Collared Sunbird

The Collared Sunbird, known scientifically as <em>Hedydipna collaris</em>, is a small passerine bird belonging to the family Nectariniidae, the sunbirds. <em>Hedydipna collaris</em> is characterised by its iridescent plumage, with males typically displaying vibrant metallic green upperparts and a bright yellow belly separated by a purple collar band — a feature central to the species' common and scientific names. The species is primarily nectarivorous, feeding on nectar from flowering plants using its curved bill and brush-tipped tongue, and also consuming insects for protein. It inhabits forest edges, gardens, wooded savanna, and secondary vegetation across its range. It is reported to occur in Norway according to available range data. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Sunbird is currently assessed as Least Concern on the IUCN Red List.

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.
