A huge thanks to Kristi for identifying our mystery blue bird of the summer! Turns out it's a grey catbird. Perhaps the males or females are more blue than the other because we've seen a grayish-blue one (as in this photo) and one a deeper, charcoal blue. Anyway, they are beautiful birds!
God certainly is creative. Just think of all the birds He made.
Speaking of which, Mr. Stephen Hawking, I think you are an educated dweeb.
