(Clearwisdom.net) During the summertime, I sometimes sleep in a bedroom that has a large window overlooking a wooded area. I am often awakened by the sound of a bird, a red cardinal, crashing into the window early in the morning as the sun rises. The bird deliberately flies into the window, hitting its head really hard. The bird then takes a minute sitting on a banister close to the window, apparently to clear its head, and then attacks the window again. It does this several times a day. From my vantage point behind the window, I have observed the same behavior with several generations of birds over the years. Indeed, about 15 years ago, a predecessor of the same unfortunate bird (also a male red cardinal) crashed into the same window so hard that he was knocked unconscious long enough for me to get my camera and photograph him sitting on my young son's hand. When I first witnessed this strange phenomenon, I concluded that the bird must be crazy. However, my friend, an avid bird-watcher, explained to me that the bird was seeing his own reflection in the window glass and, believing that rival male red cardinal was encroaching upon 'his' territory, he was attacking his own reflection intending to scare the 'other' bird away.
