Recognising Illness, Weakness, Injury & Distress in Wild Birds

Knowing when a bird needs help

Wild birds can be remarkably good at hiding signs of illness and injury. In the wild, appearing weak or vulnerable can make an animal more susceptible to predators, so obvious symptoms may only become apparent once a bird is significantly unwell.

At CapesWildlifeRescue, we encourage members of the public to familiarise themselves with the warning signs that a bird may need assistance.

Recognising these signs early can help ensure that sick or injured birds receive appropriate assessment and care.

However, not every bird seen on the ground or behaving unusually needs rescuing. Understanding the circumstances and observing safely are important first steps.

1. Signs of Illness or Weakness

A bird that is unwell may behave differently from others of its species. Changes in posture, activity, appetite and responsiveness can all be important clues.

Potential warning signs include:

• Persistent fluffed-up feathers: The bird appears unusually puffed up and inactive, particularly when accompanied by weakness or reduced responsiveness.

• Lethargy: The bird remains unusually still, has little energy or does not respond appropriately to its surroundings.

• Reduced appetite: The bird appears unable or unwilling to eat, or repeatedly attempts to feed without success.

• Abnormal posture: The bird sits unusually low, struggles to remain upright or holds its body in an abnormal position.

• Weight loss or poor body condition: The breastbone appears prominent, or the bird looks noticeably thin and weak.

• Eye abnormalities: The eyes remain closed, appear swollen, or have unusual discharge.

• Discharge from the nostrils or mouth: Wetness, mucus or other abnormal material may indicate a health problem.

• Changes in droppings: A persistent change in the appearance or consistency of droppings may be associated with illness, although droppings vary naturally with diet and hydration.

• Reduced awareness: The bird allows unusually close approach, appears confused or does not respond normally to movement nearby.

These signs are not specific to one disease. A bird displaying one or more of them may need professional assessment, particularly if the changes are persistent or severe.

2. Signs of Injury

Some injuries are obvious, while others can be concealed beneath feathers.

Look for:

• Visible bleeding or open wounds.

• A wing hanging lower than the other.

• Inability to fly or repeated unsuccessful attempts to take off.

• Difficulty standing, walking or perching.

• A leg held in an abnormal position.

• Swelling around a limb or joint.

• Feathers that are heavily damaged, displaced or contaminated with blood.

• Obvious impact injuries following a collision.

• Fishing line, netting or other material caught around the body or limbs.

A bird may still be able to move despite having a significant injury. Being able to walk, flap its wings or briefly fly does not necessarily mean that it is unharmed.

Do not attempt to straighten a limb, manipulate a suspected fracture or remove embedded objects. These actions can cause additional pain or damage.

3. Recognising Breathing Difficulties

Breathing problems can be particularly serious in birds and should not be ignored.

Warning signs may include:

• Open-mouth breathing when the bird is resting in a cool, quiet environment.

• Pronounced movement of the tail with each breath.

• Noticeable effort when breathing.

• Wheezing, clicking or other abnormal respiratory sounds.

• Discharge around the nostrils.

• Stretching the neck or repeatedly changing posture in an apparent attempt to breathe more comfortably.

Birds may breathe with their beaks open during heat stress or following exertion, so context matters. However, persistent or laboured breathing, especially when accompanied by weakness, requires urgent assessment.

If a bird is struggling to breathe, avoid handling it unnecessarily. Contact an appropriate wildlife rescue or veterinary practice promptly.

4. Neurological Signs and Abnormal Behaviour

Changes in coordination or awareness may indicate injury, illness, poisoning or another serious problem.

Warning signs include:

• Loss of balance or repeatedly falling over.

• Walking in circles.

• Head tilt or an unusual head position.

• Tremors, seizures or uncontrolled movements.

• Inability to perch or remain upright.

• Appearing disorientated or unaware of surroundings.

• Unusual weakness or reduced responsiveness.

A bird displaying these signs should be assessed urgently.

Do not attempt to give food, water or medication to a bird that is poorly coordinated, having seizures or unable to swallow normally. There is a risk of further injury or aspiration.

5. Birds That Have Been Attacked by Cats or Dogs

Birds caught by cats or bitten by dogs can suffer serious injuries, even when no obvious wound is visible.

Small puncture wounds may be hidden beneath feathers, and bacteria introduced during an attack can lead to serious infection.

If you find a bird following an attack:

1. Contact a wildlife rescue or veterinary practice promptly.

2. Explain clearly that a cat or dog has caught or bitten the bird.

3. Avoid unnecessary handling or repeated examination.

4. Follow advice on safe containment and transport.

Do not assume the bird is unharmed simply because it can still stand, walk or fly.

6. Birds That Have Collided with Windows

Window collisions can cause injuries ranging from temporary disorientation to serious head trauma, fractures and internal injuries.

A bird may initially remain still after an impact. However, apparent recovery does not always mean that no injury has occurred.

If you find a bird following a collision:

• Observe it from a safe distance.

• Check for visible injuries or difficulty standing.

• Keep people and pets away.

• Seek advice if it remains dazed, cannot stand normally or shows any other warning signs.

If the bird has obvious injuries, abnormal coordination or persistent weakness, arrange prompt professional assessment.

Do not repeatedly handle or release a bird to test whether it can fly.

7. Is the Bird Actually in Distress?

Some behaviours that look concerning are normal for particular species or stages of development.

For example:

• Fledglings on the ground: Young birds often leave the nest before they can fly confidently. Their parents may continue feeding them nearby.

• Birds resting quietly: A bird may simply be resting, particularly after feeding or during periods of reduced activity.

• Seasonal behaviour: Breeding, moulting and migration can affect a bird's appearance and behaviour.

• Temporary open-mouth breathing: This can occur following exertion or in hot weather, although persistent breathing difficulties remain concerning.

The important distinction is whether the bird is behaving appropriately for its species and circumstances.

If it is alert, coordinated and showing no signs of injury, observation from a safe distance may be appropriate. If it is weak, injured, disorientated or struggling to breathe, seek help.

When in doubt, contact a wildlife rescue for advice before intervening.

8. What Should You Do If You Find a Bird That Needs Help?

Step 1: Observe safely

Avoid chasing or repeatedly approaching the bird. Look for obvious signs of injury, weakness or distress without putting yourself at risk.

Step 2: Contact a wildlife rescue

Contact CapesWildlifeRescue and explain what you have found. Provide the species if known, the location, the circumstances and the signs you have observed.

Photographs or videos can be useful where they can be obtained safely without disturbing the bird.

Step 3: Follow the advice provided

Depending on the bird's condition, you may be advised to leave it undisturbed, monitor it from a distance or contain it safely.

Do not attempt to handle birds of prey, large waterbirds or other potentially dangerous species without appropriate guidance.

Step 4: Avoid feeding or medicating

Do not force-feed the bird, pour water into its beak or administer medication without appropriate professional advice.

Incorrect feeding or treatment can worsen its condition.

Step 5: Arrange admission if necessary

If the bird requires admission to CapesWildlifeRescue, our team will agree an arrival time and provide the necessary site details.

All admissions must be authorised in advance. Please do not arrive at our site without an agreed admission and arrival time.

9. When Is Urgent Help Needed?

Seek prompt assistance if a bird:

• Is struggling to breathe.

• Has uncontrolled bleeding or a serious wound.

• Cannot stand or remain upright.

• Has seizures or severe loss of coordination.

• Has been caught by a cat or bitten by a dog.

• Has an obvious fracture or significant injury.

• Is severely weak, unresponsive or deteriorating.

• Is trapped in a dangerous situation.

If you cannot reach our team and the bird appears critically unwell, contact an appropriate veterinary practice or another wildlife rescue rather than delaying necessary care.
