Odd lovebird behavior?

All of this sounds normal to me. The clicking, and dancing is just him having fun and showing you affection. Birds don't growl lol, he is probably mimicking something he heard, or that is just his way of speaking. Parrots make plenty of different sounds/vocalizations. When a parrot is bobbing their head up and down in a pumping motion, it means they are about to regurgitate. This is when a bird mouth feeds their babies, or even their human companions! Another way of showing affection. As for male or female behavior, these behaviors can be seen in both es. A Dna test is the only for sure way in ing your lovebird.
