Ronald Walters | Mailbox Spinner - Keep The Birds Away @RonaldWalters2010 | Uploaded December 2020 | Updated October 2024, 1 hour ago.
Designed to keep birds away from my mailbox. The birds are leery of something that moves by itself and they stay away from it. If they do not perch there, they do not make a mess on top of the mailbox. Has proven to be very effective.
