This feeder is not 10 feet outside my husband's study window. Dan was practicing the guitar at the time and the deer was obviously listening but not frightened in the least. When I stood at the window to take the photos it could see me but again it wasn't frightened away. It was set on feeding on the sunflower seeds. Dan said that on Wednesday as he worked at his computer the deer was there eating too. It emptied the feeder then.
