Male bearded vultures build nests with branches and animal remains and have several within a single territory, rotating between them, yearly.
Breeding pairs of bearded vultures have several nests within a single territory, and rotate between them on a yearly basis.
Males tend to more actively build nests and defend territories, while females allocate more time and energy tending to the nest. However, both males and females display territorial behavior around the nest against other bearded vultures and heterospecifics.
Beraded vultures will construct large nests, averaging 1-meter in diameter, composed of branches and lined with animal remains such as skin and wool, as well as dung and occasionally also rubbish. Nests are located on remote overhung cliff ledges or in caves and will be re-used over the years.
