A little excitement on a Sunday morning

I was looking out the kitchen window this morning, enjoying the calm, fall morning and admiring the beautiful tree in our backyard---loved it so much I actually took this picture this morning!
All of a sudden, a hawk flew into our tree and started going after a squirrel that was climbing the tree! It was so exciting!! The squirrel kept running away and hiding from the hawk.

Eventually the hawk gave up and flew away!
