Papuan harrier Circus spilothorax

A common patroller above reedbeds, flying with wings raised in a shallow V-shape. Adult males are predominantly pale gray with a dark-speckled head, blackish back with pale-edged feathers, and black wingtips. Adult females are brown and streaky and lack the bold white rump patch of the similar female Hen Harrier. Juveniles are brown with paler heads and breasts. Extremely similar to Eastern Marsh-Harrier, but no range overlap.
