I think it reminded me of the golden plovers up on the Lansdown outside Bath. There is an old B/A cemetery at the far end of the downs, and if you were to go early morning in the winter months, you could find them resting in the grass, they take to the air and perform a spectacular aerial dance in the sky with a lovely plaintive cry as they swoop and turn in unison.
What with the deer browsing and foxes returning home from their nightly work, rabbits, hares and badgers, megaheads seem to forget the natural world which also inhabit the landscape of the prehistoric monuments.....
