Habitat & Geographic Range

Cinnamon-chested Bee-eater

Habitat

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

Range

Found in Norway.

Common Silver Hairgrass

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Cameroon), Asia (Japan, South Korea), Europe (6 countries), North America (4 countries), Oceania and the Pacific (Australia), and South America (4 countries). Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Cinnamon-chested Bee-eater

The cinnamon-chested bee-eater (Merops oreobates) is a colorful, aerial insectivore in the family Meropidae, endemic to the highlands of East Africa. It is found in Uganda, Kenya, Tanzania, Rwanda, Burundi, and eastern DRC, typically at elevations between 1,500 and 3,000 meters in montane forest edge, woodland clearings, and cultivated areas with tall trees. Like all bee-eaters, it is a masterful aerial hunter, catching bees, wasps, and other flying insects in fast pursuit flights from open perches. The plumage is brilliant—green upperparts, a bright blue rump and undertail, a distinctive cinnamon-rufous chest, and a black gorget separating the throat from the breast. The species is classified as Least Concern by the IUCN, with stable populations across the East African highlands. It often nests colonially, digging burrows into earthen banks or flat ground. The cinnamon-chested bee-eater is absent from Europe; Norwegian database records are data entry errors. This bee-eater is a popular species with birdwatchers visiting the East African highlands, often observed conspicuously from perches at forest edges. Conservation of highland forest and woodland habitats, and the retention of earthen banks for nesting, are beneficial for this species.

Common Silver Hairgrass

<em>Aira caryophyllea</em>, commonly known as Common Silver Hairgrass, is a slender annual grass belonging to the family Poaceae within the order Poales. This delicate grass is currently classified as Endangered on the IUCN Red List, reflecting significant conservation concern despite its historically broad distribution. It is typically found across a remarkable diversity of biome types, including tropical and subtropical moist broadleaf forests, grasslands, savannas, and flooded habitats, demonstrating notable ecological versatility. Its geographic range spans multiple continents, with documented populations in Africa (Cameroon), Asia (Japan, South Korea), Europe, North America, Australia, and South America. As an annual grass, it completes its life cycle within a single growing season, reproducing via wind-dispersed seeds. The inflorescence typically bears silvery, shimmering spikelets that give the species its common name. Biological traits such as average lifespan, body dimensions, and dietary specifics follow typical patterns for annual grasses — drawing nutrients from soil through root absorption rather than consuming other organisms. The endangered status suggests populations may be declining due to habitat loss, land-use change, or invasive species pressure across parts of its range.
