Breeding
Nest
Both build the nest out of mud and sticks on branches, forks or posts. It is rounded and resembles a motobike helmet with a door ajar. Nests are used for the breeding season and then reused by other species (finches, swallows, etc.)

Every year we find Shiny cowbird chicks being fed by foster parents. This video shows the Rufous Hornero, but other species have also been recorded photographically at Costanera.
