HabitatPrimarily closed-canopy coniferous, mixed, or deciduous forest with a shaded, dense understory; also uses streamside thickets and young woodland. During migration it occupies varied wooded habitats with dense cover, while nonbreeding habitat includes tropical forest and forest edges.
BehaviorShy but vocal; forages in foliage and on the forest floor with short or springy hops, gleaning arthropods and sometimes lunging, hovering, or flycatching. Also eats fruit, especially during migration and the nonbreeding season, and migrates mainly at night.
