My learner-style drawing aside, if you're wondering why this bird is a parrot, (also known as a psittacine), here are the three major characteristics:

* long tail feathers that hang significantly past the body. Note: not all systems include this characteristic.

* curved beak with the hook extending over the bottom half. There's a bit more to this, but it's too long to go into.

* two toes pointing forward, two toes pointing back. (This is hard to see in my rendering.)

Common parrots: budgerigars (parakeets); cockatoos; African Greys; and lovebirds (peach faces).
