Went up to Marston Vale CP to look for the Siberian Chiffchaff's there. I waited for the rain to ease then got there as it stopped, heading straight for the sewage treatment site. There were quite a few vocal Chiffchaffs present but eventually I found the Sibe's. One was a real grey bird with vibrant green wings and clean underparts, it was associating with a Chiffchaff fairly closely and so gave good comparisons. The other Sibe was more browner with less green markings. I was hand holding a smaller lens outfit due to a bad back hence the quality, the greyer bird was the one that Steve Blain had found originally, but had proved to be some what elusive since, so I was glad to of recorded the bird at least.
