About Turdus subalaris (Seebohm, 1887)
Turdus subalaris, commonly called the blacksmith thrush, measures 20 to 22.5 cm (7.9 to 8.9 in) in length and weighs 46 to 55 g (1.6 to 1.9 oz). This species shows clear sexual dimorphism. Adult males have a mostly gray head, an orange-yellow to brown eye-ring, and a white throat streaked with black. Their upperparts, wings, and tail are gray; their breast is a lighter gray, and their belly and vent are white. Adult males have a dark brown iris, an orange-yellow to brown bill with orange-yellow patches, and yellowish brown to brownish gray legs and feet. Adult females are very similar to males, but differ in having a yellowish green to olive brown eye-ring and somewhat paler upperparts. They have a dark brown iris, a pale yellowish brown to black bill, and pale yellowish brown to pale brownish olive legs and feet. Juveniles have olive-brown upperparts marked with orange-brown spots. Their throat and breast are pale orange-yellow with blackish feather edges, their belly is white with blackish bars, their iris is brown, their bill is olive-black, and their legs and feet are gray to reddish gray. The blacksmith thrush is distributed in eastern South America: it occurs in Brazil from southeastern Mato Grosso, northern Goiás, and southwestern Bahia southward, through eastern Paraguay, and into Misiones Province of northeastern Argentina. The South American Classification Committee also documents records of this species from Uruguay. It inhabits forest (especially Araucaria groves), tall woodlands, gallery forest, and parks and gardens with tall trees. Across its range, it occurs from near sea level up to 1,600 m (5,200 ft), but it is mostly found below 1,000 m (3,300 ft) within Brazil.
