172 THE SCOTTISH NATURALIST 



from Largo on 4th May, Kilmacolm next day, and Dundee, Beith, 

 Glenorchard, Allander Toll, Knightswood, Bearsden, and Cathcart 

 on 6th May. After this there are many notes of the arrival of 

 Whitethroats at their breeding-places. Movement is reported at 

 the Little Ross lantern up to 20th May, and by 24th May our 

 nesting birds appear to have been present in force. Passage 

 migrants are recorded at Lerwick on 20th and 23rd May. 



Autumn movement was noted at Summerston by 5th August, 

 and by 19th August many had left Fife and Forfarshire. Last 

 seen at Swordale on 1st September, Beith on 5th, Bathgate on 15th, 

 and the Isle of May on 17th September. Passage migrants 

 occurred at Lerwick on 2nd September, 19th and 24th October. 



The Lesser Whitethroat, Sylvia curruca curruca. Some 

 visited the Isle of May on nth May, and one is reported from 

 Duns on 28th May and onwards (1. 191 7, 214) see p. 150. 

 Several were on the Isle of May on 27th and 28th August. 



The Fieldfare, Tardus pilaris. Small weather movements 

 are recorded from our coasts and islands in January and about 

 mid-February, evidently caused by the severe frost. From 20th 

 March to the end of April steady northward movement is noted 

 from stations all over Scotland, but nothing in the nature of a rush. 

 Last seen at Beith on 3rd May, Glenorchard on 10th and Darvel 

 on 19th May. The autumn notes on this species form an 

 instructive example of the influence of continuous westerly winds 

 on the movements of Fieldfares. They are "flocks at Dunkeld" 

 on 29th October and a Fieldfare at Lerwick on 1st November. 

 Many of our recorders comment on the absence of this and other 

 Turdinae during the autumn migration of 191 7 and the ensuing 

 winter. 



The Missel-thrush, Turdus viscivorus viscivorus. Two 

 Missel-thrushes are reported from Barra Head on 18th April, and 

 single birds visited the Isle of May on 16th March, 13th May, and 

 25th December. 



The Thrush, Turdus phi lomelus. During January and the first 

 half of February weather movements, caused by the frost, are 

 recorded from our shore and island stations. From 18th to 25th 

 February very strong movement is reported from our south coast 

 stations, and from 2nd to 23rd March in a lesser degree; these 

 were probably returns of our own T ph. clarkei. From 6th to 

 9th March a weather movement (S.E. gale, snow, and frost) is 

 noted at coast and island stations. On 1st April a Thrush visited
