A widespread bacterial infection was identified as the most likely cause of death of Sawaga-Dalwangan, a Philippine eagle that was rescued first in Malaybalay City, Bukidnon, based on examination results released by the Philippine Eagle Foundation (PEF).

PEF said the examination of tissue samples taken from the eagle’s liver, heart, and spleen found signs of a serious bacterial infection that had spread throughout its body.

Bacteria were detected in its liver, while inflammation and tissue damage were observed in several organs, including the liver and heart.

“Together with the findings from her medical examination and necropsy, the results show that a widespread bacterial infection was the most likely cause of her death,” PEF said.

PEF said the tissue changes also suggested that the infection may have been developing over a subacute to chronic period, potentially beginning weeks before its death.

PEF explained that Sawaga-Dalwangan was rescued on July 3, 2026, in a compromised condition as it was dehydrated, lethargic, and heavily soiled, with external wounds, maggot infestation, and injuries associated with airgun pellets.

PEF said these conditions may have increased her susceptibility to a secondary bacterial infection.

Despite its condition, Sawaga-Dalwangan showed encouraging signs of recovery during treatment. Its wounds began to heal, its hydration and appetite improved, and it displayed normal behavior, eventually.

However, examination showed later that a serious infection remained in its body.

PEF said Sawaga-Dalwangan suddenly developed generalized seizures on July 18 and died shortly afterward despite receiving immediate emergency treatment.

“We are sharing these findings because Sawaga-Dalwangan’s story deserves an ending based on scientific evidence, and because everyone who followed her journey and hoped for her recovery deserves to understand what happened,” PEF said.

“She was fought for. She was cared for. And she will not be forgotten,” PEF added.
