Hippolais sp. at Lands End (1 Viewer)

I see from Rare Bird Alert that for the last two days there has been a very elusive Hippolais sp. around Swingates at Land's End. Are there any theories knocking around the grapevine as to what it might be? Statistically, Melodious is the most likely to turn up down here in August, but I'm thinking that if it were a clear choice between that and Icterine the pagers would probably be saying so.

Ever hopeful...

Melodious are of course 10x as elusive as Icky's so that's additional circumstantial evdence! Wasn't there a Booted at Hartlepool in the week?
