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.

Cinderella Waxbill

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.

Cinderella Waxbill

The Cinderella waxbill (Estrilda thomensis) is a small passerine bird in the family Estrildidae, endemic to São Tomé Island in the Gulf of Guinea, off the western coast of Central Africa. It inhabits forest edges, secondary growth, gardens, and cultivated areas with dense low vegetation, where it forages for grass seeds and small invertebrates, typically in small flocks. The species shares its common name with its delicate, finely patterned plumage featuring a gray crown, red bill, dark mask, and rusty-pink flanks, suggesting an ornate appearance reminiscent of the fairy tale character. The Cinderella waxbill is classified as Least Concern by the IUCN, with populations considered stable on São Tomé, where it is one of the more commonly encountered endemic birds in modified habitats. São Tomé and Príncipe together represent one of Africa's most important island biodiversity hotspots, with remarkable levels of avian endemism resulting from long isolation. The island's endemic waxbill benefits from its adaptability to secondary and garden habitats, tolerating a degree of human land use. Conservation of remaining native forest on São Tomé is critical for the many forest-dependent endemic species on the island. The species is occasionally kept by aviculturalists but is not a major target of the wild bird trade.
