igS THE SCOTTISH NATURALIST 



The first notes of arrival in autumn come from Corsemalzie, 

 where five appeared on loth October, and the Skerry vore lantern, 

 where Fieldfares arrived early on the 17th, on which day they 

 were plentiful at Cardross (Clyde). On the night of the i8th 

 they were at the Whalsay Skerries lantern, and next day they 

 are recorded from a good many localities. From 20th October 

 to 9th November very large arrivals are reported from mainland 

 and island stations alike; the records show an unusually steady 

 arrival, not the customary ebb and flow of numbers. This steadi- 

 ness of arrival was probably due to the weather conditions, the 

 constant easterly wind which blew almost without intermission 

 during this period being favourable to the passage of large 

 numbers of birds across the North Sea. Further small arrivals 

 took place up to 23rd November, a Fieldfare appeared on Pent- 

 land Skerries on 7th December, and a small flock at the Butt 

 of Lewis on 28th December, probably driven from the mainland by 

 frost. 



The Missel-thrush, Turdus viscivorus viscivoriis. — Single 

 birds are recorded at the lanterns of Little Ross and the Isle 

 of May on 3rd February, several were at the latter station on 22 nd 

 February, and at the lantern of the former station on 25th and 

 28th February. On 6th March a Missel-thrush visited the Bass, 

 one is recorded from Eoligarry on i8th March, two from Pentland 

 Skerries on 27th, and one from the Isle of May lantern on the 

 29/3oth March. By 17th June a flock of twenty-four were seen 

 at Glenling, Mochrum, and there are other notes of flocking up 

 till 27th August, when an assembly of about a hundred were 

 observed at Corsemalzie. 



A Missel-thrush is reported from the Isle of May on 20th 

 August, six at Killantringan at 6 a.m. on 27th September, four 

 at Pentland Skerries on 21st October and two there next day. 



The Thrush, Turdus philomehis. — From 3rd February to 20th 

 March there are many records of the return of Thrushes to their 

 inland breeding places, and also frequent notes, sometimes of 

 large numbers, at our southern lanterns. These probably all refer 

 to the return of our breeding birds, Turdus phihwielus ciarkei, from 

 their winter quarters. From 22nd February onwards there are a 

 few notes of Thrushes from our Northern Isles ; these strengthen 

 after 24th March and the main movement seems to have been on 

 26th March, but a few are recorded up to 19th April ; these notes 

 probably refer to the emigration of the continental Turdus
