This fellow forages high in the canopy but it will perch in the open.
He is quite LOUD with his whee-eep call. They are quite common in deciduous or mixed forests during breeding and can be found across the east and central US.
Up north I had to travel to the woods to see them but here they are everywhere.
Hopefully I'll get a color photo for you after you guess from the silhouette!
Good luck to you and wish me luck too!
