Arrowhead Warbler

The arrowhead warbler is 12.5 to 13 cm (4.9 to 5.1 in) long and weighs 9.1 to 10.5 g (0.32 to 0.37 oz). The sexes have almost the same plumage. Adult males have a black and white streaked head and upperparts. The upper side of their wings is darker and the greater and median coverts have white tips that show as two wing bars. Their tail is mostly dark above with a whitish underside and white spots at the tips of the outer two pairs of feathers. Their underparts are mostly whitish with the eponymous black arrowheads on the throat, breast, and flanks. Adult females are slightly duller than males, and at least one source states that their streaks are gray rather than black. Both sexes have a dark iris, a blackish bill, and blackish brown legs and feet. Immature birds have brownish yellow upperparts with faint yellowish buff streaks. Their wings and tail are darker than adults', and their underparts are pale brownish yellow with faint darker streaks.

The arrowhead warbler is endemic to Jamaica. It inhabits humid montane forest and also humid lowland forest in the non-breeding season.

The arrowhead warbler feeds primarily on insects. It forages at all levels of the forest, gleaning prey from leaves, vines, and branches.

The arrowhead warbler's genus Setophaga means "moth eater" in Greek. The specific epithet pharetra is Latin and means "quiver" as in a carrier for arrows.
