Blue Dacnis

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.

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.
