Well, definitely stay away from those trouble making blue fronts

:54: (Just kidding!).
Honestly, it depends on what traits your friend is looking for in a new bird? What about amazons made him think he'd like to have one? The smaller ones like lilac crowns and green cheeks tend to be calmer, have 'less' hormonal issues and a little bit 'nicer' birds overall. My mom has a green cheek who is the *sweetest*, most calm, gentle parrot on the face of the planet. Barney is just a wonderful bird, but he doesn't have the same kind of 'personality' her DYH has or that my BFA has. Little zons and big zons are almost like they are totally different species. You just can't get that big, boisterous big amazon attitude in the little guys (though there are the anomalous mealies, which are the biggest zons of all, who are supposedly very mellow birds). The double yellow heads, yellow napes and blue fronts are the 3 zons with the big bodies, big attitudes and big personalities most people expect from a zon (feisty, confident and independent, but probably not very cuddly).
