Anytime a slim, long-tailed hawk is observed hugging the terrain as it glides over grasslands, marsh and field, I instinctively think “Marsh Hawk” and go from there. This is a slender, graceful predator with a very long tail, unique even in silhouette. But it is the Harrier’s distinctive white rump that often confirms its identity.
Not much of a photo, I’ll grant that. And yet with that very long tail and white rump patch, there is no doubt that this is a Northern Harrier gliding through the Chignik River valley. (August 29, 2016)
I’ve encountered Northern Harriers (formerly Marsh Hawk) in a number of states, from Florida to Oregon and north to Arctic Alaska. Although they are widespread and might be found anywhere their preferred habitat exists, they generally aren’t abundant anywhere. On the Alaska Peninsula, they’re rare, although they are known to breed out here.
That white rump is diagnostic. Note also the almost owl-like facial disk. Like owls, Harriers rely on a keen sense off hearing to detect the small mammals, occasional birds and other animals they prey upon. (Photo Credit, Dan Pancamo, Wikipedia)
This is exactly the kind of habitat Northern Harriers prefer. I encountered this specimen near Point Hope, Alaska, an Inupiat village located 200 miles north of the Arctic Circle. This kind of terrain is a good place to make a living on voles and lemmings. (September 3, 2011)
