Emperor Penguin

The world's largest penguin, emperor penguins stand up to 1.2 meters and weigh 45 kg, inhabiting the Antarctic continent in some of the most extreme conditions on Earth. They breed in midwinter darkness at temperatures below -60°C, with males incubating single eggs on their feet under a brood pouch for 65 days while females are at sea. Their huddling behavior — cycling individuals through the warm center of thousands-strong groups — is a masterclass in cooperative survival.

Green Hermit

A large hermit hummingbird of humid rainforest in Central America and the northern Andes, green hermits are named for the males' predominantly green plumage — unusual among hermits which are generally brown and buff. Females have blue-green upper parts and rufous underparts. Found from Costa Rica to Peru and Venezuela at elevations up to 1,600 meters in forest understory. They are important pollinators of large Heliconia and Calathea flowers along the forest floor, following established trap-line routes.
