178 THE SCOTTISH NATURALIST 



The Thrush, Turdus philomelus. On 2nd January two Thrushes 

 were at the Killantringan lantern at 6 a.m. From 28th January 

 right on to 6th April there are many records from our southern 

 lanterns of Thrushes attracted by the light, and returns of breeding 

 birds are noted at inland stations. Birds sent from the lanterns 

 proved to be T. ph. clarkei, and the main body of migrants were 

 evidently our breeding birds returning to their nesting quarters, 

 though there may have been some passage migrants of the typical 

 form along with them. From 19th to 25th April Thrushes were 

 passing our stations in the Northern Isles, this being doubtless the 

 emigration of T. ph. philomelus. A Thrush was at the Killantringan 

 lantern at 2 a.m. on 6th May, and one on the Isle of May on 27th 

 June and 6th July. 



On 30th August many Thrushes were at the Little Ross lantern 

 at 1 a.m., doubtless our breeding birds leaving us, one at the Isle 

 of May on 16th September, and notes of large movements from our 

 southern stations from 24th September to 1st November ; doubtless 

 most of these were emigrant T. ph. clarkei. From 29th September 

 to 5th November we have records from our northern stations of 

 what was evidently the autumn immigration of T. ph. philomelus. 

 A fresh movement took place from i3/i4th November (when 

 " uncountable numbers " were at the Little Ross lantern) up to 

 3rd December, and is recorded from the above station, the Rhinns 

 of Islay (L.), Isle of May, Pladda (L.), and Cullen : it is difficult to 

 say to which race these records should be assigned. A weather 

 movement is reported from Cullen, Little Ross, Pladda, and the 

 Isle of May from 18th to 25th December. 



The Redwing, Turdus musicus. Throughout March and April 

 we have many notes of movement of Redwings ; at first the large 

 majority refer to our southern stations, probably passage migrants 

 arriving from further south. Later the proportion of notes from 

 the northern parts of Scotland increases, and emigration overseas 

 was the main feature of the movement. Last seen Possil Marsh 

 22nd April (2. viii. 61), Corrour on 24th, Fair Isle on 25th, and the 

 Butt of Lewis on 29th April. 



The first autumn records of Redwings come from Swona on 

 28th September, Pladda lantern on 2nd October at 8 p.m., and 

 Sule Skerry, Lerwick, and Barra Head on 4th October. Thereafter 

 the main arrival began, and a stream of Redwings is recorded right 

 up to 5th November. Records of this come from the length and 

 breadth of Scotland, and the periods of maximum movement were 

 from 19th to 23rd and 28th to 30th October. On the night of
