I'm with Richard. The longer I've been doing wildlife and nature photography the more I'm drawn in my own work to more "environmental" shots. In the past 10 years or so, I've gone from the "darn happy to get one that is in focus" mode to more critical of my own work. I do like to portray the wildlife in their environment (context as Richard accurately called it). To me it tells more of a story. What was it doing, why was it there, where was it and where does this critter live. Some tell the story of the daily struggle to survive and some are just doing something interesting.
I like the wider cropped image better. In fact, if you have even a little wider cropped image that shows more reference for how large the eagle is (surprisingly there are a lot of people who have never seen one) or more context around where it lives (the water) then I'd probably like that one too.
Bottom line, it is a personal preference. Both photos you posted work.
Hope this helps.
