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.

Greenish Puffleg

A small, greenish hummingbird of humid Andean forests in Colombia, Ecuador, and Panama, greenish pufflegs are named for the distinctive white fluffy leg puffs — feather tufts on the tarsi — shared by all members of the puffleg genus Haplophaedia. They inhabit forest edges and secondary growth at elevations of 800–2,100 meters, foraging for nectar at small flowering plants in the understory. Listed as Least Concern with relatively stable populations across their range.
