Identification and description:
The Zimmerius bolivianus, or Bolivian Tyrannulet, is a small passerine bird belonging to the Tyrannidae family. It is primarily found in the humid montane forests of the Andean region, particularly in Bolivia and Peru. This bird is characterized by its olive-green plumage on the back and yellow on the belly, with slightly darker wings. It is often seen feeding on insects and small fruits, moving nimbly among the branches. Although discreet, its melodious and repetitive song often reveals its presence. The Bolivian Tyrannulet plays an important role in the ecosystem by contributing to seed dispersal and insect population control.

Photography tips:
To photograph the Bolivian Tyrannulet, it is advisable to use a 400mm lens or longer to capture detailed images without disturbing the bird. Look for areas where the bird is active, such as cloud forests, and be patient. Listen for its distinctive song to locate its position. The natural light of the morning or afternoon is ideal for capturing vivid and natural colors. Use a tripod to stabilize your camera and avoid blurring.
