Also known as Butterbutt, Myrtle Warbler, Audubon's Warbler
Yellow-rumped Warblers are among the hardiest songbirds in North America, uniquely capable of digesting the waxy coatings of bayberry and wax myrtle berries during cold winter months. Easily recognized by the vibrant yellow patches on their rump, sides, and crown, these energetic foragers flit tirelessly through forest canopy and coastal scrub alike. During spring and autumn migration, massive flocks gather along coastlines and forest edges, filling the air with sharp, metallic contact calls.
