I ringed just five birds as follows:
Chiffchaff - 2
Goldcrest - 2
Robin - 1
The Goldcrests and Chiffs were laden with fat and I wondered where they might have been heading before being grounded by the murk. In total I thought there were seven Goldcrests and three Chiffchaffs around. In addition to these to species other grounded birds included a Fieldfare and 55 Meadow Pipits.
One of the 'fog bound fatties', a Goldcrest
Even though it was foggy there was still some vis and birds were moving above and on the upper limits of the fog. In total I had 60 Meadow Pipits, a Collared Dove and a Linnet.
Back home in the moth trap were three Common Quakers, a Light Brown Apple Moth, three Hebrew Characters and an Early Grey.
I will try again in the morning but at 1935 as I type the fog has yet to clear!
