Why Is My Bird Grinding Its Beak? Is It Normal? (Surprising Truth!)


Birds are playful and active. They thrive well when provided with enough stimulation and are occupied. However, if left alone for a long time with nothing to entertain them, they can get lonely and engage in some weird behaviors. If your bird is used to grinding its teeth, then it’s time to understand why this behavior is happening and what can be done about it.

11 reasons why your bird is grinding its beak:

1. A Way of Expressing Its Happiness

When your bird is comfortable and happy, it will express itself to show satisfaction. As the bird can not vocally say it out, it will use various body languages to pass the message. Beak grinding is one of the movements you are likely to observe.

Thus, if your bird is grinding its beak accompanied by relaxed signs such as preening, wing stretching, and standing on one foot, then your bird is showing you that it’s satisfied with its living conditions and the surrounding environment.

2. The Bird Is Relaxing Itself

As your bird prepares to take an afternoon nap or sleep during the night, you are likely to hear grinding sounds coming from the cage. This is a normal occurrence and a way of preparing and relaxing to rest well. 

3. Maintaining the Health of the Beak

Birds use their beaks for feeding, preening, and defending themselves from predators. Beak grinding helps to trim, sharpen, and keep the beaks in good shape.

As beaks are made up of keratin, they continuously grow and need to be trimmed to prevent overgrowing. Untrimmed beaks can affect the birds’ general well-being as they can lead to accidents by getting stuck in toys or hinder the bird from feeding well.

4. Out of Boredom

Birds are very active and need a lot of stimulation to be happy. Lack of a companion or toys to play with can make your bird bored, and it will revert to beak grinding to keep itself entertained.

5. Your Bird Is In Pain

Beak grinding can also be seen in birds that are injured or suffering from a viral infection. It is a way of soothing themselves and coping with the stress and pain of being sick.

6. A Sign of Exhaustion 

If your bird is grinding its beak louder than normal, it’s an indication that your bird is tired and needs rest.

Observing the behavior frequently during the day is a sign that your bird is not getting enough sleep at night.

Hence, you need to improve your bird’s sleeping habits by covering its cage at night and reducing distractive noises and movements around it at night to ensure that it gets 10-12 hours of sleep.

7. Helps the Bird to Eat

Regular grinding trims beaks, thus making them sharper. Which helps birds crack open the hard shells of seeds and nuts.

Through beak grinding, birds are also able to break food into smaller pieces. This makes eating easy for sick birds or young birds that are learning to eat on their own.

8. Your Bird Might Be Stressed

Birds can grind their teeth when stressed due to a change in environment, the presence of a new pet, or a new member of the family.

When stressed, the beak grinding will be louder and more frequent than normal. If you notice such behavior in your bird, immediate action is required to remove the stressors.

9. Means of Communication Between Birds

As birds live in flocks, they communicate with one another using body language.

A bird will grind its beak:

  • To signal readiness for mating or when setting territorial boundaries.
  • As a sign of aggression or submission through posturing the beak.
  • When establishing social hierarchies within their flock.

10. The Bird Is Preening Itself 

Birds use their beaks to rearrange their feathers as well as apply the oily substance to keep them well groomed and waterproof. As they preen, you will hear the clicking sounds. 

11. Maintaining Hygiene

Beak grinding helps remove dirt particles and other food remains from the surface of the beak, thus, keeping the bird healthy and disease free.

Beak Grinding Meaning

Beak grinding is when a bird rubs its upper and lower beaks back and forth against each other. 

The behavior can be observed at night or during the day in birds like parrots, finches, and raptors.

Beak grinding sounds like a repetitive scratching or clicking sound, similar to scratching a rough surface with your nails.

Is Beak Grinding Normal?

Yes, it’s normal for your bird to grind its beak. You shouldn’t be worried about this behavior, as the bird is not in pain.

Hence, you can expect to see beak-grinding behavior in your bird from time to time.

So, why do birds grind their beaks when they sleep?

Birds grind their beaks at bedtime as a sign of contentment, happiness, and relaxation. It’s a more frequent behavior, as it’s a way of soothing themselves to sleep.

Is Beak Grinding Good?

Yes, it is good for your bird to grind its beak. It is a sign that your feathered friend is relaxed and happy, and it helps keep the bird’s beak trimmed.

You should be concerned if your bird doesn’t grind its teeth, as it might be an indication of an underlying medical condition.

Is Beak Grinding Bad?

As much as it is healthy for your bird to grind its beak, you should be concerned if the grinding:

  • Is observed during other periods other than before bedtime.
  • Lasts longer than normal.
  • The beak grinding is accompanied by some destructive behaviors.

Always ensure that you provide safe chewing and foraging toys for your bird to be entertained with.

Do Sick Birds Grind Their Beaks?

Yes, sick birds can grind their beaks. A bird suffering from gingivitis or infection is likely to exhibit grinding behavior.

However, before ruling out that your bird might be sick, check out for signs of lethargy, fluffed-up feathers, decreased appetite, weight loss, drooping wings, a running nose, sleeping more than normal, or difficulty breathing.

If you can see any of the signs in your bird, have it checked by the veterinarian for treatment and medication.
