blue whale

Habitat

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

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Каштановая овсянка

Habitat

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

Range

Found in Norway.

blue whale

The largest animal ever known to have lived on Earth, blue whales can reach 33 meters and 200 tonnes — their hearts alone weigh as much as a small car. Found in all oceans, they migrate between polar feeding grounds and tropical breeding areas. Filter feeders consuming up to 4 tonnes of krill daily. Endangered, with global populations estimated at 10,000–25,000 after near-extinction from 20th-century whaling.

Каштановая овсянка

The cinnamon-breasted bunting (Emberiza tahapisi), also called the rock bunting or cinnamon-breasted rock bunting, is a small passerine in the family Emberizidae, widely distributed across sub-Saharan Africa and extending into the Arabian Peninsula and parts of western Asia. It inhabits rocky hillsides, boulder-strewn slopes, dry scrub, and open woodland with rocky outcrops, from sea level to highland elevations across its vast African range. The male is distinguished by bold streaky brown upperparts, a black and white striped head, and a rich cinnamon breast—its namesake feature. The species forages on the ground for seeds and invertebrates. The cinnamon-breasted bunting is classified as Least Concern by the IUCN, with a large, continuous African range and populations considered stable. It is one of the most widespread buntings in Africa. The species is entirely absent from Europe and Norway; database records to the contrary are errors arising from data entry or coordinate mistakes in species databases. This bunting is a common and conspicuous species throughout its African rocky habitat, often singing from prominent boulders. It is non-migratory across most of its range, though some montane populations may make limited altitudinal movements seasonally.
