Common yellowthroat
The common yellowthroat (Geothlypis trichas) is a New World warbler. It is an abundant breeder in North America, ranging from southern Canada to central Mexico. In the northern parts of its range the birds are migratory, wintering in the southern parts of the breeding range, Central America and the West Indies. Southern forms are largely resident. Historically, it has also known as the "yellow bandit", Maryland yellow-throat, and yellow-breasted warbler.
The common yellowthroat was formally described in 1766 by the Swedish naturalist Carl Linnaeus in the twelfth edition of his Systema Naturae under the binomial name Turdus trichas. The specific epithet is from Ancient Greek τριχας/trikhas, τριχαδος/trikhados, a type of thrush. Linnaeus based his account on "The Maryland yellow-throat" that had been described and illustrated in 1758 by the English naturalist George Edwards in his book Gleanings of Natural History. Linnaeus specified the locality as North America but this was restricted to the state of Maryland by the American Ornithologists' Union in 1931. The common yellowthroat is now one of 15 species placed in the genus Geothlypis that was introduced in 1847 by the German ornithologist Jean Cabanis. The genus name combines the Ancient Greek γεω-/geō- meaning "ground-" or "earth-" with θλυπις/thlupis, an unknown small bird.
Thirteen subspecies are recognised:
Common yellowthroats are small songbirds that have olive backs, wings and tails, yellow throats and chests, and white bellies. Adult males have black face masks which stretch from the sides of the neck across the eyes and forehead, which are bordered above with white or gray. Females are similar in appearance, but have paler underparts and lack the black mask. Immature birds are similar in appearance to the adult female. First-year males have a faint black mask which darkens completely by spring.
The subspecies mainly differ in the males' facial patterns and the brightness of the yellow underparts. The southwestern subspecies of this bird are the brightest and the yellowest below.
The song is a loud twichety twichety twichety twich. Its call is a soft jip.
Measurements:
Common yellowthroats breed in marshes and other wet areas with low, dense vegetation. They may also be found in other areas with dense shrubs, and are less commonly found in dry areas. Females appear to prefer males with larger masks. Common yellowthroats nest in low vegetation, laying 3–5 eggs in a cup-shaped nest. Both parents feed the young.
