Choco Yellow-shouldered Bat

The Choco Yellow-shouldered Bat (Sturnira koopmanhilli) is a medium-sized frugivorous bat in the family Phyllostomidae, endemic to the Chocó biogeographic region of northwestern South America, where it occurs in the humid forests of the Pacific slope of Colombia and adjacent Ecuador. It belongs to the genus Sturnira — the yellow-shouldered bats — characterised by males bearing distinctive yellowish, orange, or reddish shoulder glands (from which the group's name derives), robust bodies, and rounded ears. Like all Sturnira, this species is primarily frugivorous, consuming a wide range of small, soft fruits from pioneer and forest trees, and plays an important role as a seed disperser in disturbed forest patches and forest edges. The diet of Solanaceae (nightshade family) fruits is particularly typical of the genus, and Sturnira bats are considered the primary dispersers of many pioneer Solanum species in Neotropical secondary succession, contributing directly to forest regeneration. The IUCN classifies the Choco Yellow-shouldered Bat as Data Deficient, reflecting significant uncertainty about the species' distribution limits, population size, and ecological requirements. The Chocó region continues to experience rapid deforestation, which threatens frugivorous bat diversity even where individual species lack adequate data for formal threat assessment.

Cinnabar Boobook

The cinnabar boobook (Ninox ios) is a small owl in the family Strigidae, endemic to Sulawesi in Indonesia. It inhabits primary and mature secondary forest at low to mid elevations on the island, typically in humid lowland to foothill forest. Like other boobook owls, it is nocturnal, roosting in dense foliage during the day and hunting small vertebrates and invertebrates by night. The cinnabar boobook has rich rufous-brown upperparts and a distinctive reddish coloration that gives the species its evocative common name. The species is classified as Least Concern by the IUCN, with populations considered stable within its Sulawesi forest range. Sulawesi is a biogeographically remarkable island at the intersection of the Asian and Australian faunal zones, hosting a high proportion of endemic species. The island's forests face ongoing pressure from logging, mining, and agricultural encroachment, but the cinnabar boobook's adaptability to secondary forest provides some resilience. The species is entirely restricted to Sulawesi and does not occur in Europe; any database records listing Norway are data entry errors. The genus Ninox comprises the boobook owls of Australasia and Southeast Asia, with numerous island endemic species across Indonesia, the Philippines, and the Pacific islands.
