LBJ id please

There looks to be a reddish cap on the bird so I was thinking of a Lesser Redpole, but the beak seems way to dark.

Thanks everyone - there were other (male) reed buntings about so I think that the most likely

Huh, interesting, I'd have guessed it was a male reed bunting in its winter plumage because of the colour/lack of eye stripe! You learn every day on here.

Unless my eyes are failing me, which is quite possible, there are actually 2 reed buntings in that picture - a female top left and another one, which I thought was male but stand corrected on, right.

Phew, I was starting to wonder whether I was seeing double there, Alan! :)
