Setophaga fusca, commonly known as the Blackburnian Warbler, is a small songbird native to North America. It is notable for its striking plumage, with bright orange throat and face, contrasting with black and white patterns. This warbler inhabits coniferous and mixed forests, particularly during breeding season. It is known for its melodious song and acrobatic foraging behavior, often seen gleaning insects from foliage.

Setophaga fusca, commonly known as the Black-throated Green Warbler, is native to North America. Its geographical distribution includes eastern and central Canada, particularly in provinces like Quebec, Ontario, and the Maritime Provinces. In the United States, it is found in the northeastern and north-central regions, extending into parts of the Appalachian Mountains.

The Black-throated Green Warbler primarily inhabits boreal and mixed deciduous-coniferous forests. It favors areas with dense foliage, particularly in mature forests with a significant presence of coniferous trees such as spruces and firs. The species is adapted to regions with cool, moist climates typical of northern forests.

Setophaga fusca occupies the ecological niche of an insectivore, feeding primarily on insects and spiders found in the foliage of trees. It plays a role in controlling insect populations within its habitat. During the breeding season, it is often found in the upper canopy, where it builds its nest and forages. Seasonal migrations lead it to wintering grounds in Central America and the Caribbean, where it adapts to different forest types, including tropical and subtropical habitats.
