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.

Slate-colored Seedeater

A small, slate-blue seedeater of open grasslands, savannas, and forest edges from Nicaragua through Central America and along the Pacific slope of South America to Bolivia, slate-colored seedeaters have uniform dark slate-grey plumage in males with a pale bill. They forage in small flocks on grass seeds and are often found in tall grass near forest edges. Like many Sporophila seedeaters, they are impacted by trapping for the cage bird trade and habitat loss from pasture conversion.
