Arctic Warbler
Phylloscopus borealis
Leaf-Warblers
At a Glance
Along willow-lined streams in Alaska in summer, the song of the Arctic Warbler is unmistakable: a slow trill, with an insistent or hammering sound. When the bird hops into view among the branches, it is less distinctive, plain olive and whitish with a pale eyebrow. In fall, the Arctic Warbler crosses the Bering Strait and migrates south in Asia.
