Ramsey Sound - Ring Ouzel - an early spring migrant or what?

This morning, as we headed to our Sound watch-point, we flushed a very handsome adult male ring ouzel from the coast path just to the north of the lifeboat station. It shot off at high speed uttering a characteristic tacking alarm call, briefly displaying its white breast-band and silvery edges to wing feathers, before disappearing behind the lifeboat station somewhere. A search with a camera a few hours later failed to relocate it.

Question is an over-wintering bird or one already heading back north from wintering grounds (e.g in Morocco perhaps?). I do recall them sometimes turning up quite early in March at upland breeding sites I surveyed for the old Nature Conservancy Council in mid Wales back in the late 1970s, but certainly not this early as far as I can recall. Perhaps it is overwintering in the general area - watch out for it, you never know!

In the Sound, more bh gulls and kittiwakes today, including at least three kitts showing oil-stains on their underparts - one adult was quite badly oiled. Has their been a leak of something near their overnight roost site? Where is their roost site anyway? Or has a small patch of something nasty passed close to Ramsey recently?

Also present were 4 ad and one first winter med gulls, a few common gulls and still one little gull present. A single common scoter heading north through the Sound being the only other bird of note today.
