This species is the eastern representative of the genus Teretistris, which is endemic to Cuba. It is a subtly attractive warbler, clad in plain gray over the crown and upperparts, with a yellow face and underparts, and possesses the genus’ characteristic decurved bill. The Oriente Warbler is distributed over the north-central littoral of the main island, then more widely over the extreme east of the island, and its range also encompasses several cays off the north shores of Cuba. It inhabits forests and scrub from sea level to the highest altitudes, just below 2000 m, and the Oriente Warbler is generally common and easily observed. Small flocks form outside the breeding season, sometimes with at least one Cuban Vireo (Vireo gundlachii) in attendance. The species breeds in March to July at least, when it builds a cup-shaped nest and lays 2–3 eggs.
