Black-throated Green Warblers breed throughout Canada’s boreal forests and northeastern United States but migrate south during winter months from southern Mexico down through Central America as far as Panama.
These warblers prefer mature deciduous or mixed woodlands for nesting, where they build their nests on tree branches using twigs, grasses, bark strips, mosses, spider webs, lichens and feathers held together by spider silk.
Their diet consists mainly of insects such as caterpillars, beetles spiders aphids leafhoppers among others; they are also known to eat fruit occasionally especially during migration when natural food sources may be scarce.
