The red-breasted brilliant hummingbird ( Heliodoxa aurescens ) or jeweled crown is a species of bird from the hummingbird family (Trochilidae) that is found in Venezuela , Colombia , Ecuador , Peru , Bolivia and Brazil . The IUCN assesses the population as Least Concern . The species is considered to be monotypical .

features

The red breast brilliant hummingbird reaches a body length of about 11 to 12 cm and a weight of 6.0 to 6.8 g. The beak is straight and dark in color. The male's forehead glitters violet-blue, the upper side shimmers grass-green. The underside with the chin, the reins and the upper part of the throat are velvet black. The sides of the neck and the lower area of ​​the throat glisten golden-green and are bordered by an orange-reddish brown chest band. The rest of the underside is shiny green. The central tail feathers of the forked tail are bronze-green, the rest of the chestnut-colored lined with bronze-green tips. The female is very similar, has less purple on the forehead and less glitter there. Occasionally there is no purple on the forehead at all. The chin and rein feathers have yellow-brown tips. In general, the plumage appears more dull. There are grayish to whitish sequins on the throat . In addition, a whitish yellow-brown to cinnamon-colored line adorns his cheek.

Behavior and nutrition

The red breast brilliant hummingbird gets its nectar from flowering undergrowth. He also hunts insects in flight by chasing them. In Brazil they have been observed on bromeliads of the species Bromelia balansae and plants of the genus Costus when nectar is taken up.

Vocalizations

The singing of the red breast brilliant hummingbird consists of a series of bright tones at a volume of approx. 9 kHz. The sounds sound like insects and sound like siii at a frequency of around 0.8 to one tone per second. The vocals contain liquid kwit and raspy chit tones.

Reproduction

The breeding season of the red breast brilliant hummingbird is from June to September. The clutch consists of two eggs and is only incubated by the female. In Bolivia the gonads were well developed in February, so it is very likely that it will also breed there between Agrigento and Villa Tunari during this time. In April, the gonadal formations of captured specimens at Cerro de la Neblina were described as only mediocre.

distribution and habitat

Distribution area of ​​the red breast brilliant hummingbird

The red breast brilliant hummingbird prefers the undergrowth of damp forests, especially near streams and damp places. You rarely see him at the edge of the forest or only occasionally in the middle of the tree tops. It can often be seen in sandy areas, occasionally in the Várzea forests. It occurs in tropical lowlands at altitudes of 150 to 400 meters, very rarely up to 900 meters. In Ecuador at the Wildsumaco Lodge it occurs regularly at altitudes around 1500 meters and in Peru around 1400 meters.

migration

The red-breasted brilliant hummingbird is commonly regarded as a resident bird .

Etymology and history of research

The first description of Rotbrust brilliant hummingbirds carried out in 1846 by John Gould under the scientific name Trochilus (Lampornis) aurescens . The type specimen was collected on the Rio Negro in Brazil. In 1850 Gould introduced the genus Heliodoxa u. 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 "aurescens" is derived from the Latin "aurescentis, aurescere, aurum" for "golden yellow, becoming golden, gold".

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.
