Wayne said "Well that's a bid woodpecker!" So I rushed to the window to see a hawk perched on top of one of the feeders. Guess it couldn't forever ignore the clamour of sparrows at lunch time' I made it known his presence was unwelcome and he flew off to a high oak tree branch and watched for a while as I watched back. Will readjust feeder placement to give even more protection from over head or easy swoops. Hawks around here usually hang out along the main highway....first I have seen in my yard.
