David and tweets,

I have a friend with a similar problem with a robin. We thought that a
mirror placed closely to where the bird is attacking the window image
might make the bird chose the mirror image rather than the window.
Haven't heard what his results have been but it might be something to
try in your friend's situation as well.

Perhaps the behavior will wind down on its own as hormones levels
change.

Good luck,

Paul
