Синеголовый красногузый попугай

One of the most colorful Pionus parrots, blue-headed parrots display a vivid cobalt blue head and neck contrasting with green body plumage and red undertail feathers. Found in humid lowland and foothill forests from southern Mexico through Central America and across northern and western South America. They inhabit forest, forest edge, and mangroves, traveling in noisy flocks to fruiting trees. Popular aviary birds for their quiet, gentle demeanor relative to many other parrots.

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.
