Funny - in a sad kind of way...

This past Spring, I kept walking out into the studio and finding similar imprints on any one of my four large eastern facing windows. At first I thought maybe the birds couldn't see the window and were trying to fly into the studio (kind of like a Windex commercial); but I later came to think that the birds were seeing themselves in the reflection of the window and thought they were being challenged by a competitor. I haven't seen any imprints since Spring; and I so I think all of this took place during mating season (that's my National Geographic hypothosis), when the birds were staking out their claim for a girlfriend!
