The tepuidean wing ( Campylopterus duidae ), sometimes also called mountain sword or cream-colored sword wing , is a species of bird from the hummingbird family (Trochilidae). The species has a large range that includes the South American countries Brazil and Venezuela . The IUCN assesses the population as Least Concern .
features
The Tepuidegen wing reaches a body length of about 12 centimeters. The black beak is up to 22 millimeters long. The top is gold-green, with the top of the head containing fewer gold-colored elements. There is a white spot behind the eye. The underside is reddish gray. The flanks and the sides of the neck are golden. The lower tail-coverts and the tip parts of the outer control feathers are graduated in pale looser colors. So three quarters are looser on the outermost pair, half on the second and only one third on the third pair. The rest of the tail feathers are reddish gold bronze in color. The feet are brown.
distribution and habitat
This hummingbird occurs in the higher altitudes of the tropical and subtropical zones at altitudes between 1200 and 2400 meters. The natural habitat is the cloud forest . Here it preferably moves near clearings and forest edges in the thicket and mossy forests close to the ground. It builds its nest at heights between 2 and 3 meters above the ground.
Subspecies
So far, two subspecies are known, which differ mainly in their color.
- C. d. duidae Chapman , 1929- The nominate form occurs in the upper tropical and subtropical zones of the central and southern Venezuelan state of the Amazon . Here you can see them in the mountains Yaví , Parú , Huachamacari , Duida and de la Neblina . They are also common in neighboring Brazil in the states of Roraima and Amazonas .
- C. d. guaiquinimae Zimmer & Phelps , 1946 - The subspecies differs from the nominate form by a dark underside, which is more reddish than reddish-gray. The tail end is noticeably darker. They are only found on the tepuis on Mount Guaiquinima at altitudes between 1220 and 1700 meters in central Bolívar and on the Río Paragua in southern Venezuela.
Etymology and history of research
Frank Michler Chapman described the hummingbird under the current name Campylopterus duidae . The type specimen was collected on January 7, 1929 by the brothers Alfonso and Ramón Olalla. "Campylopterus" is a Greek structure from "kampylos καμπύλος " for "bent, curved" and "-pteros, pteron πτερο " for "-fluted, wing". "Duidae" describes the location of the "Cerro Duida". »Guaiquinimae« also refers to the site »Cerro Guaiquinima«. Here Sivio Benedetti had collected the bellows on February 4, 1945.
