Траурная вьюрковая овсянка

A small, boldly patterned seedeater with striking black-and-white plumage in males — jet black upper parts and wings contrasting with white underparts — black-and-white seedeaters inhabit open and semi-open habitats including grassland, forest edge, and plantation shade in the Andes from Colombia to Bolivia. One of the more distinctively patterned Sporophila seedeaters. Females are plain brown and buff. They forage on grass seeds and are sometimes kept as cage birds for the males' patterning and song.

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.
