192 THE BIRDS OF THE BRITISH ISLES. 



Yellow-browed Warbler. Phylloscoptis siipcrdUosus 

 (Gmel). 



Systematic study of migrants at the Scottish hghthouses and 

 on northern islands proves that the Yellow-browed. Warbler 

 (Plate 70) is a regular autumn visitor and bird of passage. 

 It has also occurred not infrequently on the east coast of 

 England, and occasionally in Kent, Gloucester and the Scilly 

 Islands, as well as in Ireland, and it has twice been noticed in 

 spring. Its home is Siberia, where several ornithologists have 

 referred to its song. Miss Haviland says that on the Yenesei, 

 " its little monotonous song tinkled on without ceasing from 

 every bush." Its normal winter quarters are India, Burmah 

 and south-eastern Asia, but its migratory travels appear to 

 drift westward also, for it has been met with in various parts of 

 Europe. 



Its size, simple song and double lemon-yellow wing-bars 

 rather suggest a Goldcrest, but it is a typical leaf- warbler, olive- 

 green and yellowish white ; its salient character is the long 

 yellowish eye-stripe, extending from the base of the bill to the 

 nape, with a darker line through the eye. There is a faint 

 lighter streak down the centre of the olive crown. The bill, 

 legs and irides are brown. Length, 3*8 ins. Wing, 2*15 ins. 

 Tarsus, 7 in. 



Pallas' Warbler. Phyllo scepsis proregulus (Pallas). 



This small Siberian Warbler, like the last species rather 

 suggesting the Goldcrest, winters in southern China, but has, 

 on rare occasions, strayed westward ; it has been shot on 

 Heligoland, and once, in 1896, in Norfolk. It is yellower than 

 the Yellow-browed Warbler and its superciliary stripe is lighter ; 

 there is a central yellow streak on its crown. The most
