According to AllAboutBirds.com, they place their nests in low cavities such as old Downy Woodpecker holes. Bald cypress, willows, and sweet gum are regular trees used for nesting and cavities tend to be in trees located near or over standing water. These warblers sometimes use bird boxes, gourds, and cypress knees for nesting.
