254 STUDIES IN BIRD-MIGRATION 



We were gratified to find two of the lightkeepers, 

 Messrs Begg and Anderson, keenly interested in our 

 researches, and since our departure they have furnished 

 excellent records, in many cases accompanied by birds 

 killed at the lantern. On Mr Begg's leaving the station, 

 Mr Anderson has continued the observations down to 

 19 1 o. Both. these observers have earned our gratitude 

 for their very valuable contributions. The total known 

 avifauna now stands at 115 species- — a very remarkable 

 figure, but there are, doubtless, additions to come, for, 

 so far, every year has added its quota. 



The following are the species which came under 

 notice during our residence on the island : — 



Raven, Corvus corax. — A pair is resident among the 

 islands, remaining all the year round, and nesting on 

 one of the outer group. During our visit this couple 

 was seen daily, but they had evidently dismissed their 

 young before we arrived. One day a strange pair 

 appeared, to the evident concern of the titular pro- 

 prietors, who were very unsettled and noisy during the 

 trespass upon their domain. 



Grey Crow, Corvus comix. — A pair seen occasion- 

 ally at all seasons, but said not to breed ; at any rate 

 their young have not been observed. These birds were 

 seen throughout our visit, and one of them was shot, 

 but the survivor had a fresh mate two days later. 



Snow- Bunting, Plectrophenax nivalis. — A winter 

 visitor in numbers. The earliest record of its appearance 

 came under our notice, two being seen on 14th September 

 1904. A few usually arrive later in the month, but the 

 great flights do not appear until October, when they are 

 sometimes noted as in ''thousands." A considerable
