Apparently this robin fledgling (one of three) passed away and the mother pushed it out of the nest, but it got stuck. We were able to get rid of it without scaring the other two babies, but they left the nest the next day. In spite of the farm kitties, we still see the babies doing ok in the grass with their parents still nearby.
Since we can't see too well, we took this little video to review and make sure the hanging bird wasn't still breathing.
