Is it a Red-tailed? It was totally white underneath when it flew away. No stripes or anything.
In La Crosse WI and was bigger than the crows.

Young Osprey show white on the wings and at the distance of this shot, the blur could show as a patch. The stance and shape look more like an Osprey to me than a Red-tailed. I'm not sure definite ID on this photo is possible.
This is a Red-tailed Hawk. The pale scapulars and shape are diagnostic.
EDIT: I would expect to see a RT perched in a more vertical manner, but I have seen Osprey in this position very often. If the position is due to eating prey, then again Osprey would be the bird of choice.

You must have an awesome screen and maybe that allows you to be so positive. I only have a small lap-top and this very distant shot shows no detail on the face for me. As I mentioned a juvie Osprey shows white and at a great distance, with distortion, could appear as this bird shows. Here is a photo that shows what I mean:
Sorry, but this is still a Red-tailed. The white on the wings of a young Osprey is the result of pale feather edges -- it's spread across the wings and back, and wouldn't concentrate. A Red-tail is perfectly capable of holding this pose for a short time, (which illustrates the potential problem from using posture in photos). An Osprey should be distinctly longer tailed, more evenly colored across the back, and with a distinct eyeline on the face.

On a different note, the taxonomic status of kriderii is rather up in the air -- AOU does recognize it, but Brian Wheeler and Bill Clark both claim it's just a color morph of borealis. Given that you can find typical borealis breeding in the same locations as kriderii, I tend to agree with Wheeler and Clark -- the usual definition of subspecies involves a geographic region where you find just that subspecies, frequently with an intergrade zone where they meet another subspecies. That doesn't fit kriderii.

I never see Ospreys in places like this, they are nearly always associated with bodies of water.
I agree with Red-tailed, this may be a Krider's subspecies (B.j. kriderii).
I wasn't aware there wasn't water nearby. I have seen the Osprey here (Panama) take prey to a high point far enough from the beach that if I took a shot, water would not be visible.

I wouldn't say I've got a great monitor -- just a lot of experience looking at hawks. The last 12 autumns, I've spent 4-5 days a week (occasionally more) counting migrating hawks at a couple of locations.
I admit that my last 12 years have been in areas other than North America for the most part. I have come home to Ca a few times and I have breeding RTs on my property so I have had a few opportunities to see them there and other places in CA. I've never noticed a RT with legs quite as long as the bird in the photo. As I said, I would not give a positive ID on this photo, just throwing out what I was seeing, but I haven't spent time in the US on a raptor counts.
