Jackie the bald eagle’s final cause of death revealed

The Ojai Raptor Center released the final necropsy results for Jackie, an internet-famous bald eagle mother who was in their care this summer. Jackie was brought into the bird rehabilitation center weak and dehydrated following an altercation with another eagle in July. 

Officially designated as Patient 26-519, Jackie’s necropsy revealed a “complex and unusual disease process involving severe, chronic inflammation and ulceration of the stomach, persistent internal bleeding, anemia and secondary bacterial sepsis.” She was also diagnosed with Highly Pathogenic Avian Influenza (HPAI) commonly called bird flu, which was behind severe stomach ulceration. Raptors (eagles, hawks, falcons, owls, etc.) are highly susceptible to the virus 

All of these medical complications developed over time and ultimately contributed to her death on August 10.

“These findings have helped connect many of the pieces we were seeing throughout her hospitalization and provided a better understanding of the challenges she faced,” the Ojai Raptor Center wrote. “We are grateful to the many veterinary specialists, laboratories, wildlife agencies and partner organizations who worked alongside our team to understand her illness and provide her with the best possible care. Caring for her was an extraordinary privilege for our entire team.”

The full report can be read in Jackie’s veterinary medical journal. The necropsy was preformed by veterinary pathologists at the San Diego Zoo Wildlife Alliance.

Friends of Big Bear Valley (FOBBV), the non-profit organization that runs the live cameras where viewers from all over the world watched Jackie and her partner Shadow, said that they will follow up with their thoughts once their team has had time to process the report.

“The story of the Big Bear bald eagle reflects the powerful connection people feel to these iconic birds,” California Department of Fish and Wildlife Director Meghan Hertel added. “We’re grateful to everyone who cared for her and worked to support her well-being.  Understanding the results of these tests is an important part of learning from this case and can help inform the care and treatment of other eagles and wildlife in the future.”

Jackie’s story

Jackie was born, raised, and lived in Big Bear Valley in Southern California. Prior to the 2011-2012 nesting season, no bald eagle chicks were known to have ever hatched in Big Bear Valley. Then came Jackie, named after a forest ranger and born to parents Ricky and Lucy in 2012. 

During the 2016-2017 nesting season, Jackie took over a nest where Friends of Big Bear Valley (FOBBV) had a camera stationed. In 2018, she had two chicks named Stormy and Big Bear Baby (or BBB) with her first mate, Mr. B. 

Her long-time partner Shadow entered the picture in summer 2018. He showed up at the nest and would not leave. FOBBV called the new male Shadow because he appeared so determined to stay in the nest, and the team initially believed he was one of Jackie’s siblings, also named Shadow. The eagle’s plumage indicated he was one year older than the other Shadow and not Jackie’s sibling, but the name stuck. 

Shadow continued to hold his ground and Mr. B gave up and eventually left. Jackie then accepted Shadow as her new mate.

Wildlife cameras documented Jackie and Shadow’s life together, offering viewers a direct look into the brutality and beauty of nature. The pair successfully raised chicks in 2019 (Cookie and Simba) and 2022 (Spirit). The pair’s eggs failed to hatch in 2023 and 2024. In 2025, Jackie laid three eggs that all hatched in early March. However, a strong snowstorm dumped up to two feet of snow and battered the nest with strong wind and only two of the chicks (Sunny and Gizmo) survived.  

In January, Jackie laid two eggs in the nest, but ravens destroyed them. She later laid two more eggs that hatched in April and named Luna and Sandy. The name Sandy is in honor of FOBBV’s former executive director Sandy Steers who died from cancer in February. 

Jackie’s injury and death

On July 17, Jackie was found injured on the ground near Dana Point Park, California. Cell phone video from a witness confirmed that she had an altercation with two other subadult eagles. She successfully fended off the other eagles by turning over and using her talons, but could not fly far away. 

She was transferred to the Ojai Raptor Center, where she was diagnosed with severe anemia. Her anemia worsened during the first week of August, the Ojai Raptor Center said that she was in unstable condition on August 9. Her packed cell volume (PCV) fell below percent, before rising to nine percent.

Jackie died early in the morning on August 10. The necropsy did not reveal a single cause of death, and instead pointed to several factors including severe anemia, blood clots in her wing and one kidney, and liver and lung abnormalities.

Jackie’s resilience inspired millions of people around the world. To honor her memory, FOBBV accepts donations to support its conservation efforts in the area.  Supporters can also donate to Ojai Raptor Center’s Bald Eagle Recovery Campaign.
