The fog started rolling in early Sunday evening
But as I went up to the Beacon to watch the Terns and then onto Rona to check the Greater Black-backed Gull productivity I realised the island had a very different atmosphere.
The Gulls were quieter then usual and the Terns were very inactive on my watch. A foghorn from an anchored ship could be heard to the north.
Puffins enjoyed the weather with plenty on the cliffs all day
Visibility was down to 100 metres at times
The Mainlight is not much use in these conditions
Shame the horns were not sounding
The May Princess came in through the fog.....
And left in bright sunshine
