The black- hooked beak ( Diglossa venezuelensis ) is a species of bird in the tangar family (Thraupidae). The range of this endemic species is limited to the South American country Venezuela . The stock is on the IUCN as endangered ( Endangered estimated).
features
The black hook beak reaches a body length of about 12.7 to 13.5 centimeters. The plumage of the male is almost completely black and has white tufts on the abdomen. It also has a white line on the wings. The female has a yellow-olive colored head. The rest of the top is olive brown. The throat and breast are matt dark olive-yellow and merge into olive-brown in the rear part of the underside. The white tufts and the wing stripe is similar to that of the male. The upturned black beak has a hook-shaped tip on both.
distribution and habitat
The crested beak can be found in damp forest edges, relatively new to advanced secondary vegetation and shrubbery near the forest at heights between 1525 and 2450 meters. It has so far been observed in the Cordillera de Caripe and the Pariah Peninsula . It is believed that the bird is only found in areas where clusia as well as other herbs dominate.
behavior
The bird usually appears nervous and hyperactive. In doing so, he gets his nectar from practically all stratification layers . Most of the time, however, it is looking for food in the middle layers of the bush. You can often see it close to the ground in the thicket of the heliconias . He travels alone and in pairs. It is not usually seen with mixed flocks of birds.
