The Patagonian mockingbird (Mimus patagonicus) is a species of bird in the family Mimidae. It is found in much of Argentina and locally in Chile. The Patagonian mockingbird is 22 to 25 cm (8.7 to 9.8 in) long. Males weigh 44.4 to 61.8 g (1.57 to 2.18 oz) and females 43.8 to 65.4 g (1.54 to 2.31 oz). Adults have a brown crown, a whitish supercilium, and a blackish line through the eye. Their upperparts are plain grayish brown that is paler on the rump. The wings are blackish and show two thin pale bars when folded. Their tail is blackish except for the white outer edge of the outermost feathers and white tips on the others. They are buffy gray below that is paler on the throat and belly. The juvenile is essentially the same with the addition of blackish spots on the breast. The Patagonian mockingbird is a year round resident of northwestern and central Argentina. It breeds in southern Argentina and southern Chile as far as the Strait of Magellan and in the non-breeding season migrates north to central and somewhat into northeastern Argentina. It is a casual visitor to Tierra del Fuego and has been recorded in the Falkland Islands. The Patagonian mockingbird generally inhabits open shrublands and bushlands including the Patagonian steppe. In southeastern Argentina, it is also found in somewhat open woodland. In elevation it ranges from sea level to 1,800 m (5,900 ft).
