The myrtle warbler (Setophaga coronata coronata) earns its name earn because it feasts on energy-rich wax myrtle berries, often found on the East coast of the USA. The myrtle can be distinguished from Audubon's warbler by its whitish eyestripe, white (not yellow) throat, and contrasting cheek patch. Formerly one of four sub-species of the yellow-dumped warbler, the myrtle is the most common in the eastern U.S. and most of Canada. It’s the most different of the four forms, with a white instead of yellow throat, a longer migration, and a distribution that stretches farther north than the other forms.
