I see from the RBA map that a Savi's Warbler and/or a River Warbler have been reported from the Fen this afternoon: I'll be intrigued to hear which - if either - it turns out to be. I've heard lots of the former and two of the latter: to me their calls are totally different, so perhaps the bird(s) have been seen rather than heard.
The following photos include two that I bought back in the days when photographers sold glossy prints at twitches: I think one is by Robin Chittenden: maybe both. Neither have details on the back, so I do apologise if you are the copyright holder: I'll remove if you e-mail me. There's also a crummy drawing I made in my 'field book' as I watched the River Warbler in Cambridgeshire back in 1989!
