I would like to contribute one more little tibbit of information: Birds can't count.

If you set up a blind close to a bird feeding station from which you want to shoot photos and you would like for the birds to return as soon as possible then take someone in with you. When that person leaves the blind then and since birds can't count, they think the blind has been vacated and will return.

Unless our Adair County Birds are more highly educated than others around the world this should work for you.-Billy Joe Fudge
