Hey all

Walking in a local park near home, saw this one fly by, the flash of white caught my eye.  Followed it over to a tree where it very cooperatively let me take quite a few pictures as I inched closer and closer...but I'm not sure what it is.  My guess at the park was northern mockingbird, but when I got home and looked in my bird book, I wasn't so sure.

Help greatly appreciated.

I agree with mockingbird with the white on the wings and tail.  He's looking a little rough...
