- Fakta menarik
- The Northern Harrier is the only North American raptor with an owl-like facial disc, which channels sound to its ears and lets it locate hidden prey by hearing alone.
- Sebaran
- Breeds across northern North America (Alaska/Canada to the northernmost U.S., Great Lakes/Plains); winters south through the continental U.S. into Mexico and Central America; some populations year-round in parts of the Midwest/mountain West.
- Makanan
- Mainly small mammals (especially voles, cotton rats, ground squirrels — up to ~95% of diet) and small-to-medium birds (up to flicker/small duck size), plus amphibians, reptiles, and large insects (e.g. grasshoppers); occasionally carrion in winter. Hunts by coursing low over open ground, using hearing to locate hidden prey.
