Yeah, definitely not as spendy as a Hyacinth. I was able to find greenwings in the web for $1200 to $1500, but I'm not sure if they were hand-raised. Looks like the reporter slipped a decimal with the $13,000 figure.
Still, not a cheap bird, and I'd be more than a little irked if someone had taught my expensive and long-lived pet to say the F-word. It's vandalism.
