The Northern Harrier is the only harrier found in North America.
The female and male Northern Harriers have different plumage.
The male is white and gray, the female brown.
A great field marker is the white rump which is obvious in flight.
Besides using their eye sight to locate prey,
Northern Harriers use their sense of hearing.
Their owl-like facial disk aids this.
