Habitat & Geographic Range

Cinnabar Boobook

Habitat

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

Range

Found in Norway.

Common Kidney-Vetch

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate broadleaf and mixed forests, and temperate coniferous forests, among 6 distinct biome types spanning the Indomalayan and Oceanian and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Libya), Asia (Japan), Europe (9 countries), North America (Canada, United States), and Oceania and the Pacific (Australia). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Cinnabar Boobook

The cinnabar boobook (Ninox ios) is a small owl in the family Strigidae, endemic to Sulawesi in Indonesia. It inhabits primary and mature secondary forest at low to mid elevations on the island, typically in humid lowland to foothill forest. Like other boobook owls, it is nocturnal, roosting in dense foliage during the day and hunting small vertebrates and invertebrates by night. The cinnabar boobook has rich rufous-brown upperparts and a distinctive reddish coloration that gives the species its evocative common name. The species is classified as Least Concern by the IUCN, with populations considered stable within its Sulawesi forest range. Sulawesi is a biogeographically remarkable island at the intersection of the Asian and Australian faunal zones, hosting a high proportion of endemic species. The island's forests face ongoing pressure from logging, mining, and agricultural encroachment, but the cinnabar boobook's adaptability to secondary forest provides some resilience. The species is entirely restricted to Sulawesi and does not occur in Europe; any database records listing Norway are data entry errors. The genus Ninox comprises the boobook owls of Australasia and Southeast Asia, with numerous island endemic species across Indonesia, the Philippines, and the Pacific islands.

Common Kidney-Vetch

Common Kidney-Vetch (<em>Anthyllis vulneraria</em>) is a flowering plant in the legume family Fabaceae, assessed as Vulnerable on the IUCN Red List due to habitat degradation and agricultural intensification across parts of its range. It is widely distributed across Africa (Libya), Asia (Japan), Europe (nine countries), North America (Canada and the United States), and Oceania (Australia), occupying six distinct biome types and occurring within the Indomalayan and Oceanian biogeographic realms. The species typically grows in dry, calcareous grasslands, coastal cliffs, sand dunes, and rocky slopes, often favoring nutrient-poor soils. It is an important larval food plant for certain butterfly species, particularly the Small Blue butterfly in Europe, and contributes to soil fertility through nitrogen fixation via root nodules. Its cheerful yellow, orange, or red flower heads make it a recognizable component of chalk and limestone grassland communities. Biological traits of this species remain poorly documented in the scientific literature.
