Big Bear bald eagle Jackie shows improvement, remains stable but critical in ICU at recovery center

BIG BEAR LAKE, Calif. -- Big Bear bald eagle Jackie remains stable but critical as she is treated in intensive care at the Ojai Raptor Center, vet teams shared in an update on Monday.

Jackie, one half of the beloved bald eagle couple in Big Bear, has been receiving care at the center since she was discovered on the ground near Big Bear Lake after a fight with two younger eagles. She was discovered anemic with inflammation affecting her kidneys, which is why teams think she was vulnerable to the eagle attack.

In Monday's update, the Ojai Raptor Center said the team is still working to determine the underlying cause of Jackie's illness as she receives several prophylactic treatments to help support her body.

While Jackie began showing encouraging improvement following a blood transfusion last week, she experienced a setback when her blood values declined on Saturday, the vet team said.

Since then, she has begun improving again.

In a new video posted to social media, the Ojai Raptor Center showed how Jackie has improved from being fed while restrained to eating on her own with more energy and alertness.

They noted that she has become much more feisty during her feedings.

The video also features footage from Jackie's blood transfusion and her later perking up and vocalising.

The team said one of the most encouraging signs of recovery is her packed cell volume (PCV), which measures the percentage of red blood cells in her bloodstream.

"Her PCV has increased from 8% before the weekend to 16% today (7/27). While this remains below normal, it is an encouraging improvement, and we will continue to monitor her bloodwork daily as we keep a close eye on her progress," the vet team wrote.

Despite the around-the-clock work, the experienced wildlife veterinarians still do not have a definite diagnosis.
