Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

Weißbauchelfe

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.
