REPORT ON SCOTTISH ORNITHOLOGY IN I915 169 



September; the movement comprised departures of our 

 summer visitors, arrival of winter visitors and some passage 

 migration, rather more Pied Flycatchers than usual being 

 recorded. The movement was slightly increased from the 

 9th to the 13th, coinciding with a brief spell of south-east 

 and south wind, and there was a good deal of Wader 

 movement from the 24th to the end of the month, but at 

 no time was there anything approaching a rush. 



October. 



Up to the 8th October* the wind was from some westerly 

 quarter, and there was steady normal migration, chiefly 

 arrivals of winter visitors. From the 8th to the 24th the 

 wind was in the south-east, with the exception of an interval 

 from the 14th to the 19th, when it was westerly. During this 

 time a big rush took place, slackening somewhat from the 

 14th to the 19th, thereby corresponding to the change of 

 wind. The species affected were chiefly winter visitors, but 

 there was also a good deal of passage migration, and some 

 uncommon visitors are recorded. Thereafter to the end 

 of the month the wind was variable, and there were 

 practically no fresh arrivals, the birds recorded being mostly 

 those lingering after the big rush. 



November. 



Up to the 17th November the wind was almost entirely 

 between north-east and north-west ; thereafter to the end of 

 the month it was very variable, and frost is recorded from 

 the 14th onwards. Constant small arrivals of winter visitors 

 are recorded up to the 14th ; after this, and up to the end of 

 the month, the frost caused movements to our shores 

 and island stations. The species affected were chiefly 

 Jackdaws, Turdinae, Robins, Curlew, Jack Snipe, Lapwings, 

 and Golden Plover, the last two being recorded in large 

 numbers from our south-western lanterns on the night of 

 the 29th,
