Common Big-eared Bat

The common big-eared bat (<em>Micronycteris microtis</em>) is a small insectivorous bat belonging to the family Phyllostomidae, native to tropical and subtropical regions of South America. Its range includes Colombia and Venezuela, where it typically inhabits diverse terrestrial and aquatic environments including forests and riparian zones. It is classified as Least Concern on the IUCN Red List, indicating a relatively stable population. As its common name suggests, <em>Micronycteris microtis</em> is distinguished by notably large ears relative to its body size, which enhance its echolocation capabilities for detecting prey and navigating complex forest environments. The species is often associated with lowland and foothill forests, roosting in caves, hollow trees, and dense vegetation. It typically feeds on insects and may also consume small vertebrates or fruit on occasion. Biological traits of this species remain poorly documented in the scientific literature.

Glowing Puffleg

A brilliantly colored puffleg hummingbird of the northern Andes from Colombia to southern Ecuador, glowing pufflegs display vivid iridescent green plumage that glows with an almost luminescent quality in bright light — inspiring the species' descriptive common name. Found in humid montane forest at elevations of 1,800–3,500 meters. Males have characteristic white leg puffs and a shimmering violet-blue tail. They are important pollinators of high-Andean flowering plants. Listed as Least Concern.
