The violet-throated glossy tail ( Metallura baroni ) or purple-throated glossy tail is a species of bird from the hummingbird family (Trochilidae). The species has a small distribution area in the South American country Ecuador . The stock is on the IUCN (as "critically endangered" Endangered ) classified.

features

The violet-throated glossy tail reaches a body length of about 8 cm, with the short, straight beak making up 1.3 cm. The upper side of the male has a bronze green sheen. There is a small white spot behind the eye. The throat and chest are glittering purple, occasionally covered with indistinct darker spots. The rest of the underside shimmers green. The tail is purple to blue bronze on the upper side and glittering green on the underside. The female is similarly colored, but with a little more yellow-brown scales on the underside. The throat is less purple in color than in the male.

Way of life

Most of the time, the violet-throated glossy tail travels alone . It moves in the lower strata , occasionally even on the ground. It often sits on branches that are relatively close to the ground. It clings to the flowers when absorbing nectar . The plants it flies to include the genera Duranta , Macleania , Tristerix and Castilleja .

distribution and habitat

Distribution area of ​​the violet-throated gloss tail

The violet-throated glossy tail is rarely or relatively often seen on the edges of mountain forests, including areas dominated by Polylepis . Furthermore, it occurs on the western slopes of the Andes in the province of Azuay in bushy páramo vegetation . It is most common in the Cajas National Park west of Cuenca . Observations have also been made in secondary vegetation in the canton of Oña in the south of Azuay, which is dominated by alders . Most of the reports about the violet-throated glossy tail come from altitudes of 3100 to 3700 meters.

Etymology and history of research

Osbert Salvin described the violet-throated shiny tail under the current name Metallura baroni . The type specimen came from near Cuenca and was collected by Oscar Theodor Baron (1847–1926), to whom the specific epithet is dedicated. The genus Metallura was introduced by John Gould in 1849.
