How do warblers live?

Warblers are small, insectivorous birds found in a variety of habitats, including woodlands, grasslands, and wetlands across North America, Europe, and Asia. They are migratory, often traveling long distances between their breeding and wintering grounds. Warblers feed primarily on insects, including beetles, flies, and moths, and sometimes berries or seeds. They are highly active, flitting through vegetation in search of food, and often sing complex songs to defend their territory or attract mates. Warblers reproduce once a year, with females building nests in trees or shrubs. They lay 3-6 eggs, and both parents help care for the chicks until they can fledge.
