Go with #1. The first one tells more of the "story" than does the second one. The bird is back lit so there is not a lot going on in the bird`s face anyway. The first photo looks as if the bird is standing on natural rocks. The second photo looks more like riprap below a dam or something. In the first photo we can see the mist comming off the rocks as the sun warmes them up. This is lost in the second photo.
Yup, Number 1 for sure for all the reasons Sandi said. It is funny how many times people are split on picking an image but here it is very clear. The first one captures the mood and scene so much better. A good example for us all to see. Well done.
