Koala

Iconic marsupial of eastern and southeastern Australia, koalas weigh up to 15 kg and spend up to 22 hours daily sleeping to conserve energy from their low-calorie eucalyptus leaf diet. Highly specialized to process toxic eucalyptus compounds that would kill most other mammals, they have gut microbiomes uniquely adapted for detoxification. Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.

Chinasittich

One of the largest parakeets in the world, Lord Derby's parakeets display distinctive blue-green plumage with a striking red-and-black banded bill and a long pointed tail reaching over 60 cm. They inhabit montane forests at 1,000–4,000 meters elevation across the eastern Himalayas, southwest China, and northern Myanmar. Listed as Vulnerable due to deforestation and trapping, they are prized aviary birds. They are known to breed cooperatively with related pairs assisting dominant breeders.
