mystery at the lime kilns?

A gentle mix of those coming and going; Larks, Pipits, Linnets, Wagtails plus single Swallow, Wheatear and Blackcap and 6 species of wader. I was aware of Ian Harrison's note of a warbler at the lime kilns on the 3rd. I listened to a bird making a repeated "seeep" call right in front of me and a very small warbler flew out. It didn't sound like a Goldcrest to me but after subsequent searching I heard a Goldcrest calling 10 minutes later so couldn't say whether it was the same bird or not. I'm not familiar with Yellow-browed warbler but someone who is may be able to tease it out from all the other calls if one is there. Whilst hanging around I counted six Robins singing in this tiny clump of bushes.
