baleine à bosse

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.

Percefleur à flancs blancs

A medium-sized flowerpiercer of humid Andean cloud forest and forest edges from Colombia south to Bolivia, white-sided flowerpiercers have distinctive white flank patches contrasting with dark grey-blue plumage. Like all flowerpiercers, they use their sharply hooked and slightly upturned bill to pierce the base of tubular flowers and steal nectar without pollinating — earning them the reputation as nectar thieves. Found at elevations of 1,500–3,500 meters, they are commonly encountered in Andean gardens and forest edges.
