The Willow-Wren makes its appearance in the southern portions 
of this country about the first week in April, and from that time 
until the middle of September it is by far the most abundant of 
the three species of small greenish-yellow Warblers which annually 
visit us. In England it is generally distributed, although somewhat 
local in Cornwall; and it is common in suitable parts of Wales.

increased of late years; but to the Outer Hebrides, Orkneys and 
Shetlands (as well as the Feroes) it appears to be only a wanderer, 
chiefly in autumn. In Ireland it is very common. Occurrences of 
this bird in winter, in the milder districts of our islands, have often 
been recorded. 
The Willow-Wren ranges nearly as far as the northern extremity of 
the Continent in summer, while southward it breeds throughout the 
greater part of Europe down to the Straits of Gibraltar, and eastward 
to the Caucasus; in Siberia to as far as the valley of the Yenesei. 
Its winter-quarters may be said to begin in the south of France, and
