- ORDER: Passeriformes
- FAMILY: Phylloscopidae
The Arctic Warbler is a brownish olive warbler with a prominent cream-colored eyebrow. It is in the Eurasian leaf warbler family (Phylloscopidae) and unrelated to the other warbler species that occur in North America (Parulidae). Arctic Warblers forage restlessly through the leaves of trees and shrubs, searching for caterpillars. In Alaska, the species breeds in wet, shrubby areas, where its trilling song is reminiscent of species such as Orange-crowned and Wilson’s Warblers. In fall, these birds migrate across the Bering Strait to winter in Southeast Asia.More ID Info
Find This Bird
The best way to see an Arctic Warbler is to head to Alaska (or northern Eurasia) and search for singing males during June or early July. Males return to breeding grounds in early or mid-June, and the breeding season is short. They sing mostly from exposed perches in wet, shrubby areas, but can be difficult to see in dense cover. Bring mosquito repellent and netting for this habitat in summer!

- Cool Facts
- Male Arctic Warblers produce an odd rattling or buzzing noise with their wings, often between bouts of singing, when changing song perches.
- In both the Central Yupik and Inupiaq languages of Alaska, the names for Arctic Warbler include the word for gallbladder, possibly because that organ is greenish brown, like the plumage of the bird.
- The Arctic Warbler is one of the few species that breeds in North America and winters in Asia. Other such species include Pacific Golden-Plover and Northern Wheatear.
- The oldest Arctic Warbler was a banded bird at least 3 years, 1 month old when it was recaptured and re-released.
