The outside walls of their nests are decorated with lichens, fragments of leaves and branches, which sometimes extend from the bottom of the nest, camouflaging it with the environment.

In the UFRA area: This species of bird is little frequent in the surveys done, as it was seen only 11 times. It had a medium spatial distribution, being found in exotic woods, wetlands with riparian forests, in the restored native forests, in mixed forests in regeneration, and in native forests.
