Birds are becoming popular as pets. But some owners of birds don’t know how to communicate with their pets. Therefore, they don’t know what their pets need or want. Owners can learn how to read the body language of a bird, including movements of the wings, the tail and the beak(喙).
Wings
A bird can communicate with others through the use of its wings. A bird may lift or open its wings as a sign of happiness. But if the bird starts to open and to close its wings, it may express anger or pain. If a bird fails to fold its wings against its body, and instead lets them hang by its side, it may be ill.
Tail
Birds often use their tail feathers to communicate, so an understanding of this behavior will help the owners. Happiness is expressed by tail movements, such as up and down. However, if a bird fans its tail feathers out, it is usually a way to show anger.
Beak
While a bird’s beak is used mainly for eating, the bird may also communicate by using beak movements. For example, a bird may click its beak once as a greeting, and several clicks can be taken as a warning. Birds may sometimes bite, but it is often difficult to find out the reason behind this — birds bite as a way to protect their homes, to show anger or to express fear.
