African Gray Parrot question: Lately, my bird wants to destroy my furniture and anything?

It's because it's breeding season for some birds this time around. During this time of year, some birds will become more destructive. Some will regurgitate and love on their owners while other attack them any chance they get. If it doesn't stop in by may or so, I would consult a vet, because, sometimes regurgitating for no reason is due to a crop infection.
