On the Sunday, a House Martin was feeding along the cliffs in poor weather. It being a late bird (and me being an optimist), I racked my brain for features of 'eastern' House Martin (lagopodum). All I could remember was that the shape of the rump patch was one, but this bird definitely conformed to a regular House Martin - there are some pointers on Birding Frontiers.
