Body mass in adult birds can range from 6.6 to 12.6 g (0.23 to 0.44 oz), although weights have reportedly ranged as much as 15 g (0.53 oz) prior to migration.

Among standard measurements, the wing chord is 5.4 to 6.4 cm (2.1 to 2.5 in), the tail is 4.6 to 5.2 cm (1.8 to 2.0 in), the bill is 0.8 to 1 cm (0.31 to 0.39 in), and the tarsus is 1.7 to 1.85 cm (0.67 to 0.73 in).

Often forages low within the understory, choosing bugs from the undersides of leaves. During migration additionally forages higher within the cover with different warblers. Sometimes flashes its tail, exposing white spots, much like the behavior of an American Redstart.

Magnolia Warbler Life cycle

The magnolia warbler undergoes a number of molts throughout its lifetime. The first molts start whereas the younger offspring are nonetheless residing within the nest, whereas the remainder happens on or close to their breeding grounds.

The warblers molt, breed, care for his or her offspring, after which migrate. Chicks hatch after a two-week incubation interval and might fledge from the nest after shut to a different two weeks when their feathers are more developed.
