Hi Steve, just watch the blacks in & around the eye, don't let it clog/fill in so you loose detail. A quick fix is if you import your image as is into LR or ACR and change the WB to Auto the colours look far better and it takes out the slight 'saturation' overall.
Steve, we call them Owl pellets, which, as you quite rightly said, the owl regurgitates every now and then, stuff it normally doesn't pass. A great source of information contained in them and they can be quite large too. If you find one it will probably be dry, just soak it in a container of water and you will then start to see what it has been hunting, small claws, skulls, bones...
Is the Hydro to your right with the sea to your left, if so I know it thanks to another BPN member. If you are around next year we may bump into you.
