Fall adult: similar to spring adult, but generally browner above in both sexes with less black on breast. Spring female: similar to male, but brownish above with smaller tail spots.

Built in June on the fork of a horizontal conifer branch near the trunk at low to moderate height, the yellow-rumped Warbler’s nest contains 3 to 6 eggs. The yellow-rumped’s unique ability to digest the waxes in bayberries allows it to winter farther north than other warblers. Although variable, all yellow-rumped warblers possess a bright yellow rump, which is shared with only 2 other species.
