I'm guessing this is either a Sharp-shinned or Cooper's Hawk based on small size and color but I am no expert, just a backyard bird watcher. The two photos show different colors as one was taken in the sun and the other when a cloud passed overhead. It landed on the deck twice, took off and I haven't seen it again. Date seen was Jan. 21, 2021, Location is Glen Allen, Virginia, U.S.A. Thank you in advance for any information or ID. It is very much appreciated! (click on the attachment to enlarge).
