Blue-tailed Emerald

A small, jewel-like hummingbird named for the brilliant blue-green iridescence of the tail feathers, male blue-tailed emeralds display glittering green plumage throughout with a contrasting deep blue-green forked tail. Found in lowland tropical forest edges, savannas, and gardens from Venezuela and Colombia east to Trinidad and south to Bolivia and Brazil. They are common in disturbed and secondary habitats, making them relatively resilient to habitat modification compared to more specialized hummingbirds.

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.
