Alexandrine Parakeet

Named in honor of Alexander the Great who brought specimens back to Macedonia in 326 BC, Alexandrine parakeets are among the largest and oldest documented pet parrots in history. They inhabit forest, woodland, and mangroves from Afghanistan and Pakistan east to Southeast Asia. Males display a distinctive pink-and-black neck ring. Listed as Near Threatened, with populations declining from severe capture pressure for the pet trade and habitat clearing. Feral populations exist across Europe.

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.
