The trajectory was narrow enough that a small difference in direction could have produced a very different outcome.
The projectile was only a short distance from critical structures.
The X-ray explained the visible wound.
It did not yet tell the team enough about the three-dimensional damage.
Mercer requested advanced imaging.
A CT scan would provide a clearer view of the beak, nasal passages, surrounding bones, and the exact location of the metallic material.
The eagle was stabilized further before the scan.
The CT confirmed a localized fracture of the bony support beneath the upper bill. Several small fragments had shifted slightly around the entry tract. Soft tissue around the nasal cavity was swollen, and one passage was narrowed by inflammation and dried blood.
The projectile remained lodged close to the nasal structures.
The eye was spared.
The cranial cavity was spared.
The lower bill remained intact.
That combination gave the eagle a realistic chance.
The injury was still serious.
A beak is not simply an external ornament.
For a Bald Eagle, it is a primary feeding structure.
The bird uses it to tear flesh, manipulate food, maintain feathers, clean the feet, and perform normal grooming. Alignment matters. Strength matters. Sensation matters.
An eagle can have perfectly healthy wings and still be unable to survive if the beak no longer functions well enough to process food.
Mercer explained the problem to the rehabilitation staff.
“We are not just trying to close a wound,” she said. “We have to preserve a bill that can actually work.”
Blood samples were collected.
The team checked red blood cell parameters, hydration, kidney and liver function, and markers that might indicate infection or systemic stress.
A blood lead test was also included because the projectile appeared metallic and might contain lead.
The initial lead value was mildly elevated but not high enough to explain the bird’s clinical condition.
The primary emergency remained trauma.
The eagle was admitted to intensive care.
The wound was flushed carefully.
Pain control continued.
Because the injury was penetrating and contaminated, antimicrobial therapy was started under veterinary supervision.
The swollen nostril was monitored closely.
If inflammation became severe enough to compromise airflow through the upper airway, the case could deteriorate quickly.
Nutrition was another immediate concern.
The eagle could not safely tear normal food.
Trying to force the damaged beak to work could destabilize the fracture.
For the first stage of treatment, nutritional support would have to be provided in a way that reduced stress on the bill.
The staff prepared for assisted feeding.
Mercer also consulted with a colleague experienced in avian reconstructive procedures.
The decision was made to surgically explore the injury after the bird had been stabilized.
The goals were clear.
Remove the projectile if doing so could be accomplished without creating greater damage.
Clean the wound tract.
Remove nonviable tissue.
Restore the upper beak as close to normal alignment as possible.
Preserve airflow through both nostrils.
Protect the underlying structures while healing occurred.
The surgery was scheduled for the following morning.
That first night was difficult.
The eagle remained awake, but it was uncomfortable.
The head stayed low.
The bird occasionally tried to rub the beak against the towels and had to be prevented from doing so.
It did not eat independently.
Fluids continued.
The staff minimized handling.
Every hour, someone checked the bird’s breathing from outside the enclosure.
The injured nostril remained partly obstructed but functional.
No sudden respiratory crisis developed.
The eagle made it through the night.
By morning, hydration had improved enough for anesthesia.
The surgical team prepared carefully.
The beak injury was small from the outside but complicated beneath the surface. Feathers were kept clear of the surgical field. Imaging was reviewed again before the procedure began.
Once the eagle was anesthetized, Mercer explored the wound tract.
The projectile was accessible.
It had damaged the bony support beneath the upper beak but had not fragmented extensively.
The surrounding tissue showed bruising and contamination.
The projectile was removed.
The wound was irrigated thoroughly.
Loose damaged material was addressed conservatively so that as much healthy structure as possible could be preserved.
Then came the challenge of alignment.
The upper bill had shifted enough that it no longer met the lower bill normally.
Mercer and the surgical team realigned the damaged structure and applied a lightweight temporary support using veterinary materials suitable for stabilizing the beak while minimizing excess weight.
The objective was functional alignment, not cosmetic perfection.
A Bald Eagle does not need a flawless-looking bill.
It needs a bill strong enough to tear food and aligned well enough to close properly.
The team repeatedly checked the relationship between upper and lower beak during the procedure.
The nostrils remained open.
The tongue moved normally.
The eye remained unaffected.
When the eagle recovered from anesthesia, the temporary support held.
That was the first major success.
It was not the end of the case.
The following seventy-two hours would determine whether swelling, infection, tissue compromise, or instability developed.
The eagle returned to intensive care.
For the remainder of the first day, it remained quiet.
The beak was visibly swollen.
The white feathers around the face carried dried staining from the original injury despite careful cleaning.
The bird showed little interest in eating.
Nutritional support continued.
Staff watched for signs of worsening pain, respiratory difficulty, tissue discoloration, or displacement of the repair.
Nothing changed dramatically overnight.
By the second morning, the eagle was brighter.
It raised its head when staff entered.
The feet moved more forcefully.
The bird tried to turn away during examination.
The beak itself remained swollen but stable.
Mercer considered that encouraging.
The third day produced an even more meaningful sign.
During a routine check, the eagle tried to bite the towel.
The motion was limited.
The staff member pulled back immediately to avoid stressing the repair.
But everyone in the room understood what they had just seen.
The beak was beginning to behave like a beak again instead of simply remaining an injury.
Mercer smiled briefly.
“That is the first time I am happy to see this bird try to bite someone,” she said.
The eagle still was not ready to eat normally.
Soft food was introduced cautiously.
Small pieces of fish were offered in a way that allowed the bird to take them without tearing.
At first, the eagle had difficulty.
The upper bill did not grip with full confidence.
The bird picked up a piece, adjusted it several times and dropped it.
A second attempt was more successful.
The food was swallowed.
That small act became the first true functional test of the repair.
For this patient, rehabilitation did not begin in a flight aviary.
It began over a piece of fish.
During the first week, the wound remained clean.
Swelling gradually decreased.
The nostril became more open as inflammation resolved.
The eagle’s appetite improved, although food still had to be prepared in manageable portions.
It was not yet allowed to pull aggressively against tough tissue.
The temporary beak support remained in place.
The eagle became increasingly defensive around staff.
