Commissaris's Long-tongued Bat

<em>Glossophaga commissarisi</em>, commonly known as Commissaris's Long-tongued Bat, is a small nectarivorous bat in the family Phyllostomidae. This species is classified as Least Concern on the IUCN Red List and is native to the Neotropical region, with populations recorded in Colombia and Ecuador, among other countries in Central and South America. As its name suggests, Commissaris's Long-tongued Bat is highly specialized for nectar feeding, possessing an elongated tongue and snout adapted for reaching deep into flowers. In doing so, it serves as an important pollinator for a variety of tropical plants, particularly those with tubular flowers that bloom at night. This bat typically inhabits tropical and subtropical forests, including humid lowland and montane forests, where flowering plants are abundant throughout the year. It often roosts in small groups within caves, hollow trees, or dense foliage. Biological traits of this species remain poorly documented in the scientific literature.

Common Eider

Common Eider (Somateria mollissima) is classified as Near Threatened (NT) on the IUCN Red List. Close to qualifying as threatened, with populations that may become vulnerable without conservation action.
