Description: 5-6" breeding male dull-bluish above streaked with black, breast and back blackish, rump, crown and small area at sides of breast yellow, variations in east-west, females, young, and fall males streaked gray-brown and always have yellow on rump and white spots on tail	Habitat: Open coniferous forests or mixed woodlands, forest edges, clearings, spruce bogs, thickets. Previously two separate species: Myrtle Warbler of the east (white throat) and Audubon's Warbler of the west (yellow throat).
Nesting: 4-5 white eggs spotted and blotched with brown, in a bulky nest of twigs, rootlets and grass lined with hair and feathers and placed in a conifer	Range: breeds from Alaska, Canada to Mexico in west, east to New York, Maine, winters from southern part of breeding range to tropics
Voice: a thin buzzy warble, and a sharp chek	Diet: Tends to be more insectivorous in west than in east; berries of shrubs, especially in winter.

Notes: very common, one of the most generalized and opportunistic of all our insectivorous birds. Gregarious, often associates in flocks, males tend to forage higher than females, may skim swallow-like over water eating insects from surface, one of last warblers to migrate, most abundant wood warbler in Canada, occasionally roost communally in winter, until recently, e and w populations were considered separate species, Myrtle (e) and Audubon's (w) Warblers.

When present in Oklahoma: present state-wide intermittently during summer and winter migrations
