The Kentucky Warbler (Geothlypis formosa) is a small, vibrant songbird with olive-green upperparts and bright yellow underparts. Notable for its striking black cap and sideburns, it inhabits dense, moist deciduous forests across the southeastern United States. Known for its elusive nature, it forages on the forest floor for insects and spiders.

Geothlypis formosa, commonly known as the Kentucky Warbler, is native to North America. Its geographical distribution primarily includes the southeastern United States, extending from southern Pennsylvania and Illinois, south to Texas and Florida, and west to eastern Kansas and Oklahoma. During migration, it can also be found in Central America, extending into parts of northern South America.

The Kentucky Warbler typically inhabits deciduous and mixed forests with dense understory vegetation. It prefers humid, lowland forests, often near streams or swamps. The species thrives in areas with ample leaf litter and dense, shrubby understory, which provide ideal conditions for foraging and nesting.

As an insectivorous ground-dweller, the Kentucky Warbler plays a role in controlling insect populations within its habitat. It forages on or near the ground, using its sharp eyesight and quick movements to capture insects and other invertebrates. The species is also an important part of the forest ecosystem, contributing to seed dispersal and the overall health of the forest floor through its foraging activities.
