Habitat and Ecology
It can be found in temperate shrubland and seasonal and permanent streams, in which it reproduces. It is not tolerant of habitat destruction.
It is locally common.
Urban sprawl is rapidly destroying available habitat for this species, and some populations close to the main cities (such as Santiago) have disappeared.
It has been included in the Chilean national legislation as near threatened and it occurs in Parque Nacional Cerro La Campana.
