The purple- throated glossy tail ( Metallura odomae ) or Neblina glossy tail is a species of bird from the hummingbird family (Trochilidae). The species has a limited range in the South American countries Ecuador and Peru . The population is classified as “ Least Concern ” by the IUCN .

features

The purple-throated glossy tail reaches a body length of about 9 cm, with the short, straight beak making up 1.5 cm. The male has a dark green bronze shine on the upper side and has a small white spot behind the eye. The throat glitters reddish purple. The underside looks dull bronze-green, with the feathers often scaly brown-yellow. The under tail feathers are lined with reddish tones. The tail is bronzed bluish green on the top and light green on the underside. The coloring of the females is similar to that of the males, but the top of the tail is more bronze in color. The underside is scaled a little more whitish to yellow-brown.

Way of life

The males of the purple-throated glosstail seem to be outnumbered. The behavior is like that of the Green Shiny Tail and the Emerald Throat Shiny Tail . The relatively aggressive little hummingbird moves and usually sits at heights between 1 and 5 meters. To get to the flower nectar , it is more likely to cling to the flowers than to buzz in front of them. When it comes to defending the blooms on bushes and hedges near forest edges, the behavior is cautious but territorial .

distribution and habitat

Distribution area of ​​the purple-throated gloss tail

The species occurs only very locally in forest areas near the tree line in the Andes of the province of Zamora Chinchipe and the neighboring province of Loja . It was only discovered in 1989 by Michael Kessler in the Podocarpus National Park . Here it seems to occur relatively frequently in the humid Páramo near the Lagunas del Compadre . There are further observations from Cerro Toledo . Occasionally she was seen as far as the border with Peru. Smaller populations have also been spotted in the Río Angashcola valley to the south of Loja. Most of the sightings come from altitudes of 2950 to 3400 meters, but also at 3650 meters.

Vocalizations

The call sounds like a descending series of four to five zi tones, followed by further disordered tones.

Etymology and history of research

Gary Russell Graves described the purple- throated glossy tail under the current name Metallura odomae . The type specimen came from the vicinity of Cerro Chinguela and was prepared by Richard D. Semba . The genus Metallura was introduced by John Gould in 1849. The specific epithet is dedicated to Babette Moore Odom (1911–1984), who financially supported several research trips to Peru.
