The silver-browed mountain tangar ( Dubusia taeniata ) is a species of bird from the tangar family (Thraupidae). The species has a large range that includes the South American countries Venezuela , Colombia , Ecuador , Peru and Bolivia . The IUCN assesses the population as Least Concern .

features

The silver-browed mountain tangerine reaches a body length of about 19 centimeters with a weight of about 37 grams. The head, neck and throat are black. Most of the top is dark blue. A stringy pale metallic blue eyebrow arch extends long over the eyes. The yellow-brown chest band is not always noticeable. The rest of the bottom is yellow. The rump is also yellow-brown.

distribution and habitat

The species is rarely found in moss-covered and damp mountain forests. They can be found at altitudes between 1900 and 3500 meters. It can be seen mainly in the dense Chusquea bamboo that occurs in the Andes.

behavior

You can see the bird alone, in pairs and in mixed flocks. The territory in which it moves is very extensive. When looking for food, he jumps from branch to branch. He finds his food from the stratification layers at eye level up to the high treetops. Most of the time, it stays hidden in the thicket, even if it occasionally rests briefly in more open vegetation. The main food consists of small fruits and berries. It also feeds on mistletoe and insects that it finds in the moss.

Subspecies

Three subspecies are described, which differ mainly in their coloration and their range:

  • Dubusia taeniata taeniata ( Boissonneau , 1840) - nominate form , occurrence extends from the Sierra de Perijá in Venezuela, over all Andean slopes of the Departamento de Nariño in Colombia in the central Andes of Ecuador to the northwestern part of the Marañón Valley in Peru.
  • Dubusia taeniata stictocephala Berlepsch & Stolzmann , 1894 - The crown is clearly blue in contrast to the nominate form. Occurs in the Junín region in central Peru.
  • Dubusia taeniata carrikeri Wetmore , 1946 - Very similar to nominate form. The light brown of the chest extends to the cheeks. The blue of the brow stripes near the crown is much more intense. The middle and lower arm covers are darker. Shape a little smaller. Present in the valley of the Río Guatapurí and in the Sierra Nevada de Santa Marta .

At D. t. stictocephala , the South American Classification Committee has controversial opinions as to whether it is actually a species of its own.

Etymology and history of research

Auguste Boissonneau first described this mountain tangar as "Tanagra (Tachyphonus) tæniata". It was only later that Charles Lucien Jules Laurent Bonaparte added it to the genus »Dubusia« in his book Conspectus generum avium .

The genus was named by Bonaparte in honor of Baron Bernard Amé Léonard Du Bus de Gisignies (1808–1874). The silver-browed mountain tangare is the only species of this genus.

The epithet »taeniata« is derived from the Latin words »taenia« for »headband, ribbon«. The »carrikeri« in the subspecies honors Melbourne Armstrong Carriker, Jr. (1879–1965). The word »stictocephala« is derived from the Greek words »stictos« for »spotted, spotted« and »phalaris« for »blaze«.
