分布与栖息地
The Chilean mockingbird is found in Chile from Copiapó Province in the Atacama Region south to Los Lagos, Puerto Montt, and Chiloé Island. A small population also exists in Neuquén Province, Argentina.<p>The Chilean mockingbird inhabits a wide variety of biomes, most of which are characterized by scrub, shrubs, or widely spaced trees. Examples include succulent coastal scrub, inland savanna bushland, and evergreen Chilean matorral. It also occurs at the edges of low relict woodland patches such as those in Bosque de Fray Jorge National Park and in disturbed habitats, though only rarely in urban areas. It shuns Nothofagus and Cryptocarya woodlands in the south and plantations of introduced pines in central Chile. In elevation it ranges from sea level to 2,200 m (7,200 ft).

行为
The Chilean mockingbird forages mainly on the ground, turning over leaf litter and digging under fallen branches and around plant stems. It also hunts in vegetation up to 3 m (9.8 ft) above ground. It is omnivorous; it has been documented feeding on insects, wild and cultivated fruits, nectar, and a small lizard.<p>The Chilean mockingbird nests mainly in October and November. They are territorial, probably throughout the year. Their nest is a cup made of twigs lined with moss or wool, placed low in vegetion such as cacti and thorny bushes. The clutch size is two to four. The nest is often parasitized by shiny cowbirds (Molothrus bonariensis).<p>The Chilean mockingbird sings year round, "a series of sweet, variable notes and phrases". It is an "excellent mimic of other bird species."
