About Setophaga citrina (Boddaert, 1783)
The hooded warbler (Setophaga citrina) is a small, mid-sized warbler species. It measures 13 cm (5.1 in) in length, weighs 9–12 g (0.32–0.42 oz), and has a wingspan of 17.5 cm (6.9 in). This species has a plain olive to green-brown back and yellow underparts. The vanes of its outer rectrices are whitish. Adult males have a distinctive black hood that surrounds their yellow face, while females have an olive-green cap that does not extend to the forehead, ears, or throat. Males develop their characteristic black hood at around 9 to 12 months of age; younger birds are essentially identical to females and easily confused with them. The hooded warbler's song is a sequence of musical notes that sounds like wheeta wheeta whee-tee-oh, and common mnemonics for this song are "The red, the red T-shirt" or "Come to the woods or you won't see me". The call of this bird is a loud chip.
