Facts

• African greys are the most talented mimics in the parrot world. With the right care, they can remain valuable household pets for up to 65 years.
  
  

Features

• African grey parrots are a deep silver-gray in color and can grow to be up to 13 inches long. They are generally fed a quality parrot food, but require some additional nutrition and socialization.
  
  

Nutritional Problems

• African greys require additional vitamin A and calcium in their diets. If these needs aren't met, the birds can fall prey to everyday avian illnesses and more long-term side effects. Lack of nutritional care can cut a grey's lifespan to 15 to 20 years and cause weight loss and disinterested, depressed behavior.
  
  

Emotional and Social Problems

• African greys are very intelligent and can become bored and aggressive if they don't receive adequate stimulation. Signs of boredom and unbalanced mental health are pouting, plucking out of feathers, destruction of their cage and aggression toward people.
  
  

Treatments

• African greys that are losing weight or displaying a lack of vitality are most likely experiencing health problems from a lack of nutrition. Leafy greens, cheese and almonds can satisfy their nutritional requirements. Greys showing signs of mental distress should receive more stimulation: at least three hours out of their cage and 45 minutes of human interaction every day.
