Merlie's birds are pair bonded, and one still attacks people.
It's really dependent on the individual birds. I actually know many caique pairs that one is more aggressive and hormonal than the other.
Also I don't think it depends on how they are raised as babies. Douglas had a pretty crap breeder, and he's awesome. While other's said they had great breeders, but their birds are more hormonal.
I don't think it's as easy to equate levels of hormones based on those reasonings.
