Understanding Body Language of Companion Parrots -------------------------------------------------------------------------------- A complete list of bird behaviors is beyond the scope of this paper. For additional information, there are numerous books and newsletters that cover companion parrot care. Some basic behaviors will be listed below: Flashing/Dilating pupils can be a sign of aggression when coupled with tail fanning. If a bird is exibiting this behavior, he is warning you to stay away. If tail fanning is not present he could be indicating that he is nervous or happy. Growling is usually an aggressive behavior and is accompanied by dilating pupils. Feathers on the back of the neck may be raised. It is recommended you do not approach a bird when he is displaying this behavior. Beak grinding usually means the bird is content and feels safe. Birds commonly do this when they are going to sleep at night. Biting is usually an indication of the bird feeling frightened, startled or threatened in some way. Young birds also go through a "teething stage" like children and their beak is used to explore the environment. It is best to redirect the young parrot to an acceptable toy for chewing. Regurgitation in absence of illness is a sign of the bird having chosen you or sometimes one of its toys for its mate. In the wild, parrots feed each other as a sign of affection. Loud chattering is normal behavior exhibited at dusk. A bird with his head lowered below the level of the perch, leaning forward with quivering wings is usually requesting attention and is indicating he may be preparing to take flight. If he is standing still with head lowered and feathers on head fluffed, he wants his head scratched. Panting and wing drooping are usually signs that the bird is overheated, unless it is a baby that has not learned to tuck his wings in. Body and wing quivering usually indicates nervousness, fear or distrust. These birds need reassuring. It is best to speak softly to them to make them feel more at ease. Marching toward a person with head down is an aggressive behavior meant to frighten; if, however the bird is marching with the head up, the bird is requesting that you play with him. Fanning of the tail is a sure indication that the bird is displeased. Ruffled head feathers, tail fanning, extended wings, a strutting walk, and dilated pupils indicate that the bird is showing territorial aggression or trying to attract a mate. When birds feel extremely threatened and have no means to escape, they will roll onto their backs, with beak open and claws extended.
