THE BIRDS OF FAIR ISLE 69 



generally supposed, and this is especially the case on the main- 

 land. Thus the Lapland Bunting, which was so numerous 

 at the Flannans and at Suleskerry in the autumn of 1904, 

 and at Fair Isle in 1905 and 1906, entirely escaped notice 

 elsewhere in Scotland ; and the Yellow-browed Warbler which 

 was observed at Fair Isle in 1905 and again in 1906 (when 

 it was not uncommon, and was also captured at Skerryvore), 

 has never been detected on the mainland of Scotland. On 

 reaching the mainland the migrants, especially the passerines, 

 become widely scattered over the country where cover 

 abounds, and thus the vast majority of them escape notice. 



Specimens of all the birds mentioned, or about to be men- 

 tioned, have been presented to the Royal Scottish Museum. 



It is again my pleasant duty to express our gratitude to 

 John Bruce, Esq., of Sumburgh, and to the Commissioners of 

 Northern Lighthouses, for the privileges they so graciously 

 granted us ; and to Mr. Dick Peddie for his kind and valued 

 co-operation. Our acknowledgments are also due to Mr. 

 and Mrs. Wallace for their great kindness during our residence 

 in the Skadan Lighthouse, and to our many good friends 

 amoncr the natives, who allowed us to visit their crofts, the

great resort of the small migratory birds. 



In the following list the species that are numbered are 

 additions to the one hundred recorded in my first contribu- 

 tion. Certain other birds are treated of, and concerning 

 these the information now given is supplementary to the 

 data of 1905, and throws additional light on them as Fair 

 Island species. 



CHAFFINCH, Fringilla coelebs. This migratory visitor was 

 observed in the autumn of 1906 in much greater abundance 

 than it did at same season of the previous year. They 

 arrived during the last week of September in fair numbers, 

 but were much more numerous during October, and a few 

 remained throughout the winter. It is, as we should expect, 

 a bird of double passage at Fair Isle, and was observed on 

 its spring journey northwards on several days about mid- 

 April. 



101. LINNET, Acanthis cannabina. An adult male, obtained on 

 1 8th April, is the only bird of this species which has, as yet, 

 come under observation. There is also little information 

 regarding this bird as a Shetland species.
