The stock is on the IUCN as endangered ( Vulnerable estimated). The species is considered to be monotypical .

features

The red-throated brilliant hummingbird reaches a body length of about 11 to 12 cm. The male has a straight black beak. The upper side shimmers green with a middle line on the front skull. There is a small white spot behind the eye. The underside shimmers green, the throat has a glittering pink-red stain. The belly is gray, the under tail-coverts whitish. The long tail is forked and bronze in color. The female is similar to the male but has a smaller throat patch.

Behavior and nutrition

The red-throated brilliant hummingbird gets its nectar and a. of flowering plants of the genus Psittacanthus and the belt flower family . It also feeds on insects.

Vocalizations

The singing of the red throated brilliant hummingbird presumably consists of a nasal keuf tone, which it emits at a frequency of one tone per second. In flight or when feeding, it also makes these sounds individually.

Reproduction

Little is known about the breeding biology of the red throated brilliant hummingbird. Only in eastern Ecuador was a fully fledged cub reported at the beginning of November that was still being looked after by its mother.

distribution and habitat

Distribution area of ​​the Rotkehl brilliant hummingbird

The red star brilliant hummingbird prefers moist mountain forests at altitudes of 250 to 1050 meters. These are mainly found in the foothills in southern Colombia in the departments of Cauca and Putumayo and in northeastern Ecuador in the western part of the provinces of Sucumbíos and Napo . There are also reports from northeastern Peru in the Loreto region , the Amazon region and the north of the San Martín region .

migration

The red-throated brilliant hummingbird is generally regarded as a resident bird , but there is a lack of reliable data.

Etymology and history of research

The first description of Rotkehl brilliant hummingbirds was in 1860 by John Gould under the scientific name Aphantochroa? gularis . The type specimen was collected on the banks of the Río Napo . As early as 1850 Gould introduced the genus Heliodoxa a . a. for the violet-forehead brilliant hummingbird . This name is derived from the Greek words "hēlios, ἡλιος " for "sun" and "doxa, dekhomai δοξα, δεχομαι " for "splendor, glory, approve". The species name "gularis" is derived from the Latin "-gular, gula" for "-throat, throat".

Remarks

  1. ↑ In addition to the violet- browed brilliant hummingbird, he also classified the green- browed brilliant hummingbird ( Heliodoxa jacula Gould , 1850), the brown-bellied brilliant hummingbird ( Heliodoxa rubinoides ( Bourcier & Mulsant , 1846)) and the ruby hummingbird ( Clytolaema rubricauda ) (Syn. 1783) ( Boddaert , 17 : Heliodoxa rubinia Gould , 1850) to the new genus. With the subspecies Heliodoxa leadbeateri otero , Gould did not seem entirely sure.
