Blue Fronted Amazon Parrot (Camp Verde)

Rehoming a Blue Fronted Amazon parrot.
Much personality.
Age unknown, but somewhere between 15-20.
He is very quiet.
He will let me scratch his head when he is inside his cage.
He likes to come out of his cage, and he will go back on his own.
He will even stay around his open cage in the yard, and he will step up on my arm and let me put him back in his cage.
BUT I USE GLOVES because he will bite.
His "tell" is his fear of the stick.
Rehoming fee $600.
