White patch on wing coverts sets sapsuckers apart from all other woodpeckers. Male Yellow-bellied Sapsuckers are distinguished from male Red-naped only by the red nape spot and incomplete frame to red throat of Red-naped Sapsucker. Females are somewhat easier to distinguish, as they differ in these characters, as well as having quite different throat patterns (white in Yellow-bellied, red and white in Red-naped). It is worth noting that any sapsucker in juvenal plumage after late fall must be a Yellow-bellied. Beware of rare hybrid Yellow-bellied x Red-naped Sapsuckers, and the occasional Yellow-bellied Sapsucker which may show a red nape spot.
