One of the most critical elements of parakeet health is the attentiveness of the owner to the daily activities of his or her parakeet. If you are a parakeet owner, you will become familiar with the many idiosyncrasies of your own bird, and be better able than anyone else to judge if something in his or her behavior is a little off or not.Parakeets are not good at telling us if they are in pain or feeling sick. Frequently, they will even try to cover up any sign of illness. This is instinctual behavior based on living in the wild, where a bird who is ill will be the first one to become prey to its predators. That means that by the time your bird starts to act differently than normal, he is already very ill.
