I have a Green cheeked conure who seems to be extremely comfortable with me,but randomely bites extremely hard, to the point of drawing blood. He is a smart bird, and he often responds to verbal commands like step up and come here. However, he randomely bites my mother and I, and tries biting her in the face and eyes. I obviously cant have that so I need to know how to get him to stop fast or else I have to give him away. Usually when he bites, I leave him in a room or cage by himself for 5-10 minutes, or grab him firmly and loudly say "no biting" or if hes perching on me i give him a little shake. so far to take care of my bird, I clean his cage once a week or so along with all his toys, replace his water often, give him slightly cold water baths when I take a shower (mostly because he flies into them) keep him out of the cage for around 10 hours a day, and buy him shredded toys. I want to give him some harness training but i cant even get him not to bite. I often give him fruit, pellets and some greens as food, and if he catches anyone in my family eating he usually takes a bite of whatever they are eating too, and flies away. I would also like to train this behavior out of him.
