PALLAS'S WILLOW-WARBLER. 

 Phylloscopus proregulus (Pallas). 

 Plate 6. 



One example of this rare Warbler was recorded by the late T. Southwell 

 {Zoologist, 1896) as having been shot at Cley-next-the-Sea on October 31, 1896. 



Pallas's Willow- Warbler spends the summer in east Siberia, where it breeds, 

 migrating for the winter to southern China and India. 



One specimen has been obtained and another seen on Heligoland. 



According to Mr. Dresser {Manual of Palcearctic Birds, p. 105): "Its nest is 

 placed on the branch of a tree near the stem, is oven-shaped, constructed of grass- 

 bents and moss and lined with feathers and horse or cattle hair, and its eggs 

 which are deposited in May or June are white dotted and spotted with violet, ash- 

 grey, and red, the spots being frequently collected round the larger end." 



It has a loud and melodious song, and frequents wooded districts.
