About These Birds
Arctic Warbler
The Arctic Warbler is a small migratory leaf warbler weighing about 11 grams with a wingspan near 13 cm, breeding across the boreal forests of Eurasia and western Alaska. It undertakes one of the longest migrations of any Old World warbler, wintering in Southeast Asia and the Philippines. Its pale supercilium and olive-green plumage are typical of Phylloscopus warblers in forested habitats.
Black-capped Woodland-warbler
The Black-capped Woodland-warbler is a small, active leaf warbler of montane forests in Cameroon, Nigeria, and adjacent Central Africa, with a distinctive black cap and white supercilium contrasting with olive-green upperparts. It inhabits the undergrowth and mid-story of highland forests above 1,200 meters. It feeds on small insects and spiders, constantly flitting through dense foliage.
