Kittiwakes at Splash Point

There were a few Kittiwakes, both on the cliff-face nest sites and circling around, when we arrived at about 11:00am, but many more had turned up when we passed by again at about 14:00.  They were all over the cliffs and circling excitedly in front of it and there was a flock of about 50 birds on the sea.  I guess there were at least 150 birds in the area, and possibly many more.  This seems very early.  They are normally expected in mid March, so this is about a month early.  Large flocks are reported along the coast in January and February in some years, but I cannot find a record of a lot of birds on the breeding area at this time.   The video gives you an impression of the noise and excitement of this first arrival, even if you cannot see the individual birds.
