Geothlypis trichas, commonly known as the Common Yellowthroat, is native to North America. Its range covers much of Canada and the United States, extending into parts of Mexico and Central America. During the breeding season, it is found from southern Canada through the contiguous United States, while in winter, it migrates to the southern United States, Mexico, and Central America.

The Common Yellowthroat inhabits a variety of wetland environments, including marshes, swamps, and wet meadows. It is often found in areas with dense, low vegetation such as cattails, willows, and other shrubby or herbaceous plants. The species prefers warm and humid climates especially in its wintering grounds.

This species occupies a niche as an insectivore, feeding primarily on insects and spiders. It is well-adapted to foraging in dense vegetation where it uses its agility to glean prey from leaves and stems. The Common Yellowthroat plays an important role in controlling insect populations within its habitat.
