Habitat and Ecology [top]

Habitat and Ecology:This species is an aerial insectivore. Common habitats for this species are native forested areas, such as sclerophyllous forest in northern Chile and Temperate forest in their southern distribution (Ossa and Rodriguez-San Pedro 2015). In arid and semiarid environments from northern Chile, M. chiloensis frequents watercourses for feeding (Mann 1978). However, in south-central Chile, this species is associated with evergreen-deciduous forests and temperate forests, respectively (Ossa and Rodriguez-San Pedro 2015).  In Argentina, this species was found beneath an abandoned bridge that crossed over a stream in riparian woodland within a Patagonian scrubland and roosting in an abandoned house in mixed stands of Nothofagus and Austrocedrus chilensis within the Valdivian Temperate Forest (Ossa and Rodriguez-San Pedro 2015).

Threats [top]

Major Threat(s): There are no major threats to this species throughout its range.

Conservation Actions [top]

Conservation Actions: A large part of its distribution range is covered under protected areas of distinct level, in Chile and Argentina. Research at several aspects is necessary.
