African grey parrot accustomed to living with people

This African Grey parrot has lived with our family for several years and has become completely accustomed to a home environment. In the mornings, he's usually perched on his perch in the living room while someone prepares coffee or breakfast, listening intently. He sometimes tries to repeat sounds he hears frequently, such as the telephone ringing or simple words. He's not a noisy bird; rather, he observes everything that happens around him. When someone approaches and speaks to him calmly, he tilts his head as if trying to understand. He has always lived indoors and is used to a quiet environment. His diet includes parrot seed mix, fresh fruit, and occasionally nuts. Due to a major change in our family life, we will be moving to another country and won't be able to take him with us, so we are looking for someone who can dedicate time and attention to him.
