Setophaga castanea

Family: (Parulidae) Wood-Warblers

Preferred Habitat: Woodlands.

Seasonal Occurrence: Common in spring; uncommon in fall.

Song: High, thin weesa, weesa, weesa.

Notes by Susan Billetdeaux: The male Bay-breasted Warbler has a black face with chestnut throat and side plumage. Females, fall adults, and immatures are much duller and lack strong color patterns. Both sexes have white wingbars. Bay-breasted Warblers tend to forage in the middle of trees. They are among the earliest warblers to migrate south in the fall. Bay-breasted Warblers breed in the northern spruce forests of Canada. Populations have been in decline over the past 20 years. Possible causes are lack of winter habitat and spraying to reduce caterpilllars, particularly the bud spruce worm in Canada

Comments by Don Verser: In the fall, birds look very different than they do in the spring. The bay color on sides may be very reduced and the upperparts are greenish.
