[rec.birds] Western Tanager behavior

CA.  Western Tanagers are common this time of year, although they normally
stay pretty high in the canopy.  Yesterday and today I've been having one
of them repeatedly land in a branch outside my window, fly up to the window
and bump it with his beak.  He then flies back to the branch, and then repeats
this about 10-20 times.  Then he flies up into the same tree and sings for a 
while, then comes back and repeats the performance.  I thought he might be
seeing himself in the glass but this morning when he started it was fairly dark
and I dont think there would have been any reflection.  He has done this same
behavior at 2 different windows.  Sometimes he sits on the window sill and 
looks in.  Beautiful bird.  Looks healthy, too.

Any ideas what he's up to?
