The moth immigrant tally remained at a samey level, with 4 Rusty-dot Pearl and 3 each of Diamond-back Moth and Silver Y caught overnight at the Obs.
Also on a bird front there are a couple of other snippets of news to report:
Nick Hopper was with us again at the weekend (Saturday night/Sunday morning) undertaking another session of nocturnal sound recording. This was quite an interesting night to try the technique as the sky remained more or less clear throughout (it was starlit and with a half moon visible well into the early hours before some low mist formed for a while) and to the unassisted ear it sounded like the volume of passage overhead was fairly slight; however, Nick reports that the dish picked up totals of 219 Redwings, 19 Song Thrushes, 12 Blackbirds, 4 Fieldfares and singles of Lapwing and Dunlin in a four hour period from 21.40 to 01.40 before - maybe surprisingly - passage dwindled once the mist had set in.
Our other news concerns the Western Bonelli's Warbler trapped and ringed at the Obs back in August. Although this bird conformed in all tangible respects to a Western as opposed to an Eastern Bonelli's, during the handling process we did happen to come by a couple of feathers which we thought we may as well submit to Dr Martin Collinson at the University of Aberdeen for mtDNA analysis. Martin has very kindly been in touch as follows: 'finished the Western Bonelli's from Portland (18/8/2014, HBV514) (our ref PBo01).......confirms it's Western, of course, novel sequence but 2-3 bp different from 3 Western Bonellis, 2-5 bp difference (/932 bp) in GenBank, at least 25 bp different from any Eastern Bonelli's, and also 25 bp different from sibilatrix'.
