Jackie Eagle Avian Influenza Findings: Trending Necropsy Results and Health Report

The final necropsy report on Jackie, the famed Big Bear Valley bald eagle, reveals that Highly Pathogenic Avian Influenza (HPAI) was the primary underlying cause of her decline and death. Wildlife pathologists from the San Diego Zoo Wildlife Alliance, along with the California Department of Fish and Wildlife (CDFW) and the Ojai Raptor Center, confirmed that the viral infection triggered a chain of severe, interconnected medical conditions that ultimately overwhelmed her system.

Key Findings from Jackie’s Final Necropsy Report

• Primary Cause of Decline: Diagnostic testing confirmed Highly Pathogenic Avian Influenza (HPAI / bird flu) as the chief disease process driving her rapid physical deterioration.

• Gastrointestinal Ulcers and Anemia: The virus contributed to chronic, damaging lesions in her ventriculus (gizzard), causing severe internal ulceration, persistent blood loss, and profound anemia.

• Secondary Systemic Infections: The ulcerated stomach lining allowed harmful bacteria to enter her bloodstream, sparking a secondary bacterial infection accompanied by severe inflammation and blood clotting in her heart and major blood vessels.

• Toxicology and Heavy Metals: While trace amounts of anticoagulant rodenticide were detected, officials confirmed there was no evidence of uncontrolled fatal hemorrhaging typical of rat poison toxicity. Lead levels and heavy metals were within normal thresholds, and she tested negative for West Nile Virus.
