Setophaga coronata coronata
A small songbird. Females are brown above, streaked body, yellow flank patches. As a Myrtle warbler it is distinguished from Audubon's warbler by its white eye ring and throat.
Spotted on thick underbrush at a Park in Pensacola, Florida.
These birds are insectivorous, but will readily take wax-myrtle berries in winter, a habit which gives the species its name. Experienced birders recognize myrtle warblers with the naked eye by their flycatcher-like habit of making short flights from their perch in search of bugs. They form small flocks on migration or in winter.
