The best talkers tend to be African Greys. These birds love to imitate electronic sounds, like the phone and the Internet dial up. They can also call the dog, and other family members, and then laugh when they come running! These are shy, often one-person birds that thrive in a controlled environment – they do not like a noisy, frenetic environment with a lot of commotion!
It is best to give them as much socialization as possible at a very young age. These birds need to know that they are secure and safe, and that nothing is going to harm or attack them. (The socializing and security is an excellent way to begin and continue any parrots life).
