...the ever-compelling sight of tern passage over Chesil (and for that matter off the Bill) invariably throws up as many questions and opinions as it does answers and truths. Our two images above show part of one flock that shaved the top of the beach on their first attempt at the crossing and headed off rapidly eastwards over Ferrybridge, and part of a second flock that made several attempts hundreds of feet above us but always bottled out at the last minute. Close examination of the series of photos of these flocks show that, as is often suspected with these 'late' birds, the vast majority are Arctic Terns; more worrying however, at least from the recording point of view, is that there are several clear-cut Common Terns (as well as a few birds we're not sure of) amongst them. Bearing in mind that the vast majority of flocks can't be subjected to the photographic scrutiny that these were, it really does seem safest just to log the lot as commic terns.
