There is no question that all the research and the intelligent scientific studies out there will tell you that African Greys are better talkers and of the highest intelligence. I agree. However, how much research has been done on Amazons? Now where near as much. Yes, As seen here, Dayo has an extensive vocabulary, as does Talon. She far out speaks Rikki. Nilah, my amazon can say even more than Talon, and she uses it in context as does Talon. Tonel quality, greys have that advantage, Nilah speaks in my voice and the various tones that I use, where as my greys will speak in the many tones of our family and mimic the bells, phone, dings, that they hear in their everyday life. As far as sheer volume, Amazons can far out speak many greys. Just search U-tube and you will see they can do more than simple phrases, they can sing entire songs.
Nilah does not mimic the sounds of the house as the greys do, but she does speak the sounds of our pets and humans exactly as we hear. This is my opinion, not meant to start a debate, but I am sure that those that own both species will say, that Amazons can be incredible talkers. Just like African Greys, some are incredible talkers, some barely speak if at all. I am certain this is true for Amazons as well. I just want to vocie my opinion, that I feel Amazons can be better talkers than Greys as the case with my flock.
This is based on MY experience of having BOTH species, Nilah,a Yellow Naped Amazon, 13 months old, I have had her since she was 6 months old. Talon, a Timneh African Grey, 4 years & 6 months old, I have had her since she was 8 1/2 weeks old.
Rikki, a Congo African Grey, 4 years & 4 months, have had her for 3 years.
