Definition of Audubon's 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.
