The great-billed parrot has an enormous beak (hence the name); however, they do not use their beaks for biting — they are known to be gentle parrots. They need a lot of things to chew on to exercise their beak, though. Although they are more reserved by nature, they might allow their owners to give them a kiss on the beak or back, or to gently stroke their feathers. They tend to want to be where their owners are, and enjoy time out with the family.
Great-billed parrots are known to be great eaters - their digestive systems are good at absorbing all of the nutrition from their food. Pelleted diets can be too rich for them and they have problems with over nutrition. They do well on a diet of fresh vegetables, fruit, cooked or sprouted grains and beans, as well as seed mix and nuts, but confirm with your avian veterinarian on the best diet for your great-billed parrot. Although great bills are generally quiet, they can be loud when excited and during breeding season. Because their large beaks can be destructive to objects around them, it is important to keep close watch on them when they are out of the cage and to provide them with sufficient branches and toys to chew when they are inside of the cage.
