The African Grey is extremely

The African Grey is extremely - intelligent, perhaps topping all other parrots in its ability to learn new things throughout a lifetime. Adult greys are considered shy and introverted, and usually bond with only one person, being aloof with everyone else. They are also one of the most rigid and pattern oriented of all parrots, being keenly observant and sensitive to the slightest change in routine. Excellent talkers and mimics, these birds can accurately imitate specific human voices and household noises such as the doorbell, telephone, or microwave. As very empathetic and emotional birds, greys have distinct personalities and can be demanding of their owner's time and attention.
