This photograph shows an adult male Northern Harrier (Circus cyaneus). Northern Harriers are one of the few raptors that show readily recognizable sexual dimorphism. Males have gray topsides and black wingtips while females and juveniles are browner. The ventral surfaces of males' wings are light colored with dark trailing edges on the secondaries. Both sexes have a light facial disc which aids in hearing and a distinctive white rump.
