Yeah, a longer lens would help.
For me, my opinion, and view point, is that if you took a picture and filled the frame with 1 or a couple turkeys poking their heads out, we would see details of them, and still get that they are hiding. The image would be all about that. But in this image posted, it appears to be a landscape shot, and I am drawn to investigate the interesting stuff in the upper right. The colors, the softly undulating lines...that's what my mind thought this image was about. The bird heads are such a small infinitesimal player in this scene, that they barely register.
