Birdi at Work
This photograph of an English Sparrow was created outside a shed in my backyard. I hid in the shed and ran a cable release to the camera on a tripod placed next to the bird feeder. I observed the birds through a crack in the wall of the shed. At first the birds did not come to the feeder because they knew I was in the shed. If I left the shed then they would return. So I had my wife enter the shed with me then had her leave. The birds then returned to the feeder because they thought both of us had left. They saw someone go in and someone go out but they can't count.
