Common Sword-nosed Bat

<em>Lonchorhina aurita</em>, the common sword-nosed bat, is a microchiropteran bat in the family Phyllostomidae, order Chiroptera. It is distributed across northern South America, with confirmed records from Colombia, Ecuador, and Venezuela, typically roosting in caves, tunnels, and hollow trees in humid tropical forests. The species is named for its exceptionally elongated, sword-like noseleaf, one of the most prominent of any bat species, which is thought to play a role in echolocation signal emission and directionality. <em>Lonchorhina aurita</em> is insectivorous, feeding primarily on insects captured in flight through echolocation within forested environments. It is typically gregarious, roosting in colonies that may include hundreds of individuals. Biological traits including average lifespan, body mass, and forearm length under field conditions remain poorly documented in the scientific literature. The species is assessed as Least Concern by the IUCN, with a reasonably broad distribution and populations that are not currently under severe threat, though continued deforestation and cave disturbance in South America may pose growing risks to local colonies over the long term.

Long-tailed Sylph

One of the most strikingly ornamented hummingbirds, male long-tailed sylphs have iridescent green plumage and dramatically elongated, ribbon-like outer tail feathers reaching up to 22 cm — over three times the body length. Found in Andean cloud forests of Colombia and Venezuela, they inhabit humid montane forest between 1,400–2,800 meters elevation. Males perform elaborate display flights to attract females. Their extravagant tails are a classic example of sexual selection via female preference.
