Nashville Warbler, watercolor on 300lb paper. The Nashville Warbler is a small, energetic songbird found across much of North America during migration, breeding in the northern United States and Canada, and wintering in Mexico and Central America. Despite its name, it has no particular connection to Nashville, Tennessee — it was simply first described there by ornithologist Alexander Wilson in 1811. It is a compact bird with olive-green upperparts, a bright yellow throat and underparts, and a distinctive white eye ring that stands out sharply against its gray head. Males sport a partially hidden rusty-brown patch on their crown, which is rarely visible in the field. One of its most distinguishing features is the lack of white wing bars, setting it apart from many similar warblers. Its song is a lively, two-parted series of high-pitched notes often described as "see-bit, see-bit, see-bit, titititi," and it tends to be an active forager, flitting through shrubby vegetation and forest edges in search of insects and caterpillars.
