Habitat & Geographic Range

Choco Screech Owl

Habitat

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

Range

Distributed across Colombia and 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.

Choco Screech Owl

The Choco Screech-Owl (Megascops centralis) is a small, cryptically patterned owl in the family Strigidae, found in the humid lowland and foothill forests of the Chocó region of northwestern Colombia and extending into adjacent areas of Central America. Screech-owls of the genus Megascops are characterised by their small to medium size, prominent ear tufts, complex camouflage plumage imitating tree bark, and vocalisations consisting of mellow trilling or whinnying calls quite different from the piercing screech suggested by their common name. The Choco Screech-Owl inhabits the forest interior and edge from sea level to around 1,500 metres elevation, where it hunts nocturnally for large insects, small lizards, frogs, and occasionally small birds. During the day it roosts upright against a tree trunk or in dense foliage, where its mottled grey, brown, and black plumage renders it nearly invisible. Nesting occurs in natural tree cavities. The IUCN classifies this species as Least Concern, with a sufficient range across the Colombian Chocó and Central America. However, the ongoing loss of lowland tropical forest in this region — one of the wettest on Earth — remains a background threat to this and the many other Chocó endemics that depend on intact forest.

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.
