Black-thighed Puffleg

An Andean puffleg hummingbird named for the males' distinctive velvety black thighs contrasting with the characteristic white leg feather puffs, black-thighed pufflegs inhabit humid montane forest and forest edges in Ecuador and Colombia at elevations of 1,500–3,500 meters. Males display glittering green plumage with a violet-blue tail. Listed as Near Threatened due to deforestation of the Andean cloud forest, with populations declining as the specialized high-altitude forest habitat is cleared for agriculture.

Colombian Rhipidomys

<em>Rhipidomys caucensis</em>, commonly known as the Colombian Rhipidomys, is a small arboreal rodent species belonging to the genus <em>Rhipidomys</em> within the family Cricetidae. This species is classified as Data Deficient, reflecting a lack of sufficient information to accurately evaluate its conservation status, and indicating the need for further field investigation. It has been documented in Colombia, where it inhabits diverse terrestrial and aquatic-adjacent environments. Members of the genus <em>Rhipidomys</em> are typically arboreal, living in forest canopies and understories across the Andes and adjacent lowland regions of South America. These rodents are generally nocturnal and feed on a variety of plant materials including fruits, seeds, and other vegetative matter, though specific dietary records for <em>Rhipidomys caucensis</em> have not been documented. Biological traits of this species remain poorly documented in the scientific literature. The Data Deficient status underscores the importance of increased survey effort in Colombian forest ecosystems to better understand the distribution and ecological requirements of this arboreal rodent.
