Despite largely clear skies overnight it remained quite mild and there was a decent arrival of immigrant moths at the Obs; a Red-headed Chestnut was the highlight, with 13 White-speck, 3 Radford's Flame Shoulder and an Olive-tree Pearl amongst the rest of the catch.
The Dusky Warbler proved to be a frustrating bird: when first discovered it was very vocal and easy to follow even if it afforded little more than glimpses and flight views - it had all the feel of something that had just dropped in; however, it quickly became all but silent and before long vanished into thin air just as we thought we had it pinned down in an isolated clump of Tree Mallows - all we were left with to remember it by was a dodgy phone-recording:
