THE BIRDS OF FAIR ISLE 75 



and Chaffinches ; single examples of the Woodcock, Jack 

 Snipe, and Mistle Thrush were found dead near the tower. 

 The death-roll at the North Lighthouse is believed to have 

 been equally great, but no attempt was made there to count 

 or estimate the number of the slain. 



It is again my pleasant duty to express to the Com- 

 missioners of Northern Lighthouses my gratitude for, and 

 appreciation of, the privileges they so kindly granted to 

 Mr. Donaldson and myself ; and to Mr. Dick Peddie for 

 his valued co-operation and advice. Acknowledgments 

 are also due to Mr. and Mrs. Wallace for their great kind- 

 ness and attention to us during our residence at the Skaddan 

 Lighthouse ; and to all our good friends among the inhabitants 

 of Fair Isle, who most obligingly permitted us to wander at 

 will over their crofts in search of the feathered travellers 

 sheltering therein. 



In the following list, the species which are numbered 

 are additions to those included in my previous contributions, 

 and also to the avifauna of the island. 



Specimens of the more interesting species about to be 

 mentioned have been presented to the collection of British 

 birds in the Royal Scottish Museum. 



144. Carrion Crow, Corviis corone. — A Carrion Crow was seen 

 continually by us, and we were told that it had been on the 

 island for some weeks previous to our arrival. It always 

 associated with the Grey Crows. This species is one of 

 the additions to the Fair Isle avifauna, and has only been 

 observed as an occasional visitor to both the Orkney and 

 Shetland groups. 



Grey Crow, Corvus comix. — An example showing a tendency 

 towards albinism was shot on 20th September. This 

 specimen had several of the primaries in each wing, the 

 chin, right nasal plumes, claws, and soles of the feet white. 

 The bill was tipped with white, and the mandible was 

 white at the base. The grey portions of its plumage were 

 paler than usual and were slightly tinged with buff. 



Jackdaw, Corvus monedula. — This species had only once 

 before come under our notice, a pair having been seen on 

 8th September 1905. In 1907 many arrived on 15th 

 April, a few appeared late in October, and a single bird was 

 observed in November.
