The folks in the Riverwalk Bird Club don't just watch birds. The group includes some excellent photographers.
Nooga.com Outdoors is happy to share their great photos by featuring a Bird of the Week.
This week, we feature a northern harrier hawk, also known as a marsh hawk, taken by Charles Dean.
—A long-winged, long-tailed hawk of open grassland and marshes, the northern harrier forages by flying slowly above the ground, looking for small rodents.
—It is one of the few raptors in which the sexes look quite different: The male is white below with a light gray back and hood; the female is mottled in browns.
—Most male northern harriers are mated to one or two females at the same time. Some males pair with up to five mates in a season. Females incubate the eggs and brood the offspring, while the male provides the bulk of the food for its mates and nestlings.
—Unlike other hawks, the northern harrier relies on its hearing as well as its vision to capture prey. The feathers of the face are stiff to help transmit sound, and it shows a pronounced "facial disk," much like that of an owl.
—The northern harrier feeds primarily on mice, other small mammals and small birds. It will, however, take larger prey, such as rabbits and ducks. It has been known to subdue large prey by drowning it.
