Orange-headed Tanager
Thlypopsis sordida
The orange-headed tanager is a small, thin-billed tanager that has an average length of 13 cm (5.1 in) and a weight of 14–19 g (0.49–0.67 oz). Its proportions are similar to those of a New World warbler. Males of the nominate subspecies have rufous-orange crowns and sides of the head, becoming bright yellow on the lores, ocular region (area surrounding eye), and throat. The upperparts are sandy-gray, with dusky primary coverts and flight feathers, the latter of which are edged with gray. Voice: The orange-headed tanager's calls include a high-pitched tseet, seet, or sit, often given rapidly multiple times, a quick high-pitched chittering sit-it-t-t-t-t-t-t, and a slower seet-a.
