Cockatiel Hissing and Biting: Possible Reasons and Solutions

Cockatiel Hissing and Biting

Cockatiels are among the pet birds who learn and like communicating. When happy, they whistle, mimic, grind their beak, and fluff their feathers. However, behaviors like hissing and biting still frustrate most people, especially new pet owners.

So, why is cockatiel hissing and biting? A cockatiel will hiss and bite for many reasons, including fear, anger, or being territorial. The biting will mostly happen after a hiss, which serves as an early warning. It is best to find a solution sooner before they develop a habit.

Sometimes it becomes confusing to understand some pets’ behavior, especially if they are being aggressive. In this article, you will learn about cockatiel’s hissing and biting habits and why it happens.

Why Does My Cockatiel Hiss and Bite?

Like many birds, cockatiels use their beaks for many activities, including using them as hands for climbing. Most of these activities are okay, but when the bird hisses or bites, it means something is wrong. Below are some possible reasons your pet bird might be hissing and biting you.  

Why Does My Cockatiel Hiss and Bite

1. Fear

Back in mainland Australia where cockatiels are naturally found, they’re prey to predators like hawks and eagles. In captivity, their first instinct when threatened by a foreign object or person is to hiss as a warning. If this warning is not heeded, the birds will bite in an attempt to defend themselves.

2. Territory

Cockatiels are territorial birds that can be attached to things like their cages, toys, and also their caregiver. If their personal space is invaded, especially their roosting place, the birds will become aggressive to the invader. These avian pets will also hiss and bite each other for dominance.

3. Breeding

Cockatiels exposed to a decent amount of natural light will be able to breed before they’re one year old. During this time, the female cockatiels will be more aggressive if you come near their nesting place. Male cockatiels will also bite during this period since they stick around after mating to protect the young ones.

4. Mood

Like most animals, cockatiels get different moods like anger or boredom. Other ways to determine a cockatiel’s mood include looking at its head crest and wings. When in a bad mood, the bird will nip and bite your finger if you pet it.

5. Fatigue 

Your budgie will bite you when fatigued. If it has not rested or had enough sleep, do not try playing with it. Instead, get it back into the cage and leave. Also, don’t wake it from sleep when resting. It may wake up angrily and bite you. 

A playful pet will also nip on your fingers to get your attention. When playing, you should frequently rub their head, something that male cockatiels in particular enjoy. Sometimes, these pets bite if they are hungry or when they haven’t eaten enough.

How Do I Stop My Cockatiel from Biting?

You must first determine why the bird is biting to provide the right solution. Sometimes this will be a playful gesture accompanied by a joyful whistling. However, some habits go on for some time, and the following solutions will help try to stop them.

How Do I Stop My Cockatiel from Biting
  1. Bond – Bonding is crucial, especially with new pets. After familiarizing yourself with your pet, it will be less likely to bite you as it would a stranger. The bonding process takes time and patience, but it’s a worthy effort since you will be able to determine future problems.
  2. Change its environment – Changing the bird’s environment can help solve your cockatiel’s attachment to items like its cage and toys. Territorial aggression can also be between two pets, which you can solve by placing them in the new bigger cage at the same time.
  3. Approach it gently – Startling your avian pet will make it bite you. Approach it gently while calling its name to make it feel safe and comfortable. Avoid banging its cage door, which also startles it.
  4. Don’t put your hand in its cage abruptly – Even if you are used to your pet, if you push your hand in its cage unceremoniously, it will bite you. Place the hand gently and wait for it to hop on it so you can take it out.
  5.  Feed it enough – If you suspect your bird’s biting habit is due to hunger, you should check its diet. Feed your cockatiels enough food, and feed them enough. A mature cockatiel can take up to 40 grams of seeds and pellets to be satisfied.
  6.  Place the cage higher – placing them higher will give them a feeling they’re on a tree. This will also mean they see your face before your hands, which boosts their confidence.
  7.  Distract it with toys – If your cockatiel is using your fingers to play, you can add new toys to its cage. They like colored toys with movable parts and also appreciate chewing wood.

Understanding your budgie is the most important thing. You should know how they respond when distressed, happy, and when hungry. Whatever the reason for biting, you should resolve it in the above ways. You must also become strict and tell your budgie a stern no to prevent this behavior from becoming a habit. 

Does Feather Clipping Help Calm An Aggressive Budgie? 

Male parakeets especially can develop an exaggerated sense of pride. Mostly this happens when they have overgrown flight feathers. These feathers build excess confidence in the budgies, such that they overlook any training you had taken them through. If your fully flighted male budgie won’t hear any of your training and keeps biting you, this may be the problem

Does Feather Clipping Help Calm An Aggressive Budgie

Once you identify this is the issue, you should contact your avian veterinarian for clipping. Remind them not to overdo it because you still want your pet budgie to enjoy flying around. A minor clipping will remind the bird that it is not entirely in charge, and it may help tone down its aggressiveness.

But, you should only do this after you have tried all the other options we talked about. Remember, after clipping, the feathers will molt and regrow, so it is only necessary when it affects your budgie’s behavior. You don’t want to take your budgie through all that, yet they are experiencing hormonal issues.

3. Why Is My Cockatiel Hissing at Night?

Cockatiels experience night frights more commonly than other avian pets. These birds are easily flustered by night sounds, which sometimes make them hiss. Since they don’t roost in the open at night, cover their cage to simulate a nest and to make them feel more secure.
