How Bad Are Macaw Bites? Bite Force, Injuries & Advice

Macaws are majestic birds easily recognized among other parrots due to their colorful plumage and impressive sizes. If you’re lucky enough to have one as a pet, you know how smart, vocal, and surprisingly gentle they are. However, they also have powerful beaks; their bite can lead to serious illness if the wound is left untreated. So, although they are not considered aggressive birds, there are a few precautions to take when dealing with such a pet. Read on to find out how bad macaw bites are, how to treat them, and how to keep your bird from biting.

divider-birds How Strong Is a Macaw Bite?

The force of an animal bite is measured in pounds per square inch (psi). For example, parrots can apply 200 psi of pressure with each bite; this is sufficient to produce significant crush injuries. For comparison, the American Pit Bull can produce 235 psi, humans can produce 120 psi, and the great white shark can produce 600 psi.

A macaw can produce 330 psi of pressure in one bite, which could easily crack a Brazil nut. Imagine if this pressure was applied to your finger by an angry macaw: It would be enough to seriously damage or even break your finger.

Can You Get a Disease From a Macaw Bite?

Yes, you can get sick from a macaw bite (or any bird bite, for that matter). Infectious diseases transmitted to humans from animals are called zoonoses. Here are a few of the diseases your macaw can pass on to you through their bite:

Psittacosis: This disease is caused by the bacteria Chlamydophila psittaci, found in 40% of birds of all species. Although many infected pet birds show no signs of the disease, they can still pass it through their bites.

If your macaw bites you—even lightly and barely leaving a scratch—and you leave your wound untreated, you are at risk for psittacosis. Indeed, the bacteria that penetrate your skin can cause fever, rash, headache, or dry cough. In most cases, the infection is not severe and can be easily treated with antibiotics. But in very rare cases, it can lead to pneumonia in some people.

Salmonellosis: The symptoms of Salmonella in healthy adults are usually limited to diarrhea, abdominal cramps, fever, and vomiting. These symptoms typically go away without the need for treatment. However, people with weakened immune systems—such as children or the elderly—can become seriously ill or even die after contracting the virus. If you think you may be infected with Salmonella, talk to a doctor as soon as possible.

Pasteurellosis: It is the Pasteurella bacterium that causes this disease, which is characterized by a skin infection that can be severe. Humans are most often infected with Pasteurella through a bite from a clinically healthy animal and then present a reaction localized to the bite point: a red, hot, swollen, and very painful sore.

How to Treat a Macaw Bite

Treat your injury as soon as you can to reduce infection or other complications. Dealing with a macaw bite is similar to how you treat any other cut, but you should be even more careful with infection due to the source of the injury.

Important: If your wound gets worse, see a doctor as soon as possible. You will probably need antibiotics to prevent any risk of a more severe infection.

  • Step 1: Evaluate your wound. Did your bird only scratch your skin as a warning, or is it more serious? If it’s just a scratch, you may be able to relieve yourself with a good cleanse, cold compresses, and ibuprofen. However, if the bite has caused bleeding, is very deep, or is on the face, you should see a doctor right away.
  • Step 2: Clean your wound thoroughly. Before going to the doctor, clean your wound thoroughly with lukewarm water and antiseptic soap. This will reduce the growth of bacteria on the fresh wound. Then, use a hydrogen peroxide solution to disinfect your wound completely.
  • Step 3: Apply antibiotic ointment. After your bite has been adequately cleaned and disinfected, apply a thin layer of an over-the-counter antibiotic ointment, which should be in your first aid kit. It can also be used to treat minor cuts or wounds that happen to your macaw.
  • Step 4: Cover the wound with a bandage. After disinfecting your wound, cover it with a sterile bandage to keep it clean and dry. When you need to handle your bird, be sure to wear gloves to protect your bandage. In addition, this will prevent bacteria in your macaw’s cage or feces from coming into contact with your injury and making it worse.


How Do You Stop a Macaw From Biting?

Pinching is natural for a macaw. It uses its beak to touch, taste, and discover its environment but also to eat and defend itself.

However, it rarely uses its beak against its fellows in the wild, with whom serious conflicts are rare. Instead, a macaw will bite only to protect itself against snakes and other predators. Thus, biting is not part of its usual instincts. However, typical behaviors in nature are not necessarily adapted to living with humans.

So, if your macaw bites you, ask yourself the following questions:

  • Under what circumstances did the bite take place?
  • Has anything changed in the macaw’s environment (painting walls, adding new toys, moving furniture, etc.) or in its behavior? Did another pet or a rowdy child scare it off?
  • Has your macaw recently arrived at your house? Is it old or still young? Did you adopt it from another breeder? If so, what behavior did it have in its old house?

The important thing here is to target the trigger. Since biting is not normal behavior in the macaw, we can logically deduce that it can be reinforced or stopped with an appropriate method.

Pay Attention to Your Bird’s Body Language

Macaws are motivated by the desire to control or to survive. So, they can bite if they are scared, in pain, or experiencing hormonal surges. But sometimes, the bite only happens because your pet bird doesn’t understand what behavior to adopt – he is confused.

So, the best way to avoid possible injury to you is to observe your macaw’s body language:

  • They ruffle their feathers when they are unhappy.
  • They speak loudly by faking pecks.
  • Their pupils dilate and contract quickly.

By showing these signs of nervousness, your bird is telling you that it’s best to wait until later to make physical contact with them.

Use the Positive Reinforcement Method

The best way to stop your bird from biting is to encourage positive behavior. You are the nurturing hand and as such, identified as an entity dominating the bird’s clan. The embarrassing behavior can be discouraged in the first place by a marked disapproving look. The empathy felt by these feathered beasts is such that your attitude will not go unnoticed. You can accompany this with a “no” (curtly and without shouting).

Then, lift the bird onto your hand, accompanying the movement with one word in a soft but firm voice, then onto the other, and repeat three to four times. This is called “the ladder.” This peaceful maneuver aims to make your macaw understand that you are the reference member of the group, not it.

Above all, never have a violent reaction toward your winged aggressor, as you will permanently distort your relationship with it. Slapping it on the beak and saying “no” also has no effect, as studies have shown that pecking is part of parrot play. The screams that go with it are also an inappropriate response since the bird will see it as a game.

How to Teach Young Macaws Not to Bite

Young birds have no idea how strong their beaks are, especially if they have been isolated from their siblings. In addition, play between the beak and human fingers is not recommended because cries of pain are perceived as stimuli in a game. Without knowing it, you are teaching your bird to bite.

Unlike us, macaws seem to like being shouted at because it resembles their primary mode of communication. Therefore, a cry of pain is a positive response to a given behavior. Imagine their joy when they pinch a chubby finger and hear your exclamation—it becomes a fantastic game for them!

divider-birds Conclusion

Much like cats and dogs, untrained or poorly trained macaws can develop aggressive behaviors such as biting, which can inflict a wide variety of injuries, ranging from superficial puncture wounds to open fractures due to the crushing action of the bird’s beak.

But with a bit of patience and using the positive reinforcement method, you can stop your macaw from biting and prevent yourself from possible serious injury. In any case, do not hesitate to consult a parrot specialist or an avian veterinarian.
