Habitat & Geographic Range
Brown Violetear
Typically found in various aerial, terrestrial, and aquatic environments.
Distributed across Colombia, Ecuador, Norway, and Venezuela.
Cock-tailed Tyrant
Typically found in various aerial, terrestrial, and aquatic environments.
Found in Norway. 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.
Cock-tailed Tyrant
The cock-tailed tyrant (Alectrurus tricolor) is a striking and unusual flycatcher in the family Tyrannidae, named for the remarkable elongated, spatula-shaped outer tail feathers of the male, which can exceed the body length and are displayed during aerial courtship flights over open grasslands. The species inhabits wet and seasonally flooded grasslands, cerrado savanna, and campos in the interior of South America, including central Brazil, eastern Bolivia, Paraguay, and northeastern Argentina — not Norway, as erroneous database entries suggest. Males combine conspicuous black, white, and rufous plumage with their extraordinary tail streamers in an elaborate display to attract females on leks; females are cryptically streaked brown. The cock-tailed tyrant is a ground- and low-vegetation forager, preying on insects and other small invertebrates gleaned from grass stems and caught in aerial sallies. The species is classified as Vulnerable by the IUCN due to extensive and continuing conversion and degradation of its native Neotropical grassland habitat through intensive soy and sugarcane agriculture, cattle ranching, fire management changes, and drainage of seasonally flooded grasslands. Populations have declined significantly across much of its range, particularly in Brazil and Paraguay. The species is a flagship for threatened grassland conservation in South America, where relatively little protection has historically been directed at open-country habitats compared to forest ecosystems.
