Taxonomy and systematics
The genus name Augastes comes directly from the
Description
The hooded visorbearer is a small hummingbird, measuring 8.3–10 cm (3.3–3.9 in) in length and weighing 4–4.8 g (0.14–0.17 oz).
Voice
The song of the hooded visorbearer is described as "nasal" and "dry". Transcribed as tru tweé tru zee, its short phrases are typically repeated more than three times in a row.[11]
Range and habitat
The hooded visorbearer is endemic to eastern Brazil.[5] Found only in the Chapada Diamantina region of Bahia, it is restricted to campo rupestre,[14] a high-elevation ecoregion that is characterized by poor soils, open vegetation, rocky outcrops and harsh climatic conditions.[15] Its occurs at elevations ranging from 900 to 2,000 m (3,000 to 6,600 ft),[11][14] and is considered to be one of South America's obligate grassland birds.[16] It is found in rocky, semi-arid areas with cactus and low shrubs on the summits of mountains and mesas.[11][17]
Behavior
Feeding
Like all hummingbirds, the hooded visorbearer feeds primarily on nectar, though it will also take insects. It typically forages low, often less than 1 m (3 ft 3 in) from the ground.[10] It is known to visit Vriesea flowers early in the day, while the flowers (which are primarily bat-pollinated) still hold some residual nectar.[18]
Breeding
Little is known of the breeding ecology of the hooded visorbearer. It builds its nest from cactus spines, usually about a metre (just over three feet) off the ground.[19]
Conservation and threats
For several decades in the 20th century, the species was thought to have gone
Relationship with humans
The hooded visorbearer is considered to be among the handful of birds in the Chapada Diamantina that prove particularly attractive to birdwatchers. Trails have been created in the Chapada Diamantina National Park to enable ecotourists to enter the habitat in which they are found.[21]
