A common raven was admitted to our clinic on May 17, 2024 presenting with a broken leg. Weighing in at 1.05 kg, this weight is typical for a juvenile raven. Upon admission, the raven was highly alert, and its right leg was notably swollen. A comprehensive initial examination was conducted, and the raven received anti-inflammatory medication as well as additional medication to alleviate discomfort in the affected leg.

On May 22, 2024, the raven underwent an x-ray to assess the condition of the broken leg. Once our veterinarian examined the bird, it was revealed that the raven was not properly bearing weight on its right leg, and its ankle was swollen. Because of this, the bird's medication regimen was extended to address the ongoing inflammation and discomfort.
Throughout the rehabilitation process, the raven's behaviour and physical condition were closely monitored. After a month in care, the raven was observed using both legs equally well, demonstrating the ability to grasp and hop. Despite mild inflammation and a slight bow at the foot joint, the raven's mobility had not been severely affected. The raven was seen moving from perch to perch and holding twigs while flying. This behaviour indicated satisfactory flight capabilities, appetite, and mentation, despite a slight limp.

The raven initially housed in our isolation trailer and later moved to a larger enclosure with ample enrichment toys, natural sunlight, and a natural breeze. This environment is designed to facilitate physical and mental stimulation, promoting overall recovery. After another week, the team conducted thorough behavioural and physical examinations to ensure the raven could bear weight and use its right leg effectively.
Following 45 days of care and rehabilitation, the common raven was deemed fit for release. On July 1, 2024, the raven was then successfully released back into its established habitat. This successful release underscores the efficacy of our comprehensive rehabilitation protocols, which include medical treatment, environmental enrichment, and continuous monitoring to ensure optimal recovery.
