Cocoa Thrush

The cocoa thrush (Turdus fumigatus) is a medium-sized thrush in the family Turdidae, native to the tropical forests, gardens, and woodland edges of the Lesser Antilles and northern South America, including Trinidad, Tobago, Venezuela, Guyana, Suriname, French Guiana, and northern Brazil. Like other Turdus thrushes, it is primarily a ground and low vegetation forager, consuming earthworms, insects, berries, and small fruits; its melodious, flute-like song is a characteristic sound of its forest and garden habitats. The species is named for its plain, smoky-brown plumage — fumigatus meaning smoke-coloured in Latin — with little differentiation between sexes. It inhabits primary and secondary forest, cocoa and citrus plantations, and shaded gardens, showing tolerance for modified land use that has allowed it to persist in many humanised landscapes. Nesting occurs in trees or shrubs; clutches are typically two to three eggs, incubated by the female alone. The cocoa thrush has no natural presence in Norway; country-level database records to that effect are artefacts. It is classified as Least Concern by the IUCN, with wide distribution and stable or increasing populations in some areas due to its adaptability to modified habitats. It is closely related to the similar cocoa thrush assemblage of Turdus thrushes found across the Neotropics, and taxonomy within the group has been subject to ongoing revision.

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.
