Very colorful, from 6-11 inches including the tail. The sub-adults have a dark brown beak and brown irises. The beak turns red as they mature. Life span is 15 or more years, they mature at 1-2 years. A roomy cage is required unless the bird is to be let out for extended periods.
Many birds can spend most of their time on a play pen or parrot perch.
A cage guard is a good idea since their droppings are a sticky fluid which ends up outside the cage. Make sure you give them lots of toys, swings, and perches since they are very active and love to play.
