Cornish Choughs - Pyrrhocorax Pyrrhocorax on the cliffs just south of Mullion Cove. They disappeared from Cornwall in the mid 70s and reappeared in 2001, see http://www.rspb.org.uk/ourwork/projects/details/223656-cornwall-chough-project
This is their normal behaviour, charging about on the very steep rock faces about 100 times as fast as a photographer can (if at all). It would not be Chough portraiture to show them in one place for very long!
