Habitat & Geographic Range

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.

Greenish Puffleg

Habitat

Typically found in various aerial, terrestrial, and aquatic environments.

Range

Distributed across Colombia, Ecuador, and Norway.

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.

Greenish Puffleg

A small, greenish hummingbird of humid Andean forests in Colombia, Ecuador, and Panama, greenish pufflegs are named for the distinctive white fluffy leg puffs — feather tufts on the tarsi — shared by all members of the puffleg genus Haplophaedia. They inhabit forest edges and secondary growth at elevations of 800–2,100 meters, foraging for nectar at small flowering plants in the understory. Listed as Least Concern with relatively stable populations across their range.
