The Bird

We've had this female cardinal bird flying & pecking at the windows on our house for a long time now.  I tried to figure out when she first started and I thought it was early spring this year but it could be as far back as last year early spring.  When we're watching TV, we can here her flying into the windows with a thump.  She doesn't fly hard enough to knock herself out or anything, just hard enough to annoy us and she poops all over the place.  We think she sees herself in the glass and  she's mentally challenged.  We've tried to figure out ways to get her to stop.  We moved the bistro table & chairs away from the atrium window downstairs.  We moved the rocking chairs away from the windows on the deck.  We placed fake birds on the railing of the deck.  We moved things off of the windowsill.  Jim has tried shooting it with his BB gun and, fortunately, hasn't shot any windows out.  The bird seemed to go away for awhile but now it's back.  When I came downstairs yesterday morning to go to work, I heard the bird flying into the window on the deck again.  Jim shooed it away and we left.  When I got home from work yesterday, sure enough the bird was flying into the window.  I couldn't believe it and said (to the bird) "Have you been doing that all day, you stupid, bleeping bird?"  Of course there was no answer & I felt like the mentally challenged one!  So my questions are:

1.  Does anyone know if cardinals fly south for the winter?
and
2.  Does anyone know the lifespan of female cardinals?
