Party Parrot is tired after a hard day of partying
Aww yiss, head scratches
Parrot head scratches
My mom's parrot (who is like 35 now) will scratch his own neck as a hint that he wants you to help him out a little. He's not very subtle. He will also dunk his head in his water dish when he wants a "shower" (i.e. getting sprayed with a squirt bottle as he rotates and spreads his wings and then gets dried with a blow drier, singing and whistling all the while).
