Pictures kind of blurry but it kind of looks like a domesticated duck, or an egret but it looks more like a duck. You might look for a picture of a snowy egret being that you saw the bird and would be able to match it a little better because of the image quality.

Shiverfix, How did you ID that as a Swainson's from that angle/pose? Can't see the bib, nor the dark leading edge on the wing! I'm curious as to how you can tell Swainson's from a Kreider's variation of a redtail from a ferruginous (light morph) or any other buteo from that angle?

Tbub, now that you mention it, I could see the argument for a red tail. I was mostly going by shape and lack of mottling or belt , because you cannot see the bib. I don't think it is a ferruginous, and if you were to ask me why, I could only tell you it just doesn't look like one to me if that makes sense.
