Жако, серый попугай

Widely regarded as the most intelligent parrot species and the most capable avian mimic, African grey parrots can develop vocabularies of over 1,000 words and demonstrate comprehension of concepts including zero, color, shape, and relative size. Native to equatorial African rainforest from Ivory Coast to Kenya, they live in large flocks. Endangered due to catastrophic trapping for the pet trade — up to 21% of wild birds are trapped annually — and deforestation. Strict CITES Appendix I trade restrictions apply.

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.
