During migration also forages higher in the canopy with other warblers. The female sits on the eggs for about two weeks before the eggs hatch. Sometimes flashes its tail, exposing white spots, similar to the behavior of an American Redstart. Bathes by dipping its bill in the water and tossing water over its back.

The magnolia warbler is found in the northern parts of some Midwestern states and the very northeastern parts of the US, with states such as Minnesota and Wisconsin comprising its southernmost boundaries. The magnolia warbler is assessed on the IUCN Red List as least concern for conservation because it is fairly widespread and common within its habitat and not at risk of extinction. The genus name Setophaga is from Ancient Greek ses, "moth", and phagos, "eating", and the specific magnolia refers to the type locality. White undertail coverts and black-tipped tail are diagnostic at all ages. The magnolia warbler undergoes multiple molts during its lifetime.
