Physical characteristics: The Arctic warbler is 4.1 to 5.1 inches long (10.4 to 13 centimeters) and weighs 0.3 to 0.5 ounces (8 to 15 grams). It has an olive-green back, yellowish white belly, a dark eye line, and straw-colored legs. Its wings are long with two white bars on them.


Geographic range: This species is found in Alaska, Scandinavia, Japan, and the northern regions of Europe and Asia. It winters in Southeast Asia.


Habitat: Arctic warblers live mainly in deciduous forests in the North and in taiga, or subarctic wet evergreen forests. They will winter in rainforest, gardens, woodlands, and mangroves.


Diet: These birds eat insects, especially mosquitoes, and larvae.


Behavior and reproduction: The Arctic warbler finds insects and larvae in leaves, high above the ground. A very active bird, it darts among trees and will flick its wings and tail when it perches.

These birds prefer to live alone or with a mate. Sometimes, they will gather in small family groups. The male will defend his territory through song and wing twitching displays.

Arctic warblers mate for life. The female builds a dome-shaped nest of dry grasses and hair, with a side entrance on the forest floor. The female then lays five to seven pink-speckled white eggs and incubates them for eleven to thirteen days. Hatchlings stay in the nest for thirteen to fourteen days and are fed by both parents.


Arctic warblers and people: There is no known significance to humans.


Conservation status: This species is not considered to be threatened. ∎
