Gallery: Black Woodpecker nestlings

Black Woodpeckers can be visually sexed when still in the nesting cavity, i.e. before they fledge. As with adults, fledgling males have complete red crowns whilst fledgling females only have red on the hind crown. Thus, the top bird in this photo is a male. The sex of the lower bird is unclear due to its crown being out of view.
