On average they have more white on the tail than other age/sex classes. SY females have the palest tail of any age/sex class, and with the most restricted amount of white, often just on r5 and r6 in Myrtle Warblers, but extending as far as r4 on some individuals (and on most Audubon's Warblers).

These birds are insectivorous, but will readily take wax-myrtle berries in winter, a habit which gives the species its name. AHY males have the darkest wings of all age/sex classes. In some cases the facial mask is not as black as on ASY males, and often SY males can be easily recognized by the presence of brown feathers contrasting with the otherwise blue-gray back. The uppertail coverts have narrow to moderately wide black centres, usually with some brown edging, although it may have worn off by spring. Young leave nest after 10-12 days, can fly short distances 2-3 days later.
