Commentaires

An adult eating pieces of a mollusc that it had previously broken by droping it while flying. The bird was clearly acting on purpose, in a manner similar to what Bearded Vultures do to crack bones. The mollusc was drop from a height of about 10 m. Elevation: 0 m. Date added to IBC: June 22, 2016.
