They feed on insects gleaned from vegetation or hawked from the air usually high in the trees. The cup-shaped nest is made of twigs and shredded bark and placed high on a horizontal branch.

Formerly the eastern white-thorated) population was considered a separate species, the Myrtle Warbler, from the western yellow-throated) Audubon\s Warbler.'
