Pink-headed Warbler

The pink-headed warbler measures 12.5–13.5 cm (4.9–5.3 in) in length, and weighs 10 g (0.35 oz). Both sexes have a similar plumage, though females are, on average, slightly duller overall. The adult has dark red upperparts, a silvery-pink chest and pinkish-red underparts. Its head is silvery-pink, with a reddish forehead, dusky lores and dark brown irises. Its bill is blackish, sometimes showing some horn color on the lower mandible, and its legs are flesh-colored. The juvenile is a rich brown with slightly paler underparts. However, that plumage is quickly molted. Voice: The pink-headed warbler's call is high, thin, and somewhat metallic, variously transcribed as tsiu, ssing or tseeip. It also has a low, weak chip that it uses to stay in contact with its mate. Its song is a series of short trills and chips, described as being "clear and cheery" and reminiscent of the song of the yellow warbler, as well as slower and less varied than that of the red warbler.
