REPORT ON SCOTTISH ORNITHOLOGY IN 1 9 1 5 191 



The Norwegian Bluethroat, Ltisciiiia suecica gaetkei. — A 

 Bluethroat, probably of this race, visited Fair Isle on 8th October. 

 See p. 151. 



The Redbreast, Erithacus ritbecula. Redbreasts, doubtless 

 the typical E. r. rubecula, wintered in Shetland ; last seen at Lerwick 

 on 29th March, and single birds were on Pentland Skerries on nth 

 and 13th April : there are no notes of large passage movements in 

 our Northern Isles this spring. The southern records this year are : 

 one at the Killantringan lantern at 3 A.iM. on i6th February, one at 

 the Isle of May on 21st March and at the Little Ross lantern at 

 3 A.M. on 24th March, two at the Killantringan lantern at 9 p.m. on 

 nth April, one at the Isle of May on 19th and several there on 

 30th April. It is difficult to know to which race to assign these 

 notes ; probably some of the later were passage migrants. 



On 1 6th August several Redbreasts were at the Little Ross 

 lantern at 2 a.m., and Little Ross (L.), Killantringan (L.), Rhinns of 

 Islay (L.), and the Isle of May record movement fairly frequently 

 between nth and 17th September and on ist and 4th October. 

 Birds sent proved to be E. r. iiielophilus, so this was evidently 

 a southward movement of our home-bred birds. A very large 

 Continental immigration is recorded from many stations in our 

 Northern Isles between 8th October and 6th November : the height 

 of the movement was from 20th to 23rd October; at this time 

 Robins were unusually numerous on the Isle of May and at 

 Tarbatness, probably also immigrants of the typical E. r. rubecula. 

 Single birds are noted at the Killantringan lantern on 13th and i6th 

 October and 2nd and 3rd November, and many at Little Ross on 

 2 ist October, but in the absence of specimens it is impossible to 

 say to which race they belonged. Large numbers visited Killan- 

 tringan on 1 8th November in frost, one was on the Bell on 

 29th November, and a few are noted from our Northern Isles 

 up to the end of the year. 



The Hedge-sparrow, Prunella modularis. — A Hedge-sparrow 

 visited the Isle of May on 21st February, and single birds, 

 probably passage migrants, are noted from Pentland Skerries on 

 loth and T2th April. 



A good deal of movement is reported from the Isle of May 

 from loth October to 23rd November, and several at Little Ross 

 on 27th October; we cannot say to which race these migrants 

 belonged.
