The Arctic Warbler is a widespread leaf warbler in birch or mixed birch forest near water throughout its breeding range. It has established a foothold in North America, breeding in Alaska. This warbler is strongly migratory; the entire population winters in south east Asia. It therefore has one of the longest migrations of any Old World insectivorous bird. Leaf warblers are active, constantly moving, often flicking their wings as they glean the foliage for insects along the branches of trees and bushes. They forage at various levels within forests, from the top canopy to the understory. Most of the species are markedly territorial both in their summer and winter quarters. The nest is on the ground in a low shrub. Like most Old World warblers, this small passerine is insectivorous.
