Black Guillemot has long been a bogey bird of mine and arguably the 'commonest' bird I'd never seen in the county.
So, with a confiding juvenile bird having been showing most of the day off Cley Beach carpark I dashed up there this evening and the bird was present on arrival for a bit of 'easy birding'! About 30 yards offhsore it showed very well despite diving frequently. In time it drifted west a few hundred yards, probably with the tide and it was time to quit the scene. Apart from a couple of Fulmars, Sandwich Tern and small groups of Common Terns heading west towards the point it really was just a dirty twitch!
