Commerson's Leaf-nosed Bat

<em>Macronycteris commersonii</em>, commonly known as Commerson's Leaf-nosed Bat, is a chiropteran mammal in the family Hipposideridae. This species is assessed as Near Threatened on the IUCN Red List, indicating that it faces increasing pressures that could elevate its risk of extinction without conservation attention. Commerson's Leaf-nosed Bat typically inhabits a range of diverse ecosystems across sub-Saharan Africa, including forests, savannas, and areas near caves or rocky outcrops that serve as roosting sites. Like other hipposiderid bats, it uses echolocation to navigate and hunt in low-light conditions, often foraging for insects in open or semi-open environments after dark. Roost disturbance, habitat degradation, and human persecution are among the primary threats facing this species. The large, elaborately shaped noseleaf characteristic of the family helps focus echolocation signals during foraging. Populations are typically found roosting in caves, mines, and hollow trees in groups that may range from small colonies to large aggregations. Biological traits of this species remain poorly documented in the scientific literature.

Scaly-naped Parrot / Scaly-naped Amazon

A large, predominantly green amazon parrot with distinctive dark-scaled nape feathers and a patch of red on the wing, scaly-naped amazons inhabit humid montane forests of the northern and central Andes in Colombia, Venezuela, Ecuador, and Peru at elevations of 600–3,000 meters. Relatively little known compared to other amazons, they are found in pairs or small flocks feeding on seeds, fruit, and flowers in cloud forest. Listed as Least Concern.
