Dacnis bleu

A brilliantly colored tanager-like bird of tropical South America, male blue dacnis display vivid turquoise-blue plumage with a black back and throat, while females are green. Found in humid forest canopy and forest edges from Colombia and Venezuela south to Bolivia and Brazil. They inhabit the treetop foliage foraging for fruit, berries, and small insects, often joining mixed-species feeding flocks. They are important seed dispersers for small-fruited trees in Amazonian and Atlantic Forest ecosystems.

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.
