A large flock of mainly Griffon Vultures covering a large arc of the horizon, just a few came close to the hilltop, including what I think are a Buzzard and Short-toed Eagle without bars on the tail (is it a young one?). The Griffon Vultures were over the main road from Sagres to V do Bisbo (about half way) while on the way to lunch. There was talk amongst other observers that a Ruppells Vulture was amongst this flock so I zoomed out to get more birds in the frame and cropped out these 3 birds, one of which is much darker than any of the others in the full frame, so might it be the Ruppells? I have loads more pics to go through on a bigger screen when I get home. Also have good pics of a lone Griffon sitting on a pylon beside the road near the same spot.
