Adult female Three-toed Woodpeckers are on average lighter and slighter than males, differences in size between the sexes are not obvious in the field. Lack of yellow on crown, which is blackish and flecked with grey or white, is the best feature for separating females from males. The photo here is of adult female tridactylus race in Sweden (Göran Ekström). Note the greyish rather than yellow crown.
