She's definitely a pearl like Muffin, but I'm sure she has some pied in her, or maybe cinnamon. Her back/wings are like Muffin's, but she's not quite Muffin. She's Rilla birdie! I pretty sure her coloring would be pearl-pied, or maybe cinnamon-pearl, but she looks more like a pearl pied tiel to me. And her breed is cockatiel of course!
