ANNALS OF SCOTTISH NATURAL HISTORY 



Coasts. At Tiree, Whimbrel were seen passing north in 

 unusual numbers during the first week of May, and the 

 northern migration of the White Wagtail (M. alba] was 

 again observed. The principal movements during the 

 autumn are recorded for the first and last weeks in October, 

 On the East Coast, rushes, observed at Pentland Skerries. 

 Peterhead, and Girdleness, took place on October 7 and 8, 

 during a northerly gale, comprising Song and Missel Thrushes, 

 Blackbirds, Redwings, and Chaffinches. A second rush of 

 Turdidce was noted at Girdleness on October 30 and 3 I, with 

 heavy gales from the south ; and during the last few days of 

 December there was a general movement of Thrushes south- 

 wards along the Aberdeenshire coast, accompanied by snow 

 and gales from N.E. 



The principal rush observed on the West Coast took 

 place between October 4 and October 7, with light south- 

 easterly breezes and haze, and included Song and Missel 

 Thrushes, Blackbirds, Fieldfares, Redwings, Wheatears, some 

 Willow Wrens, and a few other birds. Other rushes, chiefly 

 of Song Thrushes and Blackbirds, occurred on October 13, 

 October 28, and November 25. These movements are 

 only recorded from Skerryvore, but the extreme paucity of 

 reports from West Coast light-stations renders this negative 

 evidence of little value. 



The closing days of the year, following the northerly 

 gale of December 22, witnessed the beginning of the great 

 irruption of Little Auks (Alergnhis alle] which characterised 

 the past winter, and has been fully treated of by Mr. W. 

 Eagle Clarke in the April number of the " Annals." 



Finally may be mentioned the interesting occurrence of 

 the Sub-Alpine Warbler (Sylvia subalpind] in the Outer 

 Hebrides ; a specimen of this bird killed on the island of 

 St. Kilda on June 1 3 by Mr. J. S. Elliott being the first 

 record of this southern species for Britain.
