Great Spotted Woodpecker: adult male ID

The main distinction between adult male and female Great Spotted Woodpeckers is the presence of a bright red nape patch on the male, which the female lacks. The males black crown often has a rather bluish sheen and, as with most woodpecker,s the male’s bill is heavier though this is not really noticeable in the field.
