An Intergrade Northern Flicker is an inter-species mix of Red-shafted and Yellow-shafted Flickers. Red-shafted Flickers are indigenous to the western North America and Yellow-shafted is an eastern subspecies. Male Red-shafted flickers have red malars (moustaches) and a redish to orange underwing and undertail, where male Yellow-shafted Flickers malars are black and a yellow underwing and undertail. Both male and female Yellow-shafted Flickers have a red crescent on their nape which is lacking in the western subspecies. The photos below show a varied mix of predominance of each of these characteristics.
