Habitat & Geographic Range

Coastal Miner

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.

Coastal Miner

Geositta peruviana, the coastal miner, is a small passerine bird in the family Furnariidae native to the hyperarid coastal desert of Peru, one of the driest places on Earth. The species inhabits the Atacama and Peruvian coastal desert zone, occurring along the entire Peruvian coast from sea level up to several hundred meters elevation on the coastal slopes of the western Andes, where sparse vegetation and sandy or rocky substrate provide nesting and foraging habitat. Miners in the genus Geositta are ground-dwelling birds that excavate nest tunnels in sandy banks and flat ground, laying eggs at the end of the tunnel in a grass-lined chamber. The coastal miner forages on bare ground and among sparse desert vegetation for small insects, seeds, and invertebrates. It is part of a guild of small ground birds highly specialized to the Peruvian coastal desert, which despite its extreme aridity supports a unique assemblage of endemic vertebrates. The species is assessed as Least Concern by the IUCN, being relatively common and widespread throughout its desert coastal range. The Furnariidae, the ovenbirds, are one of the most diverse bird families in South America, comprising over 300 species that have radiated into an extraordinary range of habitats and ecological niches across the continent.

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.
