CRAZY cardinal?? HELP!! 10PTS TO BEST Northern Cardinal hangs out in lilac bush outside my window singing, well the a couple weeks ago i started whistling to it. NOW every morning he/she is in the bush singing, waiting for a response which i DONT give. Sometimes during the day ill whistle back, but it really seems like he/she is around the house 10 of the 12 hours of daylight. Is it lonely or? It also keeps slamming into this ONE window (right below mine), which thankfully has a screen over it so he/she just bounces off and hangs out in the tree. This has been going on for months and i just wanna know whats going on with this bird!! If it helps, the flying into the window thing started BEFORE the whistling/singing.

Animals like routine. Also the bird might be a little slow... Maybe it likes the smell of fresh lilac in the morning dew.
