Highly intelligent African Grey parrot available for adoption

Okay, I'll try to explain even though I'm not very good at writing ads. This African Grey parrot is called Pablo, and he's lived with me for almost five years. At first, he was very shy, but over time he started copying sounds from around the house. Now he imitates the ringing of the telephone and sometimes even my brother's laughter, which always surprises visitors. He likes to be out of his cage for several hours a day and walk on the table while I'm working. He's not aggressive, but he needs someone who understands parrots because they are very intelligent and sensitive animals. The reason I'm looking for a new home is that my job requires me to travel often, and I can no longer spend enough time with him. I would prefer him to live with someone who can talk to him and interact with him every day.
