The White-banded Tyrannulet is a small bird of Andean forests. Its white eyebrow and two wing-bars stand out as it searches among leaves for small invertebrates.
It has a grey crown, a long white supercilium and a black line beside the eye. Two broad white wing-bars cross its brownish upperparts; the underside is greyish white with yellow on the lower belly.
It joins mixed-species flocks and moves through foliage, searching leaves for insects and other small invertebrates. Records include forest interior and edges and the ecotone with páramo.
