Chusquea Tapaculo

The Chusquea tapaculo (Scytalopus parkeri) is a small, secretive bird in the family Rhinocryptidae, endemic to the cloud forests of Ecuador. It inhabits dense bamboo thickets of Chusquea—the Andean bamboo genus for which it is named—as well as thick undergrowth in montane forest between approximately 2,200 and 3,000 meters elevation on the eastern Andean slopes. Like other tapaculos, it is almost entirely terrestrial, skulking through dense vegetation in search of insects and small invertebrates. The species is extremely difficult to observe and is typically detected by its distinctive song: a series of loud, repetitive notes that carry through dense forest. The Chusquea tapaculo is classified as Least Concern by the IUCN, with populations considered stable within its limited range. However, its dependence on intact cloud forest and bamboo understory makes it vulnerable to habitat loss from agricultural expansion and road-building in Ecuador's eastern Andes. The species was described relatively recently and named in honor of ornithologist Theodore Parker III. Tapaculos as a group are particularly sensitive to forest fragmentation because of their poor dispersal ability and strong site fidelity. Conservation of cloud forest corridors along the Ecuadorian Andes is essential for maintaining viable populations of this and many co-occurring endemic birds.

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.
