Which Parrot Has The Worst Bite?

When it comes to bird bites, which parrot is the worst offender? Do all parrots bite often or just a certain few? What factors play into how likely a parrot is to bite someone?

Scientists have been studying bird bites for years in order to answer these questions and more.

In this article, we will take a look at what they have found and also provide some tips on how to deal with a bird bite – whether your own pet parrot has bitten you or you’ve been bitten by someone else’s.

Do parrots bite often?

Although parrots are often considered to be gentle creatures, they can actually be quite aggressive, particularly when they feel threatened.

One common form of aggression is biting, and parrots can deliver a painful bite if they feel the need to defend themselves.

In general, parrots will only bite if they feel scared or threatened, so it is essential to make sure that they always feel safe and secure.

If you have a parrot as a pet, it is crucial to handle them regularly so that they get used to human contact and do not feel the need to bite in order to defend themselves.

With proper care and handling, bites from parrots can be prevented.

What are the factors affecting the bite?

There are three main factors that affect the bite – beak size, beak shape, and bite intention.

Beak size

Beak size is perhaps the most obvious factor, as a larger beak can inflict more damage than a smaller one.

Beak shape

Beak shape is also important, as a sharp beak can cause more harm than a blunt one.

Bite intention

Finally, the intent of the bite also plays a role.

A bite that is intended to kill or maim will be much more dangerous than one that is simply meant to scare or warn.

All of these factors must be considered when assessing the potential damage of a bite.

How do scientists measure the power of bite?

When it comes to bite force, not all animals are created equal.

Scientists use a unit of measurement called pounds per square inch, or psi, to quantify the strength of an animal’s bite.

The average human bite is about 162 psi, while that of a macaw can be 500-700 psi.

But what does this actually mean in terms of practical application?

In short, a bite force of 100 psi is enough to break human skin.

So while the average person could probably take a direct hit from a parrot without too much damage, it would definitely leave a mark.

All things considered, it’s safe to say that you wouldn’t want to be on the receiving end of an animal with a powerful bite.

What types of bites are from parrots?

Parrots are known for their gentle nature, but they can also deliver a painful bite if they feel the need to defend themselves.

There are a few different types of bites from parrots and there are meanings behind their bites.

Warning bites

Warning bites are the most common type of bite from a parrot. They are usually less than half the depth of the beak and are not intended to break the skin.

Instead, they are meant to warn the person that the parrot is feeling threatened and may escalate to a more severe bite if they do not back off.


Nips are similar to warning bites but are usually deeper and can break the skin. Nips are often used by mothers to get their chicks to move away from them when they feel threatened.

Piercing bites

Piercing bites are much rarer than nips or warning bites, but they can be just as dangerous. These bites are deep and can puncture the skin, causing serious bleeding.


Tears are another type of bite that is similar to nips and warning bites but can cause more damage due to the tearing action of the beak.

Crushing bites

Crushing bites are the most severe type of bite from a parrot. They are usually only used in self-defense and can cause serious injury or even death if they hit major arteries or organs.

Which parrot has the worst bite?

The world’s largest parrot is the hyacinth macaw, which can grow up to three feet long and weigh up to 1.7 kilograms.

But despite its impressive size, the hyacinth macaw is not the parrot with the worst bite.

That worst bite parrot species goes to the green-winged macaw, which has a bite force of 2,000 psi.

According to a recent study, macaws and cockatoos have the hardest bites of any parrot species.

The researchers measured the bite force of six different species of parrot and found that macaws had the strongest bite, followed by cockatoos.

So if you’re ever bitten by a parrot, you might want to think twice before picking a fight with a macaw or cockatoo.

What to do if your parrot bites you?

Parrots are beautiful, intelligent creatures that can make wonderful pets.

However, they can also be very powerful and aggressive, especially when they feel threatened.

If you find yourself on the receiving end of a parrot bite, it’s important to stay calm.

Yelling or hitting the bird will only make the situation worse.

Instead, try to break off the attack by redirecting the bird’s attention.

Once the bird is no longer biting, take a moment to stop the bleeding and disinfect your wound.

Finally, put on a bandage to help prevent infection.

By following these steps, you can hopefully avoid any serious injury from a parrot bite.

How to train your parrot not to bite?

If your parrot is biting, there are several things you can do to train them not to.

Associate biting with an unpleasant experience

First, try squirting them with water whenever they bite. This will startle them and help them to associate biting with an unpleasant experience.

You can also try saying “no” or “ouch” in a firm voice whenever they bite.


Another effective technique is to give them a time-out by placing them in their cage for a few minutes.

This will help them to understand that biting leads to being isolated from you, which is something they want to avoid.

Build bonding with your bird

It’s important to build a bond of trust and mutual respect. Handle your parrot gently and often, and offer them treats as a way of showing affection.

Positive reinforcement

Moreover, use positive reinforcement whenever your parrot demonstrates desirable behavior.

For example, if they go a day without biting, give them a special treat or extra attention.

Be patient

Finally, be patient and consistent in your training, and soon your parrot will be well on their way to becoming a well-behaved member of the family.


Parrots are known for their sweet personalities, but it’s important to remember that they are still animals and can bite.

The factors that affect how likely a parrot is to bite include beak size and shape, and the intention of the bite.

While no one wants their bird to ever bite them, it’s important to know what to do if it does happen.

Keep calm and don’t punish your bird – just stop the bleeding, disinfect the wound, and put on a bandage.

You can also train your bird not to bite with positive reinforcement.
