Fog!

And that was nearly the only entry in my notebook for yesterday! When Kim and I got to the Obs just before first light it was misty at most and there were a number of Redwings calling overhead, by the time we had put the nets up a dense fog rolled in and it didn't shift.

We strung it out for a couple of hours and the fog was so bad that I was amazed that we actually ringed six birds as follows (recaptures in brackets):

Blackbird - 1
Goldfinch - 3
Greenfinch - 1
Sparrowhawk - 1 imm. fem.
Blue Tit - (1)

 Goldfinch

 Sparrowhawk

We only had one Barn Owl this morning that loomed out of the fog like some ghostly apparition and then it dissolved back in to the murk! As you would expect there was absolutely no vis, in fact there was virtually no birds at all. We could hear Pink-footed Geese going over and about fifteen Fieldfares appeared out of the gloom and then vanished again! And that was it!
