268 STUDIES IN BIRD-MIGRATION 



of Redpoll visited Eilean Mor in October and November 



1905, and specimens were forwarded to me. This bird 

 was very abundant at Fair Isle the same season. 



Crossbill, Loxia ctirvirostra. — A considerable 

 number visited the islands during the memorable 

 irruption of the summer of 1909. They arrived late in 

 June, remained in some numbers until the second week of 

 August, and the last was observed on 22nd September. 



Two-barred Crossbill, Loxia bifasciata. — An adult 

 male was shot on 21st July from among the common 

 Crossbills which frequented the island during the summer 

 of 1909. In 1 9 10 a male was captured on 14th August. 



Yellow Bunting, Emberiza citrinella. — There are 

 three records for the occurrence of this species : one on 

 17th September 1900; twelve on 30th October 1905; 

 and ten on 12th November 1905. 



Reed- Bunting, Emberiza schcEniclus. — There is a 

 single record only — namely, of a female on 19th May 



1906, which was sent for identification. 



Lapland Bunting, Calcarizis lapponictts. — Since 

 our discovery of this species, Eilean Mor has been 

 visited annually. The dates of the appearances of these 

 supposed rare visitors are interesting on account of their 

 earliness and regularity — namely, from 3rd to nth 

 September. Specimens as vouchers have been sent. 



Snow- Bunting, Plectrophenax nivalis. — Appears at 

 the islands on passage in the spring and autumn, and 

 also as a winter visitor. 



Many are observed in spring from mid-March and 

 during April, fewer in May, down to the 19th. The 

 latest date for spring stragglers of the rearguard is 

 4th June. 



The earliest record for autumn is for 3rd September.
