What is the Difference Between Cockatoo and Parrot?

Cockatoos and parrots are both types of birds belonging to the Psittaciformes order, but they belong to different families and have distinct characteristics. Here are some key differences between cockatoos and parrots:

1. Feathers: Cockatoos have unique crest feathers on top of their heads that are moveable, while parrots do not. Cockatoos also have predominantly black or white plumage with hints of red, pink, or yellow, while parrots mostly have green plumage with hints of the same colors.
2. Anatomy: Unlike "true" parrot species, cockatoos have a gallbladder and do not have oil glands that facilitate preening.
3. Behavior: Cockatoos are known for their loud and grating calls, which serve various purposes, such as identifying flock members, warning of danger, and expressing emotions. Cockatoos are also more prone to behavioral problems like aggression, biting, feather destruction, and self-mutilation.
4. Intelligence: While cockatoos are not known for their talking skills, they are good at learning tricks and are fond of music and dancing.
5. Size: Parrots come in various sizes, from the tiny pygmy parrot to the large macaw, while cockatoos are medium to large-sized birds.
6. Diet: Cockatoos prefer fruits and vegetables as their main food, while parrots have a more diverse diet.

In summary, cockatoos and parrots differ in their feathers, anatomy, behavior, intelligence, size, and diet. While they share some similarities, such as their ability to imitate human speech, they have distinct characteristics that set them apart.
