REPORT ON SCOTTISH ORNITHOLOGY IN I915 187 



The Rkdwing, Turdus musicus. — On i8th February numbers 

 of Redwings were at the Little Ross lantern from 12 to 4 a.m., and 

 one is noted at Lerwick. Throughout March and up to i8th April 

 there are constant notes of movements of Redwings from all parts 

 of Scotland ; passage migrants would appear to be included in these 

 movements as well as our winter visitors, as our southern lanterns 

 and stations report immigration, and the movements reach all the 

 way up to Shetland. After i8th April the notes refer almost 

 entirely to emigration from our Northern Isles and Outer Hebrides, 

 the only exceptions being a flock of twenty-seven at Alticig on 28th 

 April and one at the Isle of May on ist May. After this, the only 

 notes are of single birds at Fair Isle on nth, 17th, and 22nd May. 

 The earliest record in autumn' is from Corsemalzie on 22nd Sep- 

 tember, a flock of about three hundred being seen flying south. On 

 29th September Redwings are reported from the Isle of May and 

 next day from Pentland Skerries and Longcroft, while on ist 

 October there were several on Fair Isle and numbers at the Little 

 Ross lantern at midnight. From 2nd October to 19th November a 

 steady stream of Redwings is recorded ; up to 24th October this 

 comprised immense numbers of birds, and it is recorded from 

 stations all over Scotland, though chiefly from our Northern Isles. 

 After 24th October the numbers recorded are smaller, though the 

 arrivals continued very constantly. Up to loth December a few are 

 recorded fairly frequently from Pentland Skerries and Fair Isle, and 

 a Redwing was killed at the Killantringan lantern on 14th December. 



The Ring-ouzel, Turdus torquatiis torquatus. — Is first recorded 

 from Braidshawrigg on loth April, Longcroft on 15th, and Kinnel- 

 head on 20th April. One or two Ring-ouzels are noted at the Isle 

 of May on 30th April, ist May, and 6th to 9th May, probably 

 passage migrants, while a female on the Island of Noss on i8th May 

 doubtless belonged to this category. On 4th October at 3 a.m. and 

 on 9th October at 10 p.m. single birds were at the Killantringan 

 lantern and at the Isle of May on 9th and loth October. Passage 

 migrants are noted at Swona on nth and 14th and from 20th to 

 26th October, at Sule Skerry on i6th October, at the Butt of Lewis 

 lantern early on 19th October, and at Pentland Skerries on 22 nd 

 October. 



The Blackbird, Turdus vierula meruIa.— On i8th January 

 four Blackbirds arrived on Sule Skerry, and many were killed at the 

 Little Ross lantern and one at the Killantringan lantern on 6/ 7th 

 February. From nth February to 27th March there are numbers
