The beard hooked beak ( Diglossa mystacalis ) is a bird art from the family of tanagers (Thraupidae). The species occurs in Bolivia and Peru . The IUCN assesses the population as Least Concern .
features
The beard hook bill reaches a body length of about 13 to 14.5 centimeters. The plumage is mostly glossy black. The rump is tinted blue-black. There is a reddish-brown line of beard below the cheeks. The upturned black beak has a hook-shaped tip.
distribution and habitat
The birds are found in cloud forests and the bushes of humid páramo at altitudes between 2,400 and 3,700 meters. You can often see them at the edges of the forest near the tree line.
behavior
They are only on the move in pairs during the breeding season, otherwise they are considered loners. They can be seen acrobatically climbing between branches before heading for the next tree. Reports indicate that they prefer to explore the corollas of the heather family . When foraging, they are mostly in the lower stratification layers and collect below the leaves. They are very territorial and scare away other species as well. When they chirp, they are sitting in the bush crowns or protruding branches.
Subspecies
So far, four subspecies are known, which differ mainly in their coloration:
- Diglossa mystacalis mystacalis Lafresnaye, 1846 ( nominate form ). Occurs in the departments of Cochabamba and La Paz .
- Diglossa mystacalis pectoralis Cabanis , 1873. This subspecies is found from the Panao district in the Pachitea province in the Huánuco region to Junín . Most closely resembles D. m. unicincta . The chest band is also reddish brown in the upper part, but becomes white in the lower half.
- Diglossa mystacalis albilinea Chapman , 1919. This subspecies is present in the Peruvian regions of Ayacucho , Cusco and Puno . Very similar to the nominate shape, but the beard stripe is ocher-colored or creamy white in the front area. Another difference is the gray shoulders.
- Diglossa mystacalis unicincta Hellmayr , 1905. This subspecies occurs in the Cordillera de Carpish in the Huánuco department in central Peru. The streak of beard is white. In addition, the birds have a reddish brown chest band, belly and cloaca .
