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, Venezuela).

White-bellied Woodstar

Habitat

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

Range

Distributed across Colombia, Ecuador, and Norway.

Epaulard

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.

White-bellied Woodstar

A tiny woodstar hummingbird inhabiting the Andes and inter-Andean valleys from Colombia to Bolivia, white-bellied woodstars are among the smallest hummingbirds with males weighing just 2.5 g. Males display a vivid amethyst-purple gorget and white belly with green flanks. Found at forest edges and gardens from 1,500–3,500 meters elevation. Despite their diminutive size, they are aggressive and highly maneuverable, entering torpor at night to conserve energy in cold Andean conditions.
