These birds forage for insects in the lower forest layers. Outside the breeding season, they often join mixed-species flocks. During nesting, the pair builds the nest, incubates the eggs, and feeds the chicks. Both parents share duties. In some cases, females have been observed performing distraction displays to protect their nests from intruders.

They inhabit forests, secondary growth, and gallery woodlands.

We observed nests in Quebrangulo, Alagoas (80 nests) and Arcos, Minas Gerais (7 nests).

In Quebrangulo, nests are found year-round, with peaks in October and November. In Arcos, most nests are observed between September and November.

The nest is a small hanging cup, placed low in vegetation, usually 0.5 to 1.5 m off the ground. It is built in the forks of branches or in grass clumps, using materials like black fungal threads, mosses, lichens, spider egg sacs, and fine plant fibres. The construction and materials vary, with some nests appearing darker or lighter depending on the materials used.
