvenile male White-backeds have an all red crown which extends at the back of the head to the black nape and sideways to the white cheeks. This becomes apparent around twelve days after hatching and is more pronounced as birds peep out of the hole prior to fledging. Male fledglings are generally heavier, and have longer bills and tarsi than sibling females though these factors only noticeable in the hand.
