144 THE SCOTTISH NATURALIST 
Sonc-TurusH, Zurdus philomelus.— What was evidently a 
strong arrival of our British Z. pA. clarkei is recorded from Little 
Ross and Pladda (and lanterns); and from many inland breeding 
stations from 5th February to 31st March, by which time the tale of 
our breeding birds seems to have been complete. Of course some 
of the typical or continental form, 72 ph. philomelus, may also have 
been included in this movement; one of these was noted at Noss 
Head on 8th March, and from 28th March to 6th May there are 
constant records of Thrushes on their way to their continental 
breeding quarters. 
From 31st August to 5th October we have notes from southern 
stations of autumn movements of our British race of Song-Thrush. 
On 19th September the immigration of the continental race is first 
noted at Lerwick, and constant notes come from this station and 
many others in N. and E. Scotland of arrivals from overseas up to 
5th November. Our southern stations and lanterns again note 
considerable numbers of Song-Thrushes from gth to 13th October, 
2oth and 21st October, 3rd to 21st November, and 7th December, 
but in the absence of specimens we cannot say to which race these 
belonged. 
Repwinc, Zurdus musicus.—Several were at the Little Ross 
lantern on 17th January, 1 A.M. (1. 1920, 146), and many on 2oth 
March (1. 1920, 147), two at Shillay lantern (Monachs) early on 
24th February, some at Pladda on 12th March, many at Pladda 
lantern 30/31st March, and many Shillay lantern 6/7th April. Last 
seen, Bathgate roth April, Lerwick 13th, Little Ross 15th April 
(1. 1920, 147), and Foula 1st May. With easterly winds an 
enormous arrival of Redwings took place from 29th September to 
16th October, and this is recorded from every part of Scotland, 
though chiefly from the north and east. The numbers recorded 
during this period are very large, and the movement appears to have 
been of great dimensions. From 17th October to 24th November 
there is still continuous movement reported from all over the 
country, but the numbers are much smaller, and a much larger 
proportion of the notes come from southern stations, pointing to 
some emigration. A Redwing was killed at the Little Ross lantern 
on 4th December. 
RING-OUZEL, Zurdus torquatus torguatus. — Ring-ouzels are 
recorded from the Little Ross lantern on 20/2tst March, 22nd 
March, and 8th to 13th April (1. 1920, 147); from Auskerry on 
28th March, 4th, r2th (numbers) and 21st April; Shillay (Monachs) 
on 14th (L.) and r5th April (1. 1920, 93); Fair Isle on r4th-16th 
April (several) ; Noss Head on 14th; the Whalsay Skerries lantern
