A well timed image. I am curious how they manage to pry open the shell?
Nice color, exposure and low angle of view.
A foot to your left or some might have improved the angle on the head slightly, but there was still going to be a bit of angle away from you because of the plane of the shell in relationship to the bird. This is a pretty small point of course.
I do appreciate the images that tell us something about the life of the critter featured!
Great angle, details and exposure control. I also like the captured moment. I might tone down the legs and remove the oval spot underneath the legs near the frame.
