One occurrence. Mr. Thomas Southwell records that 

 a bird of this species was sent him for determination 

 by Mr. Pashley, of Cley-next-the-Sea, on the coast of 

 Norfolk. It had been shot on 31st October, 1896, 

 and was in perfect condition and apparently an adult 

 bird. 



According to Mr. Dresser, Pallas's Willow-Warbler 

 appears regularly on migration within the limits of the 

 Western Palaearctic Region. Its range extends also 

 from the Ural Mountains to Eastern Siberia, where it 

 breeds, and probably passes the winter in Southern 

 China and India. It has once occurred on the island 

 of Heligoland. [0. 8.]
