The cap looks grayish... for s Catbird, I would think it should be darker since those feathers have pigment. Plus the under wing pattern looks like a mockingbird(just reversed).
@The Bird Nuts I agree it is not a Phoebe. As far as a crest goes.. are you talking about the last pic? I am not sure that is a crest or just some windblown or out of place feathers. Another thing is...in the second pic, it looks like a yellowish eye.
