Yellow-rumped Warbler

The Yellow-rumped Warbler is one of the most widespread and well-known warblers in North America. Birders affectionately refer to this species as “butter-butt,” since its bright yellow rump is an eye-catching and diagnostic field mark throughout the year. Adults also have a yellow crown patch, most obvious in adult males. This bird’s species name, coronata, means crowned. https://abcbirds.org/bird/yellow-rumped-warbler/
