I have an african grey- not the same species, but it is of around the same size so I sympathise about the biting. Any parrot takes a fair while to get used to their new owner- it's not really a baby either as it's approaching the 'brat' stage which is equivalent to the 'terrible twos'! Birds can get pecky during this phase which is equivalent to puberty. Patience will be the best way- most parrots generally aren't vindictive and they'll bite as a defensive mechanism. However a small percentage of birds are biters that bite for the heck of it. You'll need to establish under what conditions your bird bites in order to determine this. Is the bird only biting when approached, or is it actively seeking to bite? You can try a few psychological tricks on the parrot. Firstly, lower the cage as a dominant bird will naturally go higher than its subordinates. Lowering the bird tells it that it has a place in the pecking order and it's below you. Then entice it out of the cage. The cage is the bird's territory and if the bird is unfamiliar with you, it will defend its cage and itself. A small t-perch is ideal for this, or a small parrot table-top gym which are available from pet shops for around the £30 mark. It's a good investment as the more time the parrot spends with you, the more confident it will become. Next it will be a case of gently and slowly introducing yourself to the bird and showing it that you and your hand is no threat. Expect to get bitten during this phase. The bird does not know you and will peck to establish itself- 'pecking order' is where the phrase comes from. Make slow deliberate moves- preferably after sitting near the parrot for a while so it gets used to your presence. If it goes to bite,do not back down, instead give a firm command. I used 'Step Up' or 'Up' to signal to my bird that I was boss. Don't put it back into the cage in its comfort zone if it bites. If my bird is on my hand and goes to peck, I will shake the hand lightly or drop it. This destabilises the bird and they will let go. They soon get the picture that biting= a scary drop and link the two. My parrot doesn't particularly get on well with my husband- however he's gotten around the biting problem by wrapping a hand towel round his hand and getting the bird to 'step up' onto that. If he bites, hubby doesn't feel it and doesn't back down in front of the bird. All parrots will bite at some point. Even my bird who is pretty docile will chuck a strop (usually when it's time for bed!) and sometimes peck. He gets a strong 'bad bird' command and is placed back onto his play perch and ignored for 10 minutes. As he's a very social bird, ignoring him works. They may also peck unintentionally- the tongue is a tool they use to explore- they may test with their beak as to whether a perch, arm or hand is safe enough to step onto and can sometimes test too hard. I've developed an 'ouch' signal for my parrot if this is the case. I say 'ouch' and he releases my finger and repeats 'ouch' back to me. Lastly, bear in mind that the parrot's history is unknown to you. As it is already a year old, it may already have some negative experiences or feel very unsettled by the change. It may also need time to bond with you, the new owner as it bonded with its old owner. Be patient, persistant and confident. It will get there eventually.
