Molly, I can see the fence in the background, so I figure these are captive birds. So, my advice, is to spend a bit more time, try to isolate one bird (or get both if possible), and try to shoot so that you can't see any sign of the fence in the background. Zoos often offer great opportunities to do close portraits or simple, pure head shots. Keep shooting, and try to make your zoo shots be real enough looking so that people won't be able to tell it is a captive animal.
potentially such a great shot here, you didnt say where this was, birds in captivity or wild? Just a few suggestions: dof would need to be increased - to me everything in this image should be in sharp focus, and i notice the two birds are not. the composition is good to me, although moving over to the right would get a little more detail on the fg eagle, and to include all of the eagle in the frame. nice attempt however :)
