The rufous-backed thrush (Turdus rufopalliatus) is a songbird of the thrush family. It is endemic to the Pacific slope of Mexico. It is also known as the rufous-backed robin. This species resembles its widespread relative the American robin in general appearance, but is a bit smaller at 21.5–24 cm long, with an average wingspan of 39.4 cm and weight of 74 g. It is named for the adult's rufous or olive-rufous upper back, which contrasts with the grayish head, nape, and rump. The chest and flanks are also rufous. The belly and undertail coverts are white; the throat is white with many black streaks. The bill and eye-ring are yellow. Females are typically somewhat duller-colored than males. Juveniles, like other juvenile Turdus thrushes, are spotted below; they are browner and have pale flecks above. The song is slow and warbling, with repetition of phrases. An example is "weedele loo loo freerlii..." The alarm call is a long, mellow, descending whistle, "cheeoo or teeeuu".Other calls resemble those of the American robin; the flight call is thinner.
