Range

Widely distributed across Europe (8 countries), Oceania and the Pacific (Australia), and South America (Colombia, Ecuador).

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.

Zebra Finch

One of the most popular cage birds worldwide, zebra finches are small, seed-eating songbirds native to arid and semi-arid grasslands across mainland Australia and the Lesser Sunda Islands. Males display distinctive orange cheek patches, red beaks, and barred flanks. Highly social, living in flocks that may number thousands in the wild, zebra finches are fundamental model organisms in neuroscience research on vocal learning, song development, and the neural basis of learning and memory.
