Érione de Derby

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.

Mangouste naine

<em>Helogale parvula</em>, the common dwarf mongoose, is the smallest mongoose species in Africa and belongs to the family Herpestidae. Classified as Least Concern by the IUCN, the species maintains stable populations across diverse terrestrial and aquatic habitats throughout sub-Saharan Africa, though specific geographic range data for this entry are limited. <em>Helogale parvula</em> is a highly social carnivore that typically lives in cooperative family groups of up to thirty individuals, led by a dominant breeding pair. The group structure supports cooperative foraging, pup-rearing, and sentinel behavior, with designated individuals standing watch for aerial and terrestrial predators while others forage. Common dwarf mongooses are diurnal and typically shelter in termite mounds, rock crevices, or hollow logs, moving between multiple den sites within their territory. They play an important ecological role as predators of insects, small vertebrates, eggs, and other invertebrates, contributing to the regulation of prey populations in savanna and woodland ecosystems. Their mutualistic associations with hornbills, in which both species benefit from shared foraging and predator detection, are among the most studied interspecific relationships in behavioral ecology. Biological traits of this species remain poorly documented in the scientific literature.
