The subtropical doradito (Pseudocolopteryx acutipennis) is a species of bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Bolivia, Brazil, Colombia, Ecuador, Paraguay, and Peru. The subtropical doradito is 11 to 12 cm (4.3 to 4.7 in) long and weighs 7 to 10 g (0.25 to 0.35 oz). Both sexes have a short shaggy crest, and both have the same plumage. Adults have a mostly bright olive head, upperparts, and tail; their cheeks are dusky. Their wings are olive-brown with light gray edges on the flight feathers and dull cinnamon tips on the wing coverts; the last show as two faint wing bars. Their throat and underparts are golden-yellow. Both sexes have a dark brown iris, a slender, black, warbler-like bill, and dark gray legs and feet. Immatures are similar to adults but with more prominent buffy wing bars and a pale base to the mandible. The subtropical doradito has a disjunct distribution. It is found in Colombia's Central Andes, in the central Andean valley of Ecuador between Imbambura and Chimborazo provinces, locally in Peru's central Andes, and from Peru's southern Andes south through central Bolivia, western Paraguay, and southern Brazil into northwestern Argentina. It primarily inhabits reedbeds, marshes, wet pastures and fields with sedges, and brushy areas near water. It also occurs in grassy areas that have few sedges. In elevation it ranges between 1,500 and 2,800 m (4,900 and 9,200 ft) in Colombia, between 2,400 and 3,500 m (7,900 and 11,500 ft) in Ecuador, between 1,400 and 3,200 m (4,600 and 10,500 ft) in central Peru, below 1,000 m (3,300 ft) in southern Peru, and below 700 m (2,300 ft) in Brazil.
