Black-and-white Seedeater

A small, boldly patterned seedeater with striking black-and-white plumage in males — jet black upper parts and wings contrasting with white underparts — black-and-white seedeaters inhabit open and semi-open habitats including grassland, forest edge, and plantation shade in the Andes from Colombia to Bolivia. One of the more distinctively patterned Sporophila seedeaters. Females are plain brown and buff. They forage on grass seeds and are sometimes kept as cage birds for the males' patterning and song.

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.
