I have no idea. They are both really good options. I can only personally attest to the white winged parakeet but not the yellow chevroned parakeet. I can say that from what I know I think they both have similar personality. I would go with whichever one wins your heart. You definitely can't go wrong either way.As you know I’ll be getting a Brotogeris but I’m having trouble choosing between a CWP or WWP Any ideas?
