Being that it's "huge" and that it's this time of year, I would guess a pale, semi-albinistic or albinistic FERRUGINOUS HAWK. They vary from palest brown to almost pure white. They are winter passers and stay around from January into April. The link I'm attaching shows some dark forms as well as almost white forms. Joe Here is a link that might be useful: Ferruginous Hawk

I had my very *first* juvie sharpie yesterday in my yard. I was very surprised to see just how petite and gangly these guys are! I was mesmerized.

I found this post after I had posted on the "pets" forum the following: "We have a pup, 2 1/2 months old, weighs 8 lbs. We live in the middle of woods in a very rural area. She loves being outside and is gradually exploring further and further from the front porch. We have all kinds of wildlife here, but my main concern are the owls and hawks. Are they a danger to an 8 pound pup? I can't seem to find a definite answer online about this, varying opinions everywhere. We have barred owls and great horned owls, which are pretty big. We also have red-tailed hawks. At what size do we not worry anymore about the pup? We also have seen racoons, foxes, bobcat, and have been told we have coyotes, but I've never seen one. I'm not as concerned about those because they pretty much stay away from the house. Our property is big but is fenced with field fence all around." All the answers on that were "be concerned". I'm seeing both sides to this here. So I guess to be safe I'd better keep a close watch until she gets to be around 15 pounds, which should be in about 6 more weeks.

Most hawks do migrate to areas south of their summer ranges. Red tailed and swainson's sometimes migrate to places in south america. Falcons as well are long distance migrants. Thousands of broad winged hawks migrate as a "kettle" that is a large group, and hawk watchers can often observe this behaviour in late fall at various places throughout north america.
