• White spots in tail

• Winters farther north than other warblers

• Eastern (formerly called "myrtle warbler") and western forms (former-           ly called "Audubon's warbler") were previously separate species

Adult male-eastern (myrtle warbler):

• Black mask

• White supercilium and broken eye ring

• small, yellow, crown patch

• Blue-gray crown, nape, back and wing coverts with black streaks

• White throat

Similar species:

The male yellow-rumped warbler is quite distinctive with its yellow
patches at the sides of the breast and black upper breast. Magnolia
warblers have yellow bellies. Females and immatures are less colorful
and more difficult to identify. The often obvious yellow rump is brighter
than other species with yellow rumps (magnolia, palm, and Cape May).
When present, the yellow patches at the sides of the breast are not found
in these other species. Cape May warbler has finer and more extensive
streaking on the breast and a yellow neck patch. Palm warbler has
yellow undertail coverts and actively pumps its tail. Magnolia warblers
have much more yellow below.
