We have more than one Grey here and no problems with them bonding too much jealousy there. Pionus are gentle souls and are another African bird as are Jardines who have bright colors and can be great companions.
JARDINE'S PARROT
The Jardine's, an Amazon without the attitude. (SadieLady, a Lesser Jardine's, courtesy of Ginny's Jardine Pages.) A GENEROUSLY proportioned beak gives the Jardine's parrot an appealing, cartoonish appearance. There are three types of Jardine's, all near-identical, small green South African parrots. The Lesser Jardine's, also known as the orange-crowned parrot (Poicephalus gulielmi fantiensis), is the most commonly available in the United States. It sports a brownish-black back and wings, and orange crown, thighs and wing edges. The black-wing Jardine's (Poicephalus gulielmi gulielmi) is a slightly larger bird with a more reddish crown. The greater Jardine's, or Masai Red-headed parrot (Poicephalus gulielmi massaicus), has a smaller spot of red on the crown and broader green edging on the back feathers.
