Cinereous Ground-Tyrant

The cinereous ground tyrant (Muscisaxicola cinereus) is a small flycatcher in the family Tyrannidae, found in the high Andes and Patagonian grasslands of South America, with a range spanning Chile, Argentina, Bolivia, and Peru. It inhabits open, barren, or sparsely vegetated habitats such as high-altitude puna grassland, rocky Andean plateaus, rocky coastal grassland, and steppe vegetation, typically at elevations from 1,000 meters to above 4,500 meters. Like other ground tyrants, it forages on the ground for insects and small invertebrates, often running and pausing rather than perching. The plumage is uniform gray to brownish-gray with a slightly paler underside. The cinereous ground tyrant is classified as Least Concern by the IUCN, with a wide South American range and stable populations. Ground tyrants of the genus Muscisaxicola represent a fascinating adaptive radiation into high-altitude open habitats across the Andes and southern South America. This species is entirely restricted to South America and is absent from Europe; any database record citing Norway is incorrect. Andean grassland habitats face increasing pressure from overgrazing, burning, and climate-driven changes in vegetation, but the cinereous ground tyrant's wide range and tolerance of degraded habitats suggest resilience.
