Yellow-rumped Warbler

The Yellow-rumped Warbler, also known as "butter butt," is a vibrant, small songbird with distinctive yellow patches on the rump, sides, and crown. Found across North America, they inhabit forests, woodlands, and urban areas. These warblers can digest waxy berries like bayberries, allowing them to survive in colder climates. Their migration includes impressive long-distance travel, often in large flocks. They can change their diet seasonally, even sipping sap from tree holes left by sapsuckers.
