Suspecting from casual observations from the seafront that there were quite a lot of Red Throated Divers around, I got down to Rock-a-Nore at first light. Even while it was still quite dark, groups of divers started moving west, their numbers increasing and reminding my of my record count of 512 in 1.75 hrs on Jan 18 2009.
However, this impressive count was quickly passed, and after 90 minutes no less than 1334 had headed west and the movement [presumably a feeding movement by the local population] seemed to stop. My attempt to leave then failed as my car wouldn’t start, and while I was waiting for the rescue service,not watching continuously, a minimum of 160 more flew west. The total of 1500 + shows just how important this area is for Red Throated Divers [in nearly 50 years birding I’ never seen anything like this], it included 3 flocks of 150 birds each. Although all these birds moved west, quite a lot stopped briefly on the sea.
There were at least 2 Black Throated Divers, 40 Gannets and 50 auks, mostly going west, also some distant large skeins of geese which were not necessarily Brents, and an Eider near the breakwater
