Early this morning, I was awakened by the repeated sound of birds flying into our picture window. After scouting the back yard for avian corpses (there were none), I decided to do something about it.
Just now, I finished drawing this design to cut out and paste onto the window as a bird deterrent:
It's not my best art ever, but I hope it's realistic enough to convince the birds that our glass window is not made of sky at all. This time of year, the sun shines just right to make our windows reflect the forest behind the house, and the birds must think that they can fly there.
I made a reference diagram by mashing a stuffed toy chicken into my scanner, and then I rotoscoped it.
