Brown Violetear

The only predominantly brown hummingbird in the violetear genus, brown violetears have brownish-bronze upper parts and a diagnostic violet-blue ear patch. Found across a broad range of humid forest and forest edge from Guatemala south through Venezuela, Colombia, and Brazil to Bolivia. Inhabiting elevations from lowland to 2,000 meters, they are found in forest interior, forest edge, and gardens. Despite relatively drab plumage for a hummingbird, the violet ear patch glitters vividly in direct sunlight.

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.
