Essential Background

The Full Story

Keywords related to "Big Bear bald eagles Jackie" are trending due to the recent public release of her final necropsy findings, which definitively identified highly pathogenic avian influenza (HPAI), or bird flu, as the primary cause of her death. Jackie passed away on August 10, 2026, after weeks of intensive care at the Ojai Raptor Center following her rescue in July after an altercation with other eagles. The necropsy, performed by veterinary pathologists at the San Diego Zoo Wildlife Alliance, revealed that the bird flu led to a severe and unusual medical condition, including stomach ulceration, persistent internal bleeding, anemia, and a secondary bacterial infection. While an anticoagulant rodenticide was detected in her liver, it was not deemed the primary cause of her illness or death.

Why It Matters

The revelation of Jackie's cause of death is significant to her vast number of followers who had been mourning her passing and seeking answers regarding her mysterious illness. Her story highlighted the powerful connection people feel to iconic wildlife and underscored the challenges faced by wild bird populations, including the threat of avian influenza. The detailed findings contribute to a better understanding of how HPAI can affect raptors, even if presenting in uncommon ways, and reinforces the importance of wildlife health monitoring and conservation efforts. Her remains were cremated by the U.S. Fish and Wildlife Service to prevent further spread of the bird flu and will be sent to the National Eagle Repository to support tribal cultural traditions.
