Habitat & Geographic Range

Chocoan Nectar Bat

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Range

Distributed across Colombia and Ecuador.

Eurasian Skylark

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, tundra, and tropical and subtropical moist broadleaf forests spanning the Australasia and Oceanian realms.

Range

Widely distributed across Europe (5 countries), North America (Canada, United States), and Oceania and the Pacific (Australia, New Zealand). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

Eurasian Skylark

Celebrated across European literature and poetry for its complex, melodious song sung on the wing during spectacular display flights, Eurasian skylarks soar vertically hundreds of meters above open farmland, grassland, and heathland across Europe and Asia while producing an uninterrupted torrent of song lasting up to an hour. Males can produce over 700 distinct song phrases. Once enormously abundant across European farmland, skylark populations have declined over 70% since 1970 due to agricultural intensification.
