Cockatoos are considered one of the most vocal species of birds. Though their vocalizations are typically limited to morning and evening time, they are widely held to be the loudest birds one can own as a pet. [2] X Research source Macaws also tend to be very loud, but their vocalizations are usually most prominent in the morning and evening, much like cockatoos. [3] X Research source Conures are prone to loud, piercing calls, but typically are most vocal when making “contact” calls to owners, rather than being “chatty” throughout the day. Cockatiels, budgerigars, lovebirds, and parrotlets are known to be vocal throughout the entire day. If you’re interested in getting a bird that won’t make too much noise, consider avoiding these birds. [4] X Research source

Leave the room when your bird begins to act out. Do not return to the room until he has stopped squawking or screaming. Return once your bird has been silent for at least ten seconds. Give him praise and reward him with a treat to show him that not making noise will earn him your affection.

Do not raise your voice in response to your bird’s volume or tone. Speak softly whenever you address your bird, and whenever you’re around him. Praise your bird every time he lowers his voice to match yours.

Always praise good behavior immediately. If any time passes between his action and your reaction, he may not associate the two. Any time your bird yells or speaks loudly, you should temporarily stop showing him affection and leave the room immediately. Use a distinct “reward” treat. Find out what your bird really likes, and save those treats for training purposes. It may give your bird the extra motivation he needs to follow your lead.

Close the curtains in the afternoon to limit sunlight exposure, and put a sheet or cover over your bird’s cage when you go to bed. Make sure there’s enough air flow coming in under the sheet you use. Do not use polyester, as this fabric does not breathe well. For best light-blocking abilities, use a black cloth.

Talk quietly. Birds will often quiet down to hear what you are saying. Never yell at your bird. Try to avoid talking loudly or excitedly around him as well.

If you have children living at home, teach them not to run through the room your bird is in. Never let children handle your bird without strict supervision. Teach everyone in your household to handle the bird gently, and to avoid quick or jarring movements around him.

Seemingly minor changes like wearing a hat, wearing certain types of eyewear, or even wearing certain colors can upset your bird. Avoid wearing whatever upsets your bird, or expose him to it slowly and gradually so he becomes used to it.

Try giving your bird a jungle gym for his cage. This will allow him to exercise and play whenever he wants to. [14] X Research source Leave toys in his cage. Birds like to feel stimulated, and may respond well to having toys, especially those that have food hidden inside and require your bird to figure out how to get the food. [15] X Research source

Birds love colorful toys. If the toy makes sounds, it will be even more desirable to your bird. [17] X Research source Give your bird some sort of puzzle-based toy. Birds love mental and physical challenges, and odds are your bird will appreciate having something to stimulate his creativity. [18] X Research source
