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.

Manx Shearwater

Habitat

Typically found in diverse ecosystems where prey species are available.

Range

Found across Europe (5 countries) and South America (Colombia, Ecuador).

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.

Manx Shearwater

A medium-sized seabird of the North Atlantic and North Pacific, Manx shearwaters are renowned for their extraordinary navigation abilities. They travel up to 1 million kilometers over a lifetime, migrating annually between breeding colonies on North Atlantic islands and wintering grounds off South America. Their stiff-winged shearing flight just above wave surfaces is characteristic. One individual lived for over 55 years, one of the longest-lived wild birds recorded.
