Read the text below. Pet birds have been described by some as moody: playful and loving one minute, demanding and aloof the next. Sometimes very obvious and sometimes very subtle, a bird's body language can give you insight into what your bird needs and wants.
Although parrots communicate through different body languages, the following behaviors are observed in most pet birds, some more often than others and some more prominently than others. Observing your bird's vocalizations can be very telling.
Vocalizations
In the wild, birds use various vocalizations to warn others of danger, attract mates, protect their territory, and maintain social contacts. Most birds are highly vocal and many times may be trying to communicate with you.
Singing, talking, and whistling: These vocalizations are often signs of a happy, healthy, content bird. Some birds love an audience and sing, talk, and whistle the most when others are around. Some birds will remain quiet when others are watching.
Chattering: Chattering can be very soft or very loud. Soft chatter can be a sign of contentment or can be the practice of a bird learning to talk. Loud chatter can be an attention-getter, reminding you that she is there. In the wild, birds often chatter in the evening before going to sleep to connect with other flock members.
Purring: Not the same as a cat's purr, a bird's purr is more like a soft growl that can be a sign of contentment or a sign of annoyance. When purring, the bird's environment and other body language should be taken into consideration to determine what the bird is expressing.
Tongue-clicking: By clicking its tongue against its beak, your bird may be entertaining herself or asking to be petted or picked up.
Growling: Not heard in all pet birds, growling is an aggressive vocalization. If your bird is growling, examine her environment and remove anything that may be bothering her. Growling birds should not be handled as they do not want to be touched.
