BLUE-BREASTED WARBLER. 
Sylvia suecica. 
This beautiful warbler is a regular summer visitor on tlie 
Continent of Europe, where it is found in some parts in 
tolerable abundance. It arrives from Africa early in spring, 
and, spreading over the European continent, penetrates as 
far as the north of Russia, Finland, Lapland, and Sweden. 
It is also abundant in Italy, and in the mountainous districts 
of France. But the western coast of Europe appears less 
frequented by this species than other parts, since it is not 
common in the western parts of France, nor in Holland, and 
it is said not to be met with in Denmark. The fact of this 
species being more or less scarce upon the Avestern coast of 
Europe, may account for the extreme rarity of its appearance 
here, where only two specimens are recorded to have been 
taken. 
Although widely dispersed in Europe, this bird appears to 
be rather locally disposed. By Bechstein it is spoken of as 
being seen in great numbers in its spring and autumn passage 
through Thuringia ; but very few remain there to breed ; 
while in other parts of Europe, both north and south of this 
latitude, they are known to rear their young. According to 
this naturalist, the migration of the Blue-breasted Warbler is 
performed in large flights. They pursue their course along
