The bird is known for its distinct yellow underbelly, black mask, and olive-green back. The Kentucky Warbler is a migratory bird that travels from its breeding grounds in the eastern United States to its wintering grounds in Central America and northern South America.
Physical Characteristics of the Kentucky Warbler
The Kentucky Warbler is a small bird, measuring about 13 cm in length and weighing around 12 g. It has a bright yellow underbelly and black mask that extends from its eyes down to its throat.

The male and female birds are similar in appearance, but the female is slightly duller in color.
Habitat and Distribution of the Kentucky Warbler
The Kentucky Warbler is found in the eastern United States, from southern Michigan to the Gulf Coast and from the Atlantic Ocean to the Mississippi River. It prefers to live in deciduous forests, especially those with thick undergrowth and a dense canopy. The bird is also found in swamps, riparian areas, and brushy fields. During migration, the Kentucky Warbler can be found in a variety of habitats, including scrublands, mangroves, and coffee plantations.
Diet and Feeding Habits of the Kentucky Warbler
The Kentucky Warbler is an insectivore, feeding on insects and other arthropods. Its diet includes caterpillars, beetles, spiders, and flies. The bird forages on the ground or in low vegetation, using its bill to probe for insects. It also gleans insects from leaves and branches. The Kentucky Warbler may also eat fruit, especially during migration.
Reproduction and Breeding Behavior of the Kentucky Warbler
The Kentucky Warbler breeds from late April to early August. The male establishes a territory and sings to attract a mate. The female builds a cup-shaped nest on the ground or in a low tree or shrub. The nest is made of grasses, leaves, and other plant materials and is lined with fine materials such as hair and feathers. The female lays 3-5 eggs, which she incubates for about 12 days. The chicks fledge after about 10 days and are cared for by both parents.

Migration Patterns of the Kentucky Warbler
The Kentucky Warbler is a neotropical migrant, meaning that it travels from its breeding grounds in North America to its wintering grounds in Central and South America. The bird migrates at night, using the stars to navigate. It typically leaves its breeding grounds in late August or early September and returns in late April or early May.
