The upper mandible is quite mobile and provides great leverage.
Parrots are among the noisiest of birds.
The majority eat seeds and fruits. Most of them are sociable and gregarious. They have a thick, flexible tongue which allows them to shell and eat even the tiniest of seeds. Most species nest in tree cavities and may roost communally. They have feet in which the two outer toes point backwards and grip in opposition to the two forward pointing inner toes.
