Habitat & Geographic Range

baleine bleue

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.

Cisticole côtière

Habitat

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

baleine bleue

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.

Cisticole côtière

Cisticola haematocephalus, the coastal cisticola or red-headed cisticola, is a small passerine bird in the family Cisticolidae distributed across sub-Saharan Africa, inhabiting rank coastal and lowland grassland, tall reed beds adjacent to water bodies, and scrubby vegetation along rivers and wetland margins. The genus Cisticola, with over 50 species, represents one of the most speciose avian genera in Africa and is characterized by small, brown-streaked warblers that are notoriously difficult to distinguish in the field and are often best identified by voice. Cisticola haematocephalus is recognized by the rufous-chestnut crown that gives it its common and scientific names, distinguishing it from the numerous plain-crowned cisticola species with which it often shares habitat. Males perform conspicuous aerial display songs during the breeding season from exposed grass stems or in fluttering display flights. The species is assessed as Least Concern by the IUCN, being widespread across coastal and riverine lowlands of east, west, and central Africa. It constructs a characteristic deep, oval woven grass nest anchored within tall grass stems, often partially concealed by living grass folded around the nest entrance.
