If you know your Birds...the tell TAIL MARKINGS are here

I went for a walk today with the binoculars and camera and NO DOGS.
I was lucky to capture this bird in the tree for a long long time.
I have many shots of him, but the one shot of his tail up in the air, the way they characteristically can hold them is very blurry.
Here is is anyway.

Do you know what Bird this is? Please get out your flash cards!
