Habitat & Geographic Range

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.

Chirping Cisticola

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.

Chirping Cisticola

The Chirping Cisticola (Cisticola pipiens) is a small, warbler-like bird belonging to the family Cisticolidae, one of the most diverse passerine families in the Old World. Members of the genus Cisticola are characterised by their cryptic brown-and-buff streaked plumage, slender bills adapted for gleaning insects from vegetation, and remarkably loud vocalisations relative to their diminutive size. The chirping cisticola inhabits wetland margins, reedbeds, and tall grasslands across sub-Saharan Africa, where it constructs intricate oval nests stitched together with plant fibres and spider silk. Like other cisticolas, it feeds primarily on small invertebrates including beetles, moths, and their larvae, foraging actively among dense grasses and sedges. The species undertakes short seasonal movements in response to rainfall patterns, following the flush of insect productivity that accompanies wet conditions. Males perform conspicuous song-flights during the breeding season, ascending above the grassland canopy before descending in a characteristic display. The IUCN classifies the Chirping Cisticola as Least Concern, reflecting its broad distribution and tolerance for a range of grassland and wetland habitats. Populations appear stable, though localised declines may occur where wetland drainage and agricultural conversion reduce available nesting sites.
