Strigogyps is an early bird that lived during the Eocene and Oligocene period in Europe. Its legs were very long and adapted for running, indicating that it had a walking lifestyle like seriemas. Scientists even think that its wings weren’t capable of flying, or at least for long distances. Strigogyps was about the same size as a large chicken and several specimens have been discovered. Because the skull of Strigogyps has never been found, it is uncertain what its diet was. Some signs of a gizzard and crop indicates that it was mainly herbivorous, or at least omnivorous. Its habitat consisted of subtropical forests and open clearings.
A total of three species have been assigned to the genus of Strigogyps. S. dubius was described in 1908 and was thought to be a primitive owl. It was also thought to be closely related to the large South American terror birds. Nowadays, they are placed within the order of Cariamiformes, or Seriemas.
