Identificazione

The hooded warbler is a small bird and mid-sized warbler, measuring 13 cm (5.1 in) in length and weighing 9–12 g (0.32–0.42 oz). The hooded warbler has a wingspan of 6.9 in (17.5 cm). It has a plain olive/green-brown back and yellow underparts. Their outer rectrices have whitish vanes. Males have distinctive black hoods which surround their yellow faces; the female has an olive-green cap which does not extend to the forehead, ears, and throat. Males attain their hood at about 9–12 months of age; younger birds are essentially identical to (and easily confused with) females. The song is a series of musical notes which sound like: wheeta wheeta whee-tee-oh, for which a common mnemonic is "The red, the red T-shirt" or "Come to the woods or you won't see me". The call of these birds is a loud chip.

Tassonomia

The French polymath Georges-Louis Leclerc, Comte de Buffon described the hooded warbler in 1779 in his Histoire Naturelle des Oiseaux from a specimen collected in Louisiana. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Muscicapa citrina in his catalogue of the Planches Enluminées.<p>The hooded warbler was formerly placed in the genus Wilsonia. A molecular phylogenetic study of the family Parulidae published in 2010 found that the hooded warbler was embedded in a clade that contained species then assigned to Dendroica as well as two of four species of Parula and the monotypic genera Catharopeza and Setophaga. To create a monophyletic genus, all members of the clade were placed in the expanded genus Setophaga, which under the rules of the International Code of Zoological Nomenclature, had priority. The genus Setophaga was introduced by the English naturalist William Swainson in 1827.The species is monotypic; no subspecies are recognised. The genus name Setophaga is from Ancient Greek ses, "moth", and phagos, "eating", and the specific citrina is Latin for citrine.
