Range and Habitat
Kentucky Warbler: Breeds from Iowa and Indiana east to New Jersey, and south to the southeastern U.S. Spends winters in the tropics. Preferred habitats include low, moist, rich woodlands with luxuriant undergrowth.
The Kentucky Warbler was named for the state where it was discovered in 1811 by Alexander Wilson.
A major threat to their habitat in many areas is the often complete loss of understory vegetation across broad areas caused by an over-abundant White-tailed Deer population.
Breeding Bird Survey data show a statistically significant 1% per year decline between 1966-2001 across its entire U.S. range.
A group of Kentucky Warblers are collectively known as a "Derby" of warblers.
