Habitat & Geographic Range

Common Thin-toed Frog

Habitat

Typically found in freshwater habitats, moist forests, and wetlands.

Range

Found in Venezuela.

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.

Common Thin-toed Frog

<em>Leptodactylus leptodactyloides</em>, the common thin-toed frog, is an amphibian in the family Leptodactylidae, primarily recorded from Venezuela and surrounding lowland regions of northern South America. It is classified as Least Concern on the IUCN Red List. This terrestrial frog typically inhabits savanna grasslands, gallery forests, and disturbed areas adjacent to wetlands, where it breeds in temporary pools and flooded grasslands during the rainy season. Like other leptodactylid frogs, males call from the water's edge to attract females, and the species produces foam nests for eggs. Diet typically consists of invertebrates including insects, spiders, and worms. The species is part of a diverse and taxonomically complex genus, and population status across its range is not precisely quantified. Biological traits such as adult body length, weight, lifespan, and clutch size remain poorly documented in comprehensive standardized scientific assessments for this species specifically. Conservation efforts benefit from broader amphibian monitoring programs across Venezuela and the surrounding region.

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.
