Long-tufted screech owl

The long-tufted screech owl (Megascops sanctaecatarinae) is a species of "typical owl" in the subfamily Striginae. It is found in Argentina, Brazil, and Uruguay.

The long-tufted screech owl is 25 to 28 cm (9.8 to 11 in) long. Males weigh 155 to 194 g (5.5 to 6.8 oz) and females 174 to 211 g (6.1 to 7.4 oz). It is a fairly large and bulky member of Megascops, with stronger feet than most others. It occurs in three color morphs of which the brown one predominates over the gray and rufous. It has very prominent "ear" tufts. The upperparts of the common morph's adult are dark brown with pale, coarse, indistinct vermiculation; its crown is somewhat lighter. The brown facial disc has a darker border. The underparts are a mix of irregular bars, streaks, and vermiculation in shades of brown. The eye is pale yellow to orange-yellow, the bill greenish gray, and the feet pale grayish brown. The plumages of the gray and rufous morphs and the juvenile have not been formally described.
