The birds...

I was sitting quietly in my living room reading a book (miraculously, all three of my kids took a nap today!) when I heard a mysterious scratching sound on my roof.  It didn't go away but intensified over the few minutes I pondered the sound.  Then it was accompanied by a chirping that slowly began to envelope any other thoughts in my mind. I slowly pulled back my blinds to find the source of the interruption and saw a magnified version of this:

 

The sound of the blinds brought them out of their stupor causing immediate flight. It was like a blanket of black waving from my roof and grass to the neighbors roof and fence.  

A little too Alfred Hitchcock for me.
