The smartest birds, well, able to learn are the African grey parrots.
The life expectancy of many parrots ranges from 50 to 70 years, which means that your bird may very well outlive you. Of course not all parrots live to be 70 or 80 years of age.

An adult African grey parrot generally has a weight of 500-600 grams. Some individuals exceed this.
The smartest parrots are the Grey Jaco, but they are very difficult to keep as pets, they are more sensitive to changes than other kind of parrots, they need much care and attention.
Its fairly unlikely but birds know just as much as you teach them.
actually, a bird memory can last up to 2 years...a bird has a very good memory and it can last even longer if it has been trained :)
Big. While the African Grey is not the largest of the pet parrot species, it is a large bird and can reach about a foot in length, meaning that special considerations, such as large flight cages and play gyms, must be considered.
It greatly varies on the type of bird. Macaws, for instance, are not generally know as "talkers". African Greys, on the other hand, can learn to say literally thousands of words. So it varies by the bird, though even if the bird is part of a species of talkers does not mean they'll be guaranteed to talk themselves.
