The African grey parrots ability to talk and mimic sounds makes it a charming companion. African grey owners often report that their greys oftentimes talk in context and can understand their peoples emotions. The African grey parrot is not just a top talker—this bird is also known for its extreme intelligence， which gives it the name “The Einsteins of the bird world”.
The bird is medium?sized， dusty?looking and almost pigeon?like. It has a bright red tail， intelligent orange eyes， and a stunning scalloped（扇形的） pattern to its feathers. Its diet in the wild consists mostly of nuts， seeds， fruits， and leafy matter.
At home， African greys need plenty of toys that challenge their intelligence， such as food searching and puzzle toys. Nutri?Berries by Lafeber Company are a perfect choice， which， with a balance of grains， seeds and other nutrients in the shape of a berry， encourages African greys to hold， bite off， and even do other things， just as they do in the wild.
African greys seem especially affected by stress and disturbing noise in their environment and can be put more at ease by placing one corner of the cage against a wall compared to in the middle of a room.
African grey parrots are more likely to suffer from lack of vitamin A/beta?carotene， and therefore benefit from eating vegetables high in beta?carotene， such as cooked sweet potato and fresh kale. Lack of vitamin D is another concern， especially for greys on a poor diet. Offering a balanced， pill?shaped diet， such as Nutri?Berries， helps prevent vitamin and mineral shortage.
