Pipsqueak

This bird keeps attacking our window, because he thinks his/her reflection is another bird.  We've stopped him from attacking one window by putting books in front of it to stop the reflection, but now he's attacking another window up high.  He stops when there isn't any sun (like now), because there's obviously no reflection without sun.  The kids have named him Pipsqueak.  I call him Pesky :)

He's messing up the window, too, as you can see above

He flies right into the window over and over!
