About Turdus grayi Bonaparte, 1838
In general appearance and habits, Turdus grayi resembles other Turdus thrushes such as the American robin. It measures 23–27 cm (9.1–10.6 in) in length, and is about the same length as the American robin or slightly smaller. On average, it weighs 74–76 g (2.6–2.7 oz). Its plumage is brownish, and is somewhat lighter on the underparts than the upperparts, with the lightest coloring found on its flanks. Individuals from humid regions are darker than those from dry regions. Its throat is faintly streaked. Immature birds have faint mottling on the back and underparts. The bill is greenish-yellow with a dark base, the legs are pinkish or flesh-colored, and the irises are reddish — all these features are useful for identification. Its distribution ranges from South Texas, where it is rapidly expanding its range, to northern Colombia. West and north of the Isthmus of Tehuantepec, it is limited to the Atlantic slope, with the exception of a population around Oaxaca City, Mexico that probably originates from escaped cage birds. Across much of its range, it is a common sight in yards and gardens, similar to other thrushes such as the American robin, the Eurasian blackbird, and the song thrush.
