The copper tail ( Metallura theresiae ) is a species of bird from the hummingbird family (Trochilidae). The species is endemic to Peru . The IUCN classifies the population as “not at risk” ( least concern ).
features
The copper tail reaches a body length of approx. 11 cm and a weight of approx. 4.8 to 5 g. The male has a medium-sized straight black beak. The olive-bronze-colored top and bottom shows strong copper-red reflections, especially on the head. A narrow throat spot shimmers light green. The top of the tail shimmers violet-blue, the underside gray-violet. The female resembles the male, but the throat patch appears dull and incomplete. The outer control springs have white spots on the underside. Young birds are similar in color to the females.
Behavior and nutrition
Usually they buzz in front of black-mouthed plants like z. B. species of the genus Brachyotum or before heather plants such. B. Species of the genus Macleania . Males set up a food territory.
Vocalizations
Your hunting calls sound like a decreasing series of three to six squeaky tones. This is followed by repeated lively confused trt-tsi-sii-sii-sewm ... trr-tsi-tsew ... trr-tsi-tsew ... phases. The sounds are similar in structure to that of other members of the genus Metallura .
Reproduction
Increased gonadal development was detected in specimens between August and September . A clutch consists of two white eggs. The hatching occurs by the female. The first brood takes place in the second year of life of the animals.
distribution and habitat
They occur in open clearings with black mouth and heather scrub in damp dwarf and elf forest with moss and ferns. They can also be found on the bordering swampy grasslands. They get their food in the strata from the undergrowth to the treetops. They live at altitudes between 2900 and 3800 meters.
migration
Little is known about migration behavior. Presumably they are resident birds that migrate seasonally at high altitudes.
Subspecies
There are two known subspecies:
- Metallura theresiae parkeri Graves, GR , 1981 occurs in the Cordillera de Colán in northeastern Peru. In this subspecies the copper-red reflections are missing. She also has a green skull. The tail is sky blue on top and yellowish green on the underside.
- Metallura theresiae theresiae Simon , 1902 occurs in the northern Andes from the Amazon region to the Huánuco region.
Laticauda rubriginosa Cory , 1913, the type specimen of which was collected east of the village of Balsas by Wilfred Hudson Osgood and Malcolm Playfair Anderson , is now regarded as a synonym for the nominate form .
Etymology and history of research
Eugène Louis Simon described the shiny copper tail under the current name Metallura theresiae . The type specimen came from Tayabamba in the Pataz province in the La Libertad region and was collected by Gustave Adolphe Baer (1838-1918). In 1847 John 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 specific epithet theresiae is the wife of the collector Marie Thérèse Baer geb. Dedicated to Simon. Parkeri honors Theodore Albert Parker III (1953–1993). Rubriginosa is derived from the Latin »rubiginosus, rubigo, rubiginis, rubeus« for »rusty, rust-colored, rust, reddish«.
