Thursday 20th August
A fine day with some sunshine but a cool northerly wind.
Jim Dickson started the day off with more news of the GPS-marked Knot, which arrived at Gruinart yesterday morning, to say that it had returned to North Uist which it had visited before coming to Islay. Speculation about this unusual movement centered round it possibly wanting to return to a larger flock, but that really is just speculation. Whatever the reason, there's no doubt that large gaps in our knowledge of bird migration are being filled by the use of GPS tags. What is also of interest is that Clive McK saw Knot moving south from Gruinart yesterday evening, but clearly not including this bird.
In the late afternoon. Clive saw 4 Arctic Skuas, including a superb pale adult, heading south low over his house above the west shore of Loch Gruinart. They climbed and circled as they headed towards Bushmill, then turned west high over Carnduncan, ignoring Loch Indaal and heading to Loch Gorm/Machir Bay. Clive has seen Arctic Skuas follow this line before, and thinks that they might have come from the east coast of Scotland, following the Great Glen to the west coast on the back of the NE and N winds.
And here is a photograph by the late Gordon Langsbury of a pale phase Arctic Skua.
