The Northern Harrier is distinctive from a long distance away: a slim, long-tailed hawk gliding low over a marsh or grassland, holding its wings in a V-shape and sporting a white patch at the base of its tail. One occurred in east central North Dakota while conducting my graduate wildlife research project. As might be expected, most reports during the breeding season are from the Panhandle and Sandhills, where extensive marsh habitat and grassland exists (Mollhoff 2016). During the survey, they not only found evidence of the rare moth, but also discovered a northern harrier nest! Nesting. out of the nest to meet the male and he gives her the prey in mid-air. Use of Study Area Resources: Reproduction and wintering: Maine, New Hampshire and Massachusetts are all within the breeding range for northern harriers. A Northern Harrier flies low over the grasslands with a flock of Red-winged Blackbirds following it.

And any possible predator near a nest better watch out! Litter cover Map courtesy of NatureServe (2004). North American Breeding Distribution and Relative Abundance: Distributed across Canada, the northern United States, and the western United States south to southern California, northern New Mexico, and northern Texas. nesting northern harriers, the creation of buffer zones surrounding nest sites is a possible solution (Serrentino 1992). Some 12 Hen Harrier nests have been reported on northern moors this season by the Moorland Association (Alex Shepherd). Easily recognized by its flying patterns, dihedral positioned wings, as it swoops and glides just over the tops of marshes and fields, falling upon their unsuspecting prey, unlike most raptors that dive from higher heights. Commonly mobbed by blackbirds, sparrows, starlings, swallows, kestrels, Short-eared Owls, Sharp-shinned Hawks, and other birds, the raptor decides the annoying harassers are too swift and maneuverable to put out the effort of trying to catch one.

The Moorland Association has reported that 12 Hen Harrier nests have been discovered on moorland estates in northern England – a figure that would match the total number of successful nests throughout England last year.. Training of land managers to identify the species as well as recognize suitable habitat North American Breeding Distribution and Relative Abundance: Distributed across Canada, the northern United States, and the western United States south to southern California, northern New Mexico, and northern Texas. And any possible predator near a nest better watch out! Of the 13 species of harriers that occur worldwide, the Northern Harrier is the only one that occurs in North America.

Harriers typically nest on the ground, either alone or in loose colonies. The Northern Harrier was a common species during the Minnesota Breeding Bird Atlas (MNBBA). Mid-air food exchanges helps keep the nest hidden from predators. She then returns to the nest to feed the babies.

out of the nest to meet the male and he gives her the prey in mid-air. Summer: Northern Harriers may nest anywhere in the state where wet meadows occur (Ducey, 1988, Mollhoff 2016). Up close it has an owlish face that helps it hear mice and voles beneath the vegetation.

The nest is a platform of sticks and grass. When I think of the northern harrier, also called marsh hawk, a couple of experiences come to mind.
