BRITISH WARBLERS 



light yellow and the under part of the tail light greyish brown. 

 The iris is brown, the upper mandible light horn brown, and 

 the lower buffish flesh colour. The feet are bluish grey. The 

 sexes are alike in plumage. In autumn all the colours are 

 purer, but the upper parts are rather more brown. 



GEOGRAPHICAL DISTRIBUTION. 



This bird is an accidental visitor to the British Islands, 

 the records coming principally from the eastern counties of 

 England and from Fair Isle. That it appears here so seldom 

 is the more curious since it breeds commonly on the 

 Continent. 



It is found in north-eastern France as well as in the 

 central and southern parts. To Belgium, Holland, and 

 throughout the greater part of Germany it is a common 

 summer visitor, and generally distributed in suitable localities 

 in Switzerland. Its range extends as far as the Arctic circle 

 in Norway, and it breeds sparingly in Sweden up to Werm- 

 land. In Hungary it is seldom seen in summer, though it 

 breeds in suitable localities in Italy. Eastwards it appears 

 to be fairly common in Dalmatia, Montenegro and Bulgaria, 

 but not common in Greece. Whilst rare in Finland— it occurs 

 as far north as Kuopio — it is evidently a common breeding- 

 species in Poland, the Baltic Provinces, and Central Russia. 

 Its range in the East extends to the Orenburg region, and it 

 has occurred in the Kirghij Steppes. In the southern parts 

 of Russia it is less common, and the records from the Crimea 

 and the Caucasus are few. It winters in tropical Africa. 



LIFE HISTORY. 



I have had no opportunity of really studying this bird, and 

 can therefore only suggest to those more fortunately placed 

 that there seems to be here a fruitful field for investigation. 

 Is its behaviour response similar to that of either the Willow 

 Warbler, Chiff-chaff, or Wood Warbler, and, if not, in what
