Grapevine Discovery

I have a beautiful American Robin nesting in one of my grapevines. Over the past month I've watched her build her nest using branches and twigs from my backyard. 

This morning I took a peek and discovered this...

 

If you look closely you will find 4 eggs - 3 in the middle and one off to the side.  Momma bird sat on the fence and watched me look at her eggs.  When I went back into my kitchen, she flew back into her nest.  

I can't wait to see her babies.
