The family Parulidae, commonly known as New World warblers or wood-warblers, is a diverse group of small, often brightly colored passerine birds primarily found throughout North and South America. Members of this family are generally insectivorous, feeding on insects and spiders, though some may consume berries or nectar. Parulidae species are known for their agile foraging behavior in trees and shrubs and their melodious songs, which play a key role in mating and territory defense. They exhibit a wide range of plumage patterns and seasonal coloration, with many species showing brighter colors during the breeding season. Most are migratory, traveling long distances between breeding and wintering grounds, making them important indicators of habitat health and ecosystem changes.
