Description
This is a small warbler, measuring 11.6 cm (4.6 in) long, weighing 8–10 g (0.28–0.35 oz), and having a wingspan range 20 cm. The male has black throat, black ear patch bordered in white, and a yellow crown and wing patch. Females appear similar to males, with a light gray throat and light gray ear patches. In both sexes, extensive white on the tail is conspicuous from below. Underparts are grayish white and the bill is long and slender. Unlike most warblers, juveniles can be reliably sexed (using throat patch color) approximately 15 days after fledging.

Feeding Habits
Golden-winged Warbler's diet consists mainly of insects such as caterpillars, moths, spiders, and especially leafroller caterpillars. They forage among foliage, using their sharp bills to probe into curls of leaves for concealed prey, and infrequently catch insects mid-flight.
Habitat
Golden-winged Warbler predominantly inhabit early-successional habitats like shrubby thickets and regenerating woodland areas. They are found in regions with a mixture of open and forested landscapes, favoring wet thickets, clearcuts, tamarack bogs, and stands of aspen or willow. These birds prefer areas at low to moderate elevations that undergo natural or anthropogenic disturbances, creating the desired patchy environment. During breeding, golden-winged Warbler nest in shrubland, whereas post-fledging they seek mature forests for protection. In the non-breeding season, they reside in semiopen woodlands and bird-friendly agricultural settings in their tropical wintering grounds.
Nest Behavior
Golden-winged Warbler females construct the nest over 1–3 days, often abandoning it if disturbed. Egg-laying patterns are sensitive to disruptions, with maternal care being paramount.
Nest Characteristics
Golden-winged Warbler typically nests on the ground, well-hidden by overhead vegetation. The cup-shaped nest is built by the female using leaves, bark, and plant strips, measuring 3.5 to 6 inches wide and 1 to 2.5 inches deep.

Behavior
Golden-winged Warblers exhibit a dynamic range of behaviors adapting to their habitats. They actively forage in brushy terrains, skillfully navigating foliage to locate prey, and are occasionally spotted performing acrobatics akin to chickadees. The breeding season ushers in pronounced behavioral shifts, with males becoming vocally and physically assertive to delineate territory, employing tail spreads, chases, and sometimes combat. Courtship sees males performing specific rituals, including crown-raising and slow wingbeat flights to woo mates. Post-mating, secrecy shrouds their nesting activities. Typically monogamous, golden-winged Warblers nevertheless have occasional reports of polygamy.
