What is it?

The Eurasian Eagle-Owl (Bubo bubo) is a powerful nocturnal raptor but remains highly vulnerable to hazards created by humans. Trauma encompasses all physical injuries: collisions with vehicles, windows or cables, falls, impacts with wire mesh, or territorial fights. Electrocution occurs when a bird lands on an electrical post or poorly insulated medium-voltage power line and current passes through its body, often between two contact points such as both wings or a wing and a leg. These accidents are among the leading causes of mortality and hospitalization in raptors brought to wildlife rescue centers.

Key point

Life-threatening emergency: any raptor victim of trauma or electrocution must be treated as quickly as possible by a veterinarian or wildlife rescue center, without prolonged handling by untrained people.

Commonly observed signs

These signs are neither exhaustive nor specific. Only a veterinarian can establish a diagnosis.

Related signs — each one links to its page:

Signs depend on the severity and type of accident. An abnormally drooping wing may be observed, limping, inability to fly or stand, swelling of a leg or wing, visible wounds or an area of burned and blackened skin (typical of electrocution).

The bird may be depressed, prostrate, with half-closed eyes and ruffled feathers.

In severe cases: convulsions, trembling, paralysis of a limb, loss of sight, bleeding from the beak or nostrils, or the bird remaining lying down unable to get up.

Electric shock can also cause immediate cardiac arrest with no visible external injury.

When to consult without delay

This list does not replace veterinary advice. It gathers situations that justify a prompt consultation.

Causes and risk factors

Collision with a vehicle, window, wire mesh or cable; fall from a nest or perch; electrocution from simultaneous contact with two conductive elements on a medium-voltage power line; fighting with another individual or different species; illegal shooting or trapping.

Inexperienced young birds in the fledging phase, areas with uninsulated electrical infrastructure, proximity to busy roads, presence of wire mesh or barbed wire in hunting territory, period of juvenile dispersal after independence.

Diagnosis and care

Diagnosis is the veterinarian's responsibility, based on clinical examination and laboratory tests. Care is decided case by case.

1

The veterinarian examines the bird with great care, as an injured raptor can defend itself with its powerful talons. A shock assessment is performed, fractures are checked by palpation, and confirmed by X-ray if needed. The skin is inspected for burns typical of electrocution, usually found under the wings or on the legs. A neurological examination and vision check are carried out if the bird has suffered a head injury. Blood work may be useful to evaluate the bird's general condition before any possible anesthesia.

Treatment

Treatment depends on the injuries: emergency stabilization for shock, oxygen therapy, fluids, pain management with analgesics suitable for birds, antibiotics if there is an open wound or burn to prevent infection. Fractures may require external splinting or orthopedic surgery. Electrocution burns require specific local care and monitoring for tissue necrosis, which may develop later. Functional rehabilitation is often necessary before any attempt to release the bird.

Treatment depends on the cause and the animal's condition: it must be determined by a veterinarian. No self-medication.

Prevention

Insulation of hazardous power lines by specialized contractors, installation of anti-electrocution devices on poles, placement of decals or visual strips on large glass windows, removal of unnecessary wire mesh from areas frequented by raptors, prompt reporting of any injured bird to a wildlife rescue center or veterinarian.

Possible complications

Delayed skin or tissue necrosis following electrocution, amputation of a wing or leg, wound infection, permanent loss of flight ability, blindness, neurological aftereffects, delayed death from cardiac arrest even after an apparently tolerated shock.

When to see a veterinarian

The bird cannot stand or fly.

One wing hangs abnormally or appears deformed.

Presence of blood, open wound, or blackened and burned skin.

The bird remains still, eyes half-closed, with no normal reaction.

Convulsions, trembling, or paralysis of a limb.

Any raptor found on the ground unable to fly must be treated as an emergency.

Prognosis

The prognosis varies widely depending on the nature and severity of the injuries. A minor trauma without fracture may allow the bird to return to the wild after a few weeks of care. A complex wing fracture, extensive electrocution burn, or severe neurological damage greatly compromises the chances of release and may result in lifelong captive care or euthanasia if suffering is too severe.

Frequently asked questions

What to do if you find an injured Eagle Owl by the roadside? If you find an injured Eagle Owl (or any bird of prey) on the roadside, here are the recommended steps: 1. **Ensure your safety first** – Stay alert to traffic and keep a safe distance from the bird. 2. **Minimize stress** – Avoid sudden movements or loud noises. The bird may be frightened and could injure itself further. 3. **Contact wildlife professionals** – Call your local wildlife rehabilitation center, animal control, or an emergency veterinary clinic specializing in wild animals. They have the expertise and proper equipment to handle birds of prey safely. 4. **If you must move the bird** – Only do this if it's in immediate danger (e.g., in the middle of the road). Use a blanket or cloth to gently cover and contain it, then place it in a well-ventilated box away from noise and pets. 5. **Provide temporary shelter** – Keep the bird in a warm, quiet, dark place until professionals arrive. 6. **Do not attempt medical treatment** – Birds of prey can be aggressive when injured, and improper handling may cause additional harm. 7. **Wash your hands** – After any contact, wash thoroughly for hygiene and safety. Time is critical for injured wildlife, so prompt professional help offers the best chance of recovery.

Protect it by covering it with a thick cloth to limit stress and injuries from its talons, place it in a ventilated box and immediately contact a wildlife rescue center or a veterinarian. Avoid giving it anything to drink or eat.

Does electrocution always leave visible marks?

No. An electrical shock can be fatal without leaving any visible external burn, particularly in the case of immediate cardiac arrest. The typical burns, when they do occur, are often found under the wings or at the level of the legs.

Can a Great Eagle Owl with a broken wing ever fly again?

It depends on the type of fracture. Some simple fractures that are well treated allow for complete recovery, but complex fractures near the joints often permanently compromise flight capacity.

Are these accidents frequent in this species?

Yes, collisions and electrocution are among the leading causes of mortality and admission to care facilities for large nocturnal raptors such as the Eagle Owl, particularly among young birds in the dispersal phase.
