The white-browed chat-tyrant is a small bird about 13 centimeters long. It has a gray back, a light belly and a bright white stripe above the eyes, which helps distinguish this species from other tyrants.
The white-browed chat-tyrant differs from related species by its bright white eyebrow and gray plumage. It is beneficial for nature because it eats many insects and helps maintain balance in the mountain ecosystems of the Andes.
