|Let's Celebrate Pet Birds!|
T.J. Lafeber D.V.M.
Why would a bird pick his own feathers out when he needs them for survival? The main function of feathers is not for flight but is to keep the body warm. Without complete feathering birds are susceptible to chilling.
Only birds with psychological problems would self-mutilate. They develop psychic behavior for a number of reasons-confinement, stress, fear, disease, parasitism, malnutrition, inactivity, boredom, etc.
The job of diagnosing the cause of these actions can be very difficult and sometimes impossible, It an effective treatment is to be had the cause needs identification. Even then, the treatment may be long. See your veterinarian.
