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.
North America is home to two migratory Yellow-rumped Warbler groups that are sometimes considered separate species: the “Myrtle” Warbler of eastern and far-northwestern North America and the “Audubon’s” Warbler of the West. The two groups hybridize where their ranges meet in southwestern Canada, and were combined into a single species in 1973, named the Yellow-rumped Warbler.
