Hylocichla refers to a genus of North American birds commonly known as thrushes. Some synonyms for hylocichla include the wood thrush, veery, gray-cheeked thrush, olive-backed thrush, Bicknell's thrush, and Swainson's thrush. These birds inhabit forests and woodlands, where they forage for insects and fruit. The wood thrush is known for its flute-like song, which echoes through the forest. The veery's song is a series of descending spirals, while the gray-cheeked thrush's song is a series of piping notes. The olive-backed thrush has an olive-brown back, contrasting with its brighter orange underparts. Bicknell's thrush is a rare species that breeds in high-altitude forests, while the Swainson's thrush is a familiar migrant that nests in the far north.
