Jeannie and others,
Another good thing to do is to check Cornell's web site all about birds: http://www.allaboutbirds.org/NetCommunity/Page.aspx?pid=1184
If you follow this link they explain what is happening at your house and various alternatives to protect birds from window collisions.
this spring we watched a robin at a relatives house do the same thing. It is disturbing but probably will not harm the bird.

Once this spring and now this summer I witnessed odd bird behavior that I am
not sure what to think about. It involves a bird precariously perching on
or near a window frame and then flying continually at the window panes
themselves, as if it is trying to get in. This Spring I saw an American
Robin do it. Over and over and over again.from perches right on the
frame..and from perches a few inches away, tapping against the second story
window. There were plants inside on the window sill. So first I shut off
the lights, no change. Then I moved the plants out of sight, no change.
Finally I put a towel inside the window frame and the behavior ceased. This
morning a Male Common Yellowthroat is doing the exact same thing, at a
different window, this one on the first floor. It has been going on for at
least 20 minutes, and since my husband saw the bird on a nearby post over
the past few days, I wonder if it has been going on for that length of time.
Any ideas on what this behavior is and whether I should be worried for the
