It depends on your personality as well. I personally like
the "Fraidy Cat" bird. He shows intelligence and isn't going to
let just anyone pick him up. But that's just my personality, you
see. I like a bird that has a bit of self respect You might like
a more affectionate bird.
I agree with Betty here. Be sure you know what you are getting
in for. It truly is like adopting a 3 year old child that will
remain three years old until it is 70 years old or so and it
will never grow up and be able to get a job and fend for itself.
It is a lifetime commitment.
And I personally think there is a big difference between getting
an Amazon as a second bird versus getting a second Amazon but I
will leave that debate to the others.
I have never had more than two Amazons at a time and one was a
rescue who died of old age and a bad heart. If you think an
Amazon can be cranky, try dealing with one that is 50 and having
chest pains. :)
