We describe the nest and egg of the Black-headed Berryeater (Carpornis melanocephala), an Atlantic Forest endemic considered vulnerable to extinction. The nest was in a montane evergreen primary forest area in a tree fork 4.2 m above the ground. It was cup shaped and constructed mainly of leaves and stems, resembling a pile of aerial leaf litter. It held just one egg that was incubated solely by the female. The male was near the nest, and inspected it once while being observed.
