I have a bird that hates coming out of the saftety of her cage. Every Sunday I have to clean the cage and coax Sweety out. She always bites me once and then settles down for a grooming. She never breaks my skin, but that's just our routine. She's the only one in the household that appreciates how I like to whistle and her favorite song is Patience by Guns n Roses -- she's cool like that.
