HabitatPrimarily coniferous and mixed forests, with some populations using deciduous forest or coastal cypress swamps. During migration it occupies varied woodland and edges; winter habitat is chiefly the canopy of mature forest, with occasional use of secondary growth.
BehaviorActive, agile foliage gleaner that searches leaves, twigs, and branch tips for insects, frequently hovering beneath leaves and occasionally catching prey in flight. It often forages high in trees and may join mixed-species flocks outside the breeding season.
