The black-necked tangar ( Tangara labradorides ) is a species of bird from the family of the tangar (Thraupidae). The species has a large range that includes the South American countries Colombia , Ecuador and Peru . The IUCN assesses the population as Least Concern .
features
The black-necked tangar reaches a body length of about 13 centimeters. Most of the plumage looks silver-green to silver-blue, depending on how the light falls. The crown and a wide eye stripe are opalescent green to straw gold. The eye mask, the center of the crown and the nape of the neck are black. The black shoulders, arm feathers and tail feathers have green borders. The edges are predominantly blue only on the arm wings. The middle part of the abdomen and the under tail covers are yellow-brown to cinnamon in color.
distribution and habitat
The species is rarely found in moist mountain forests. Mostly it moves in the treetops at the forest edges and secondary vegetation of the subtropical zone at altitudes between 1300 and 2200 meters.
behavior
The bird is very active and acrobatically climbs between thin branches and twigs. It also hangs and flutters on the outer foliage and examines the underside of the leaves for arthropods . Usually he is out in pairs or in smaller groups. You can often see it together with other species of tangerine. In contrast to most other tanagers, it is not a downright forest bird.
Subspecies
Two subspecies are described, which differ mainly in their coloration and their area of distribution:
- Tangara labradorides labradorides (Boissonneau, 1840) - nominate form . Occurs in Colombia on the slopes of the western, eastern and central Andes. In Ecuador only present on the western slopes south to the province of Pichincha .
- Tangara labradorides chaupensis Chapman , 1925 The general color is greener. The belly is much paler. The whitish area extends to the chest and most of the abdomen. The parting either has a minimal or no golden sheen. The edges on the wings are gold green instead of blue. The distribution area is the southeast of Ecuador to the northwest of the Peruvian province of Huancabamba . The first specimen described came from Chaupe .
Naming
Auguste Boissonneau first described this shimmering tangar under Tanagra (Aglaia) labradorides . The name comes from Latin and describes the typical color of the labradorite .
