Female African Grey Parrot, talking and whistling with certificate, in exchange for Amazon or for sale

Female African Grey Parrot, age around 5 years, gentle, does not bite, and whistles with a certificate. She had mites before but has been treated, thank God. She talks a lot, praise be to God. In three days I had her, I heard her say 'Yahoo', 'How are you?', and 'It's time to sleep'—that's all I've heard from her so far. She also whistles and imitates doorbell sounds, and she dances. Her owner left her with me; I'm offering her for sale without any conditions. You can come see her with your own eyes, examine her personally. For sale in Jeddah, or in exchange for an Amazon parrot. Final price 2,500 SAR, non-negotiable.
