Note. Bird was dark brown on back/wings, slightly lighter brown on underside, save for lighter head and bands on wings. Photos taken after it had circled up on thermals, but when it first circled over the campsite at double tree-top height, I would have placed the wingspan at between 2-2.5m. Also, the tail had the classic diamond/wedge shape, which is a little blurred in my photos. My apologies for not putting in this detail when I got back from camp and uploaded the photos.
