Bumblefoot (ulcerative pododermatitis) is a bacterial infection and inflammatory reaction that causes painful sores and lesions on the surface (integument of the plantar) of one or both feet.
Caged parrots are prone to bumblefoot because they spend more time perching than wild birds.
Bumblefoot is commonly caused by hard plastic or sandpaper perches, wire flooring, insufficient vitamin A, weight gain, overgrown claws, and cuts from sharp and broken objects.
Bumblefoot can be excruciating. Eventually, a parrot won’t be able to stand on the affected foot. The condition can be treated with antibiotics, but problems can reoccur if the cause isn’t removed.
What Bumblefoot Looks Like
Bumblefoot is characterized by hard, puffy scabs that look like small blisters. The scabs can be red, black, or brown. The foot may also be swollen and the tissue inflamed.
Sometimes, bumblefoot manifests as a boil or welt on the skin’s surface. These are pus-filled and require drainage to relieve the pressure and discomfort.
In the advanced stages of bumblefoot, painful abscesses appear as clusters on the skin. A parrot’s health is in grave danger when the skin turns black.
According to the Hagen Avicultural Research Institute, bumblefoot has 7 grades of infection:
| 1: | The parrot’s foot develops a shiny, reddened surface with a small lesion. |
| 2: | The infection comes into contact with the lesion, and tendons can be seen through the skin. |
| 3: | Ulcers that appear swollen, pus-filled, and rough around the edges. |
| 4: | A painful necrotic plug forms in the ulcer’s center. |
| 5: | Swelling and edema surround the area of necrosis. The foot and digits become filled with fluid, making them appear swollen. At this stage, tendons and metatarsal pads become infected. |
| 6: | The digits are swollen, and the foot’s necrotic flexor tendons rupture, causing loss of feeling. |
| 7: | Bone infection (osteomyelitis) occurs, eventually resulting in death. |
Causes of Bumblefoot
Bumblefoot occurs when bacteria, like staphylococcus, enter the parrot’s foot due to an accident, injury, cut, scrape, or wear and tear.
According to the MSD Veterinary Manual, bacterial infections in captive birds are caused by poor husbandry, low-quality nutrition, and unsanitary environmental conditions.
The other causes of ulcerative pododermatitis include:
Unsuitable Perches
As parrots spend most of their time standing on their feet, poor-quality perches are a problem.
Plastic perches with rough or sharp edges can cut the skin, allowing bacteria to enter the wound. Abrasive perches or perches covered with sandpaper can also penetrate the skin.
Parrots need natural perches of various widths to exercise their feet and improve their grip. They should also be cleaned regularly to remove bacteria from the surface area.
Wire Flooring
Wire cages can cause injury. To protect the feet from cuts and abrasions, hard, sharp, and rough surfaces should be covered with a softer material, like newspaper or paper towels.
Overgrown Nails
When a parrot’s nails grow too long, they can penetrate the skin, allowing bacteria to enter.
Most parrots control the length and sharpness of their claws with a pedi perch and abrasive items or rely on their owners to keep them at the right length.
Splinters
A splinter can cause bumblefoot because bacteria only need a small access point to enter the skin. Splinters caused by damaged wooden objects inside the cage can be culprits.
Vitamin A Deficiency
Veterinary Research Forum explains that a vitamin A deficiency can cause bumblefoot. Budgerigars are particularly susceptible because seeds are low in retinol.
Vitamin A deficiencies cause dry, flaky skin that lacks elasticity and strength. As a result, parrots lacking retinol have feet more prone to wear and tear, cuts, and trauma.
Obesity
Obesity, caused by overeating and a lack of activity, makes bumblefoot more likely.
Heavier parrots exert more pressure on their feet, resulting in broken skin, injuries, and pressure sores. This leaves small entry points for bacteria to penetrate.
Tobacco Usage
The handling of parrots by tobacco smokers can leave traces of nicotine behind, causing skin irritation. Parrots sensitive to these contaminants may start pecking and biting their feet, causing damage.
Cleaning Products
Many cleaning disinfectants are highly toxic. Even if you use bird-safe cleaning agents, ensure the surface area is completely dry before returning the parrot to its cage.
Signs of Bumblefoot
If owners don’t notice the warning signs of bumblefoot, the infection will worsen, causing life-inhibiting mobility problems or death. The symptoms include:
- Limping.
- Lameness.
- Standing on one leg.
- Painful foot swelling.
- Sores, legions, or abscesses.
- Loss of appetite.
- Unhappy vocalizations.
- Refusal to let you near the foot.
- Overgrown nails.
Once limping and lameness become evident, the condition has progressed.
Treating Bumblefoot
Untreated bumblefoot usually worsens and spreads to the top of the foot (dorsal). Once bacteria get into the wound, bumblefoot develops quickly, so follow these simple steps:
Clean The Wound
Before bumblefoot develops, the foot will have a cut, graze, scrape, spot, or skin irritation. At this stage, you may be able to prevent bumblefoot by washing the foot in warm water with antiseptic.
Then, the foot can be dried and treated with an antibacterial cream. Ensure the cage is kept clean and dry to stop bacteria from entering the wound.
You may need to bandage the wound while it heals. The parrot won’t like this, so ensure the bandage stays in place. Repeat the cleaning process twice daily, checking for signs of infection.
Antibiotics
Oral antibiotics and creams control the infection, preventing it from spreading. Anti-inflammatory medications can also reduce foot pain. If the infection is severe, vets prescribe erythromycin or penicillin.
Epsom Salts
Epsom salts are a natural and effective way to treat minor bumblefoot infections. Follow these steps:
- Partially fill a sink with warm water and add Epsom salt.
- Wrap the parrot in a clean towel, keeping the wings secure and the feet out.
- Soak the affected foot in the solution for 10 minutes to loosen the ulcer’s necrotic plug.
- Try to remove the necrotic plug, teasing it ever-so-gently. If it starts to bleed or refuses to loosen, soak the foot for another 10 minutes.
- Attempt to loosen the necrotic plug again, noting the parrot’s stress levels.
Removing the necrotic plug separates the infected skin from the healthy tissue underneath.
Balanced Diet
A vitamin A deficiency has the following adverse symptoms:
- White patches on the tongue.
- Abscesses inside the mouth.
- Labored breathing.
- Excess oral mucus.
- Nasal discharge.
- Eye swelling.
- Depression.
- Diarrhea.
- Loss of appetite.
- Secondary infections.
- High hatching mortality.
- Faded feathers and skin colors.
Foods high in vitamin A include:
Under vet advisement, you can give a parrot vitamin A supplements.
How To Prevent Bumblefoot
A better cage setup and the right foods can prevent a parrot from injuring its feet and bacteria entering the wound. Bumblefoot prevention methods include:
Clean Cage
The cage must be kept clean and sanitary to keep bacteria at bay.
Feces and spoiled food will coat the bottom of the cage. A parrot with a slight foot abrasion is likelier to develop bumblefoot because the cage is a breeding ground for bacterial microbes.
Parrots’ cages, toys, and dishes should be cleaned at least once weekly with a bird-safe disinfectant soap and warm water. Disinfectants should be left to air dry for 15 minutes before being cleaned off.
No Synthetic Perches
Parrots need perches made from natural materials, like wood. Avoid synthetic materials by removing all plastic perches and toys that can cut or penetrate the skin.
Also, ensure that all perches inside the cage are a suitable diameter for the feet. If perches are too wide, the foot will stretch to wrap around them, while too narrow perches exert pressure on the feet.
A parrot should be able to wrap its feet comfortably around the perch, but the forward-facing toes shouldn’t overlap the backward-facing toes.
Pedi perches should never be positioned where parrots commonly perch because excessive usage can scrape the skin from the feet. Limit use to 2-3 days per week, perhaps every second day.
Cut The Nails
Keep the parrot’s nails trimmed. Some owners are comfortable doing this at home, but you can take the parrot to the vet to get it done. The signs a parrot needs a nail trim include:
- Long, misshapen nails.
- Avoidance of perches.
- More time is spent on flat surfaces.
- Difficulty walking comfortably.
- Inability to grasp food, toys, and perches.
- Nails getting stuck on clothes and fabric.
- Scratches and scabs where the parrot itches itself.
If a parrot is prone to cuts and abrasions on its feet, trim its nails instead.
Bumblefoot is a treatable medical condition. The sooner it’s identified, the better the prognosis.
