What kind of bird of prey has a blue beak?

It was perched on a telephone wire (and not a very high one) over a meadow's edge just outside of Buffalo, New York. It seemed to be some sort of bird of prey. Its beak was bluish, almost turquoise, and hooked. It had a pronounced white bib, almost like a ruff. It had its tail fanned out as it sat and the under side of the tail was very pale, perhaps white. It had brownish-grey feathers on its back and wings. And the feathers on its head looked almost as if they had been "blow-dried" back. It seemed bulkier than the hawks I've seen, but not exactly owl-like. The feet appeared to be dull brown or gray and there were no "pantaloons" visible. Any ideas?
