Managed a days birding up at Durness with Peter Stronach a couple of weeks ago. A December chiffchaff in the Balnakeil craft village was a pleasant surprise this far north and we also enjoyed the spectacle of 800+ Barnacle geese and 3 tundra beans feeding in fields near the farm. The highlight however was finding two Siberian chiffchaffs. I initially found one fly-catching near the church and after we had watched it for 20 minutes and got some decent record shots we drove back to Durness where Peter located a second bird back in the village near the garage. Both birds were very lively in the mild, sunny conditions with plenty of insect life for them to enjoy. It was noticeable how much the birds appeared to change colour and tone as they moved in and out of the strong sunlight. I wonder how long it will be before these birds become a full species in their own right?
