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.

Common Dwarf Bonneted Bat

<em>Eumops bonariensis</em>, the common dwarf bonneted bat, is a small molossid bat classified as Least Concern on the IUCN Red List, suggesting its populations are currently not under significant threat. The species has been recorded in Venezuela and is associated with diverse terrestrial and aquatic habitats, reflecting the broad ecological tolerance typical of many molossid bats. <em>Eumops bonariensis</em> belongs to the free-tailed bat family Molossidae and is characterized by its distinctive bonnet-shaped ears that extend over the forehead. Like other members of its genus, this species is adapted for fast, high-altitude flight and typically forages for flying insects in open airspace above forest canopies, wetlands, and urban areas. Molossid bats are known for their echolocation calls, which they use to detect and pursue prey during nocturnal foraging bouts. The species typically roosts in tree cavities, rock crevices, or man-made structures, forming small to moderate-sized colonies. Its insectivorous habits make it an important regulator of insect populations in tropical and subtropical ecosystems. Biological traits of this species remain poorly documented in the scientific literature.
