Habitat & Geographic Range

Серый земляной тиранн

Habitat

Typically found in various aerial, terrestrial, and aquatic environments.

Range

Found in Norway.

Common corncockle

Habitat

Found across multiple habitat types including montane grasslands and shrublands, tropical and subtropical moist broadleaf forests, and temperate coniferous forests, among 13 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Lesotho), Asia (7 countries), Europe (24 countries), North America (Canada, Mexico, United States), Oceania and the Pacific (Australia), and South America (Brazil, Chile). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Серый земляной тиранн

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.

Common corncockle

<em>Agrostemma githago</em>, commonly known as common corncockle, is an annual flowering plant in the family Caryophyllaceae. Once a widespread weed of cereal crops across Europe, Asia, and beyond, this species is now Critically Endangered on the IUCN Red List due to the dramatic decline caused by modern agricultural practices, particularly improved grain cleaning and herbicide use. Corncockle is a tall, slender plant covered in silky white hairs, bearing large, solitary pink to purple flowers with distinctive dark veining. Its seeds contain toxic saponin compounds called githagins, which historically contaminated grain supplies. The species now survives primarily in wildflower conservation areas, seed banks, and traditional farmland conservation schemes. It typically grows in open, disturbed arable soils with full sun exposure. Biological traits of this species remain poorly documented in the scientific literature.
