Hubby noticed Pericles (one of our Siamese cats) sitting in the window sill tonight.  Nothing unusual about that, but on the other side of the glass was a mourning dove looking in the window at the cat.  A few hours later, Pericles was gone from the window sill, but the dove was still there, knocking on the glass.  It took a few tries, but Ajax (another of our Siamese cats) made it into the window and is not keeping the bird company.  The bird is snuggled against the window on the sill, contentedly keeping company with either cat.

I hope neither the bird nor the cats figures out how to open the window.
