A blue jay squealed and all the birds went quite, so I knew something was soaring overhead. Found 2 small/medium hawklike birds moving very fast. At least one appeared to have a white head and a black tail or at least the end of the tail was black. Thought they might be kites, so ran in for camera and only got one usable shot. Mississippi kites have been seen around here lately. Is that what I have here?
