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.

Buff-breasted Mountain-Tanager

A medium-sized mountain tanager of Andean cloud forests, buff-breasted mountain tanagers have warm buff-orange underparts contrasting with deep blue-black upper parts and wings, creating a striking warm-cool color contrast. Found in humid montane forest at elevations of 2,000–3,600 meters from Venezuela south to Bolivia. They inhabit forest interior and edge, foraging in pairs and small groups on fruit and insects in the mid-canopy. They often join mixed-species flocks. Listed as Least Concern.
