Chocoan Nectar Bat

The Chocoan Nectar Bat (Lonchophylla chocoana) is a small, highly specialised bat in the family Phyllostomidae, endemic to the Chocó biogeographic region of northwestern South America — one of the wettest and most biodiverse regions on the planet, spanning the Pacific lowlands of Colombia and Ecuador. It belongs to the genus Lonchophylla, a group of nectarivorous (nectar-feeding) bats characterised by an elongated snout, a long, brush-tipped tongue adapted for reaching deep into flowers, and reduced cheek teeth reflecting their liquid diet. Like other lonchophyllines, the Chocoan Nectar Bat plays an important ecological role as a pollinator of night-blooming plants whose flowers are adapted for chiropterophily (bat pollination), including species of Bromeliaceae, Cactaceae, and various other families. It roosts in caves, tree hollows, and dense vegetation in lowland and foothill forests of the Chocó. The IUCN classifies this species as Data Deficient, reflecting limited survey data on its distribution, population size, and ecology. The Chocó region, despite its extraordinary biodiversity, is under severe pressure from deforestation for palm oil and other agro-industrial crops, and any specialist bat dependent on intact forest and its flowering resources is potentially vulnerable to habitat loss.

Common Merganser

<em>Mergus merganser</em>, the common merganser or goosander, is a large diving duck in the family Anatidae, broadly distributed across Europe and North America. It is classified as Least Concern on the IUCN Red List. This species is capable of aerial, terrestrial, and aquatic locomotion, but is most specialized for underwater pursuit of prey. The common merganser is typically piscivorous, diving in clear, fast-flowing rivers and lakes to catch fish using its serrated bill, which provides a firm grip on slippery prey. Males display striking breeding plumage with a dark green head, white body, and red bill, while females are grey with a rusty-brown head and crested nape. The species nests in tree cavities, cliff ledges, and artificial nest boxes near freshwater habitats. It requires clean, well-oxygenated rivers and lakes for foraging, making it sensitive to water quality degradation and overfishing of prey species. Common mergansers are migratory in northern parts of their range, moving to coastal and ice-free inland waters during winter months.
