 are two bands of lemon yellow across the coverts, and the 

 inner web of the outer tail feathers is margined with white.

PALLAS' WILLOW WARBLER 



Phylloscopus proregulus (Pallas) 



A single example of this Asiatic species has been 

 obtained in Great Britain, its true home being across 

 Eastern Siberia, where it nests from Lake Baikal to the 

 Himalayas and Northern China. It closely resembles the 

 Yellow-browed Warbler, but its colours are brighter. The 

 crown stripe is well marked. The inner web of the outer 

 tail feathers is not margined with white, but its most 

 distinctive feature is the bright lemon yellow rump 

 Length 3'7 in. ; wing 2 in.

Phylloscopus viridanus, Blyth 



In summer this species inhabits Western Siberia from
