Hello Echolight and welcome to the family, glad you could join us and we look forward to hearing more about you and Zephyr, what an unusual name but I like it.
I am sorry to hear of the loss of your parakeet but happy to hear you have acquired an african grey, there is quite a bit of difference in these two birds.
I would imagine she is mimicing lots of sounds and noises and dog growls are a favorite. She will master the pretty bird and a lot more than that before long.
Read thru the many threads here for lots of useful and helpful information and ask questions if you have any, we will do our best to get you some answers and help you in any way we can.
I would go easy on the grapes, they do contain a lot of sugar and not much nutrition to them, use them as a treat, reward or a bribe if necessary.
If you have any pictures of Zephyr you would like to share with us we would love to see her.
