The Red-shafted Flicker (the western subspecies of N. Flicker); Hybrids with Red-shafted are known but are very uncommon, probably because Red-shafts do not breed in deserts but in pine-oak woodlands. Gilded Flickers differ from Red-shafted Flicker in bright yellow underwings, warm cinnamon crown, oblong spots on lower belly and flanks, and more black on rectrices when viewed from below. The Red-shafted has reddish underwings.
The Northern Flicker is a large terrestrial woodpecker found throughout North America, provided there are trees near open patches of ground for foraging ants, which are their main food item.
Males are similar to females other that a red malar mark.
Northern, Gilded, and Red-shafted Flickers do interbreed where their territories meet. However the zone in which they interbreed seems to be stable in those area rather than spreading.
