Thanks for all of your suggestions. After looking at my tracings some more and a bit of googling I am convinced Lazy8 has it, a Vulture or Buzzard depending on how you call things. What we can see is the wings, body, small tail feathers, legs (but not feet), white chest, long neck and beak with most of the actual head missing. I’ve dragged a couple of pics off the net, none match but have similarities.
