Habitat & Geographic Range

Collared Puffbird

Habitat

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

Range

Distributed across Colombia, Ecuador, Norway, and Venezuela.

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.

Collared Puffbird

The Collared Puffbird, known scientifically as <em>Bucco capensis</em>, is a bird belonging to the family Bucconidae, the puffbirds. <em>Bucco capensis</em> is characterised by its rotund, large-headed appearance typical of puffbirds, with cryptic brown and rufous patterning and a distinctive collar that gives the species its common name. Puffbirds are typically sedentary, sit-and-wait predators, perching motionlessly for extended periods before lunging to capture prey including insects and small vertebrates. The Collared Puffbird is associated with tropical forest habitats in South America. It is reported to occur in Colombia, Ecuador, Norway, and Venezuela. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Puffbird is currently assessed as Least Concern on the IUCN Red List, indicating a stable population without significant global conservation concerns.

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.
