How loud are cockatiels?

The sound produced by a cockatiel is generally considered moderate in terms of loudness. On a scale from 1 to 10 (with 1 being very quiet and 10 being extremely loud), the vocalizations of cockatiels typically range between 4 to 6.

Cockatiels tend to be more vocal during the early morning and late afternoon, making melodious chirping sounds. While their calls are not as shrill or piercing as some other bird species, such as parrots or macaws, they can still be noticeable and become disruptive in quiet environments or when in large numbers.
