Yellow-rumped Warbler

About the Yellow-rumped Warbler

The Yellow-rumped Warbler is a lively and adaptable songbird recognized by the bright yellow patch on its rump, often visible in flight. In breeding season, males show bold gray, black, white, and yellow patterns, while in winter they appear softer and more muted. Frequently seen in flocks during migration and winter, this warbler thrives in a variety of habitats.

Fun Facts

• The Butter-Butt: Birders sometimes nickname this species butter-butt because of its bright yellow rump.
• Winter Survivor: Unlike most warblers, Yellow-rumped Warblers can digest waxy berries, allowing them to stay farther north during winter.
• Two Main Forms: There are two major groups in North America — the Myrtle and the Audubons — with slight differences in appearance.
• Constant Movers: They rarely sit still for long, often flicking their wings and tail while foraging.
