Habitat & Geographic Range

Brown Violetear

Habitat

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

Range

Distributed across Colombia, Ecuador, Norway, and Venezuela.

Coastal Rocket Frog

Habitat

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

Range

Found in Venezuela. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Brown Violetear

The only predominantly brown hummingbird in the violetear genus, brown violetears have brownish-bronze upper parts and a diagnostic violet-blue ear patch. Found across a broad range of humid forest and forest edge from Guatemala south through Venezuela, Colombia, and Brazil to Bolivia. Inhabiting elevations from lowland to 2,000 meters, they are found in forest interior, forest edge, and gardens. Despite relatively drab plumage for a hummingbird, the violet ear patch glitters vividly in direct sunlight.

Coastal Rocket Frog

Coastal rocket frog (Allobates bromelicola) is a small terrestrial frog in the family Allophrynidae (formerly placed in Dendrobatidae), endemic to coastal lowland forests of Venezuela. Despite its placement near poison dart frogs, Allobates species are non-toxic. This species inhabits the humid leaf litter and bromeliads of coastal Venezuelan forests, where adults care for egg clutches and transport tadpoles to small water bodies including bromeliad phytotelmata. The genus Allobates is widespread across Amazonian and coastal South American forests, characterised by vocal males, ground-level activity, and close parental care. Coastal rocket frog is assessed as Vulnerable by the IUCN, primarily due to restricted range, habitat loss from deforestation for agriculture, livestock grazing, and urban expansion along Venezuela's coast. Climate change poses an additional threat through altered precipitation patterns affecting its bromeliad microhabitats. The species' specific association with bromeliads makes it particularly sensitive to vegetation structure loss. As with many narrowly endemic amphibians, ex-situ conservation programmes and improved habitat protection within its range are considered important management priorities.
