Yeah, I got the first impression that it might be a juvenile RTH too but the 4 fingers on the wing tips made me think again. And Eastern Red-tailed Hawks can be very light colored but this one, if it was a RTH would have to be very leucistic, almost an albino. That's when I pulled out my copy of Ligouri's book. The bird in the photo 1st cited is unmarked, much like this bird and show 4 fingers on it's wing tips. Red-tails have 5 prominent fingers on their wing tips.
