Northern Harrier Watching in Oregon

The Northern Harrier, sometimes called a Hen Harrier or a Marsh Hawk, is a large bird of prey that is found throughout most of North America, including many parts of Oregon. Females are generally about 50 percent larger than males, and their colorings are quite different as well. They are known for being unusually vocal while they hunt, so this is often the best way to find them.Northern Harriers prefer to feed on mice or other small animals, and occasionally small birds as well. It's usually best to look for them during early morning or evening hours, and binoculars or a spotting scope can help greatly. They fly with a shallow V shape in their wings, typically not far off the ground.

Habitats for Northern Harriers

Northern Harriers nest on the ground, usually in grasslands or marsh areas. They prefer open areas, often wetlands, wherever rodent populations are large enough. They are commonly found in the Tualatin National Wildlife Refuge, though not in equal numbers throughout the year.

Best seasons to see Northern Harriers in Oregon

While some Northern Harriers have been known to live in Oregon all year long, they are most common during the fall. In the eastern part of the state they are known to breed and live in the same place, but along the southern Oregon coast there are many who are only around during late fall and winter.
