Staphylococcal Infection in Macaws
- Staphylococcal infections in macaws usually involve the skin or feet, especially pressure sores on the footpad called pododermatitis or bumblefoot.
- These infections often start after skin damage from poor perch surfaces, pressure points, dirty housing, or self-trauma rather than appearing out of nowhere.
- Common signs include foot swelling, scabs, limping, holding one foot up, redness, discharge, feather loss over irritated skin, and reduced activity or appetite.
- Your vet usually needs an exam plus cytology or bacterial culture to confirm the infection and choose the most appropriate antibiotic.
- Mild cases may improve with wound care, bandaging, perch changes, and medication, while advanced cases can need radiographs, debridement, anesthesia, and repeat bandage changes.
What Is Staphylococcal Infection in Macaws?
Staphylococcal infection in macaws is a bacterial infection caused by Staphylococcus species, most often affecting the skin, feather follicles, wounds, or footpads. In pet birds, staphylococci are commonly linked with dermatologic disease and are often found in lesions of pododermatitis, also called bumblefoot. In macaws, this matters because their size and weight put extra pressure on the feet when perch setup is not ideal.
These bacteria are common in the environment, and some staphylococcal species may be present on birds without causing disease. Infection usually develops when the skin barrier is damaged or when husbandry problems create ongoing irritation. That is why a macaw with a staph infection often has an underlying issue too, such as pressure sores, trauma, poor sanitation, obesity, nutritional imbalance, or chronic stress.
Some infections stay local and cause swelling, scabs, or abscesses. Others can spread deeper into tendons, joints, or bone, especially when foot lesions are ignored. Because birds tend to hide illness, even a small sore can become serious faster than many pet parents expect.
Symptoms of Staphylococcal Infection in Macaws
- Red, irritated, or thickened skin on the feet
- Firm swelling on the bottom of one or both feet
- Scab, ulcer, or pressure sore on the footpad
- Holding one foot up, limping, or reluctance to perch
- Pain when climbing or stepping onto perches
- Discharge, draining tract, or foul-smelling wound
- Abscess-like lump in the foot or skin
- Feather loss or over-preening around an irritated area
- Reduced appetite, fluffed posture, or lower activity
- Blackened tissue, marked swelling, or inability to bear weight
Mild redness or a small sore can be the first sign, but macaws often keep using the foot until pain becomes significant. See your vet promptly if your bird is favoring a foot, has a scab or swelling, or seems less willing to climb. See your vet immediately if there is discharge, a growing lump, severe pain, bleeding, black tissue, or your macaw is weak, not eating, or sitting fluffed at the bottom of the enclosure.
What Causes Staphylococcal Infection in Macaws?
Most staphylococcal infections in macaws are secondary infections. That means the bacteria take advantage of damaged skin or stressed tissue. A very common setup is pressure injury on the footpad from smooth dowel perches, perches that are all the same diameter, rough or abrasive surfaces, or hard flooring without padded rest areas. Once the skin is irritated or cracked, bacteria can move in.
Other contributors include dirty cages, wet or feces-soiled surfaces, splinters, minor cuts, burns, self-trauma from over-grooming, and obesity that increases pressure on the feet. Inappropriate diet and low vitamin A status can also weaken skin and mucosal health, making infection more likely. Birds with chronic illness or poor body condition may have a harder time fighting off bacteria.
In some macaws, the visible infection is only part of the story. Your vet may also look for behavior, nutrition, perch design, and mobility issues that set the stage for recurrence. Treating the bacteria without correcting those factors can lead to repeat infections.
How Is Staphylococcal Infection in Macaws Diagnosed?
Diagnosis starts with a careful avian exam and a close look at the skin and feet. Your vet will ask about perch materials, cage hygiene, diet, activity level, recent trauma, and how long the lesion has been present. In birds, appearance alone is not enough to confirm a staph infection because several bacterial problems can look similar.
Your vet may collect a sample for cytology or bacterial culture and sensitivity testing. Culture is especially helpful because staphylococci can be contaminants or normal surface bacteria, so the lab result has to match the lesion and exam findings. Sensitivity testing helps your vet choose an antibiotic that is more likely to work and avoid trial-and-error treatment.
If the foot is very swollen, painful, or chronic, your vet may recommend radiographs to check whether the infection has reached deeper tissues, tendons, joints, or bone. In a sick macaw, additional testing such as bloodwork may be used to look for systemic illness, inflammation, or problems that could affect healing.

Questions to Ask Your Vet About Staphylococcal Infection in Macaws
Bring these questions to your vet appointment to get the most out of your visit.
- You can ask your vet whether this looks like a superficial skin infection, pododermatitis, or a deeper abscess.
- You can ask your vet if a culture and sensitivity test would help choose the most appropriate antibiotic for your macaw.
- You can ask your vet whether radiographs are needed to check for tendon, joint, or bone involvement.
- You can ask your vet which perch changes are most important for your macaw's size, grip, and foot health.
- You can ask your vet how often bandages should be changed and what warning signs mean the wrap is too tight or slipping.
- You can ask your vet what pain-control options are appropriate and how to monitor appetite and droppings during treatment.
- You can ask your vet how to clean the enclosure and perches safely while your macaw is healing.
- You can ask your vet what factors may have caused the infection in the first place so recurrence is less likely.
How to Prevent Staphylococcal Infection in Macaws
Prevention focuses on protecting the skin and feet. Offer multiple perch diameters and textures, and avoid making smooth dowel perches the only option. Macaws do best when they can shift pressure points throughout the day. Flat resting platforms, well-sized natural branches, and clean, dry surfaces can reduce chronic foot stress.
Keep the enclosure sanitary and dry. Remove feces promptly, clean food and water areas daily, and check perches for rough spots, splinters, or worn surfaces that can injure the feet. Watch for early redness, shiny spots, or small scabs on the footpads. Catching those changes early can prevent a minor pressure sore from turning into a bacterial infection.
Whole-body health matters too. A balanced diet, healthy body weight, regular activity, and routine avian checkups all support skin integrity and healing. If your macaw has mobility issues, over-grooms, or spends long periods on one perch, bring that up with your vet. Small husbandry adjustments often make a big difference in preventing repeat infections.
