REPORT ON SCOTTISH ORNITHOLOGY IN 1917 173 



Hellyar Holm, perhaps an example of T. ph. philomelus, on its way 

 overseas, and a Thrush was killed at Little Ross lantern at 2 a.m. 

 on 25th April. 



On 8th July great numbers of Thrushes were seen among the 

 bracken on Dumbarnie Links near Largo, probably a local move- 

 ment in search of food, induced by the drought. 



Some notes come from our southern stations from 24th September 

 to 13th October, and probably refer to departures of T. ph. clarkei, 

 while records of arrivals of Thrushes from the Isle of May, Cullen, 

 Pladda, and Swona between 29th October and 8th November may 

 refer to the Continental T ph. philomelus; the usual large 

 immigration in October and November is, this year, remarkable 

 by its absence. 



The Redwing, Turdus musicus. Redwings struck the Pladda 

 lantern on 22nd and 25th February and the Little Ross lantern 

 on the latter date, while a weather movement to the coasts is noted 

 on 8th and 9th March. Steady passage northward is recorded from 

 20th March to 22nd April from stations all over Scotland, the 

 largest numbers being at the Little Ross lantern on 18/ 19th April, 

 Galson on 21st, and the Rhinns of Islay lantern that night, and 

 Sule Skerry and Tiumpanhead on 22 nd April. Last seen North 

 Unst 26th April, and Galson 5th May. The first Redwings seen 

 in autumn were at Bathgate on 27th September, Lerwick follows on 

 1 2th October, and Dhuheartach, Sule Skerry, and South Uist next 

 day. From 17th to 22nd October, and from 29th October to 

 5th November, small immigrations took place, but there is no trace 

 in 191 7 of the enormous autumn arrivals which usually take place 

 and the species was exceedingly scarce all winter. The reason for 

 this we consider to be the same as in the case of the Fieldfare, q.v. 

 On 15th and 20th November a few Redwings struck the Pladda 

 lantern. 



The Ring-ouzel, Turdus torquatus torquatus. One is recorded 

 from Kinnelhead, Beattock, on 24th April, and early next morning 

 one was killed at the Little Ross lantern. About forty, evidently 

 passage migrants, visited Foula on 29th April, and one was on the 

 Isle of May on 13th May. On 27th August a Ring-ouzel was 

 killed at the Little Ross lantern, and one is recorded from 

 Dhuheartach on 10th December, a very interesting date. 



The Blackbird, Turdus merula merula. Up to 3rd February 

 a good deal of movement of Blackbirds is recorded from Sule 

 Skerry, Lerwick, Swona, Kyleakin, the Isle of May, Rhinns of
