I think this might be a Common Black Hawk, Buteogallus anthracinus,
(although it lacks the broad white terminal tail band)
as portrayed in tiles on the walls of the West 77th street entrance to the NYC subway stop (A-B-C)
at 81st and Central Park West. (ISO, no zoom, no flash).
Very nice indeed! My favorite mosaic so far. The long Turkey Vulture-like wings look rather Zone-tailish, but again the tail markings are a problem. Guess we'll have to chalk that up to artistic license.
