Whacky Robins

In the family room, we have 5" tall windows that sit above the ground about 10".  In the spring, it's nice to have these open to the refreshing breeze.  This year, however, they have become ground zero for robins.  For several hours during the day, robins dive bomb the windows, often grabbing the screens for support.  Having never witnessed this before, it was like living through Hitchcock's bird scenes.  After watching closely one day, we realized the robins were feeding off the baby spiders hatching in the moulding around the screens.  Thanks to the robins voracious appetites, our family room will be spider-free this year.
