The fiery-throated tail ( Metallura eupogon ) is a species of bird in the hummingbird family (Trochilidae) that is endemic to Peru . The IUCN assesses the population as Least Concern . The species is considered to be monotypical .

features

The shiny fire-throated tail reaches a body length of about 11 cm, with a weight of 5 g. The male has a medium-long straight black beak. The top and bottom are almost entirely yellowish olive green with a bronze shimmer. The narrow throat patch is orange. The tail is shimmering sky blue with a green tint on the top and a yellow-green tint on the underside. The female is very similar but the throat patch is imperfect. The outer control springs have light-colored tips. Young animals resemble the females.

Behavior and nutrition

The fiery-throated glossy tail gets its nectar from plants similar to those of the shale-belly glossy tail . For example, B. the nectar of Brachyotum ledifolium to its nectar sources.

Reproduction

In June to July, shiny fire-throated tails with enlarged gonads were examined. A clutch consists of two white eggs that are incubated by the female.

Vocalizations

The hunting call sounds almost identical to that of Kupferglanzschwänzchens ( Metallura Theresiae Simon , 1902) and the shed abdominal Glanzschwänzchens ( Metallura aeneocauda ( Gould , 1846)). The song consists of a decreasing series of three to six squeaky tones, which repeated lively disorderly phrases such as trt-tsi-sii-sii-su..trr-tsi-tsi tsu..trr-tsu .. sound, follow . The structure is similar to other members of the genus.

distribution and habitat

Distribution area of ​​the Feuerkehl-Glanzschwänzchen

The fiery throated tail prefers open forest meadows with black- mouthed and heather scrub in moss-coated dwarf and elf forest , which alternates with Andean grass plains ( pajonal ) and habitat with scrub along the tree line. It also roams around in the adjacent Páramo grassy landscape. It moves at altitudes between 2900 and 4000 meters: it is most commonly found above 3500 meters.

migration

The fiery-throated shiny tail is usually considered a resident bird , even if no reliable data is available. It is believed that it may migrate between high altitudes as a seasonal line bird .

Etymology and history of research

The first description of the fire-throated gloss tail was in 1874 by Jean Louis Cabanis under the scientific name Urolampra eupogon . The type specimen was collected by Konstanty Roman Jelski at Maraynioc . In 1847 Gould introduced the new genus Metallura . The word Metallura is derived from the Greek words »metallon μεταλλον « for »metal« and »oura ουρά « for »tail«. The species name eupogon is a Greek word formation from "eu ευ " for "fine, beautiful" and "pōgōn, pōgōnos πωγων, πωγωνος " for "beard".
