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.

Slate-colored Grosbeak

A large, heavy-billed seed-eating bird of humid lowland forest in the Amazon basin, Central America, and northern South America, slate-colored grosbeaks have uniform dark slate-grey plumage with a powerful, pale bill. Despite their name, they are placed in the saltator genus. They inhabit dense, humid forest interior and forest edge, foraging in pairs or small groups on large seeds and hard fruits. Their powerful bills crack seeds too tough for most other birds. Listed as Least Concern.
