An avian Modified Glasgow Coma Scale as a prognostic indicator in raptors with head trauma.

Objective: To develop a Modified Glasgow Coma Scale (MGCS) for use in raptors presenting with head trauma and assess the agreement of the MGCS scores between examiners with varying backgrounds, and to assess the prognostic value of the avian MGCS in raptors with head trauma.

Animals: 156 native raptorial species.

Methods: All raptors received an MGCS assessment within 8 hours of their presentation, between January 1, 2018, and December 31, 2019.
