The Arctic Warbler

Arctic Warbler

The Arctic Warbler (Phylloscopus borealis) is widespread in the birch forest or mixed forest with birch near the water in Fennoscandia and northern Asia. The bird has also established itself in North America, where they breed in Alaska. The Arctic Warbler is a migratory bird and the entire population winters in Southeast Asia.
 The birds nest is built of moss and straw and is placed on the ground in a low bush. 
Like most warblers the Arctic Warbler mainly eats insects.
