Audubon's warbler

noun

variants or less commonly Audubon warbler

: a yellow-rumped warbler of a subspecies (Dendroica coronata auduboni) found in western North America and distinguished from the related myrtle warbler by its bright yellow throat patch

The birds come in two forms, the western variety, also called Audubon's warbler, and the eastern, known as the myrtle warbler, which looks a bit different but can sometimes be seen in the west.
