Cockatiel

Cockatiels are popular as pets and are fairly friendly birds. They're also highly vocal, and if they're upset or bored, they'll chirp loudly. They can even learn to whistle a variety of tunes, perform stunts, and even talk. The decibel level of their noise is 123, so it is one of the loudest birds on this list. It's enough to irritate your ears, particularly if the bird is close by.

Cockatiels are endemic to Australia, where they can be found mostly in dry or semi-arid areas with plenty of water. The species, which is mostly nomadic, will go to where there is food and water. They usually travel in pairs or small groups. Cockatiels in the wild eat a variety of seeds, including Acacia, wheat, sunflower, and sorghum. They frequently devour cultivated crops, much to the chagrin of many farmers. The most fertile southwest and southeast regions of the country, as well as the deepest Western Australian deserts and the Cape York Peninsula, are devoid of them.
