This was the accompanying email with hint:
I took some pictures of birds this weekend and I have attached the first one for you to identify.See if you can find him in your bird book! When you do you can call me or write to me and tell me what his (very silly) name is.
There are some good bird identifying sites to help you here:
We were given this book to help us. I'm sure you can find a bunch at your local library too.
See if you can figure this out! Let me know how it works for you. Once I figure out how I'll post the work sheet I made to go along with it.
