Behavior/Health Concerns:  Lilac-crowned Amazons love to eat, so owners must watch the portions fed. Most Amazons also have the tendency for obesity. Vary their diets with fruits, vegetables and pellets. They are also susceptible to vitamin-A and calcium deficiencies and upper respiratory infections. Larger cages are optimal for lilac-crowned Amazons, so they have room to move and climb around, play with toys and exercise. Holloway recommends parrot owners have a separate bird room for their lilac-crowned Amazons to be housed when company is around and to give the pet bird a private area to get proper rest.
