About Setophaga tigrina (J.F.Gmelin, 1789)
Setophaga tigrina, commonly known as the Cape May warbler, is a small passerine bird and a mid-sized New World warbler. Its body length ranges from 12 to 14 cm (4.7 to 5.5 in), wingspan from 19 to 22 cm (7.5 to 8.7 in), and body mass from 9 to 17.3 g (0.32 to 0.61 oz). Standard measurements are as follows: wing chord 6.1 to 7.3 cm (2.4 to 2.9 in), tail 4.3 to 5 cm (1.7 to 2.0 in), bill 0.9 to 1.2 cm (0.35 to 0.47 in), and tarsus 1.7 to 1.9 cm (0.67 to 0.75 in). Adult male Cape May warblers have a brown back, yellowish rump, and dark brown crown. Their underparts are yellow with black streaks, which is the origin of the species' scientific name. The throat and nape are bright yellow, and the face has a distinctive chestnut patch bordered by yellow, with a black eyestripe. Adult males also have a narrow white wing bar. The plumage of females and immature males looks like a faded version of adult male plumage, and they do not have the strong head pattern seen in adult males. The yellowish rump and at least faint signs of the white wing bar are always present in these birds.
