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-throated Saltator

A large, handsome saltator of humid forest, forest edge, and secondary woodland from Mexico through Central America and south to Bolivia and Brazil, buff-throated saltators display green upper parts with a distinctive white supercilium, black malar stripe, and warm buff throat. They are common in forest margins and gardens, producing rich, melodious warbling songs. They forage on seeds, fruit, and buds, occasionally joining mixed-species flocks. One of the most frequently observed saltators across their broad neotropical range.
