THE DUSKY WARBLER IN ORKNEY. 



A New British Bird. 



Mr. W. Eagle Clarke writes to the Scottish Naturalist 

 (1913, pp. 271-3) that during the past autumn he and 

 Dr. C. B. Ticehurst with George Stout were observing 

 migration on Auskerry (Orkneys), and that on Octo- 

 ber 3rd, 1913, a strange warbler was detected and 

 eventually secured. This proved to be a female example 

 of the Dusky Warbler {Phylloscopus fuscatus) which 

 breeds in Siberia and winters in India, China, and Japan. 

 This far-eastern species is certainly a remarkable addition 

 to the British List, and it does not appear to have been 

 taken before in Europe, though Gatke thought he saw 

 one on Hehgoland on October 24th, 1876. 



We give below a full description of this new British 

 warbler, and also some notes regarding its habits which 

 have been kindly contributed by Mr. E. C. Stuart Baker.
