Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

Ruddy-breasted Seedeater

A tiny, chestnut-red seedeater of open grasslands, weedy fields, and marshes distributed across Central America and most of South America east of the Andes to Argentina, ruddy-breasted seedeaters have warm rufous-red plumage in males with darker wings. Among the most widely distributed Sporophila seedeaters, they thrive in disturbed agricultural landscapes and secondary growth. They forage in small to large flocks on grass seeds and cereal crops. Least Concern with populations benefiting from agricultural expansion.
