I have a Cockateil...Aussie...that is the sweetest bird ever!
Not exactly a Parrot, but I seriously considered one and did lots of research when I got her instead. 2 factors turned me away from a Parrot (I was looking at McCaws and Cockatoos) 1) price....both were around the $1000.00 range....even more for a baby, 2) At the time, I was not ready to commit to caring for an animal that would quite possibly outlive me!
I found that the larger species can live into their 70's!!!
Definately make sure you have an expert w/ care for exotic pets nearby...you can't exactly run to the vet w/ a bird.
