The purple cap Hummingbird ( Gold Mania violiceps , sometimes) Gold shortcoming Libri called, is a species of bird from the family of hummingbirds (Trochilidae). The species has a small distribution area in Panama and Colombia . The IUCN assesses the population as Least Concern .

features

The violet-capped hummingbird reaches a body length of approximately 8.7 cm with a straight beak 1.8 cm long. The pink lower bill has black spots. The males have a predominantly green shimmer, with a bright blue skull. Near the sewer they have a tuft of white feathers. The slightly forked tail is colored chestnut red and traversed by broad golden bronze edges and spots. The top of the females is bright green. The underside is predominantly white, but is streaked with gray to green spots on the throat. There are also green spots on the sides. The under tail-coverts are green, whereby they also have the white tufts near the cloaca. The chestnut-red tail is broadly lined with bronze-green and has a bronze-colored subterminal band.

behavior

Little is known about the behavior of these hummingbirds. Usually the birds stay in the middle to lower strata within forests. They seem to be much more attracted to squeaking noises than other hummingbird species. They get their nectar from flowering bushes such as sage , or from bushes of the genus Pachystachis belonging to the acanthus family , the genus Palicourea belonging to the red family or the genus Psammisia belonging to the heather family .

Vocalizations

Alexander Wetmore described the males' call as a deep, extremely fast chirp.

Distribution area

The species occurs in the damp forests and forest edges of the eastern province of Colón z. B. on Cerro Bruja , the western part of San Blas on Cerro Brewster , in the province of Panamá Oeste on Cerro Azul and Cerro Jefe and in the east of the province of Darién on Cerro Tacarcuna . In recent research, violet- capped hummingbirds were also observed for the first time in the Serranía de Majé . In Colombia they occur at altitudes between 600 and 1400 meters on the eastern slopes of the cross-border Cerro Tacarcuna.

Etymology and history of research

On March 23, 1911, Edward Alphonso Goldman collected the type specimen at Cerro Azul in the northwest of the Chepo district , which Edward William Nelson described under the current name Goldmania violiceps . The name of the newly created genus was dedicated to its discoverer. The specific epithet »violiceps« is made up of the Latin words »viola« for »violet-colored« and »-ceps, caput«, »-krönt, head«.

Subspecies

There is no known subspecies of the violet-capped hummingbird. The species is therefore considered to be monotypical .
