If you are attempting to photograph birds from a blind, you may need a companion to enter the blind with you and leave momentarily. Many birds have fantastic eyesight, if they notice you enter the hide they will wait for you to leave before approaching. If they see your friend leave, and will assume that you have left and continue with their normal routine. However, some birds such as hawks, eagles and falcons can count.
