I''ve a couple of questions which I hope someone can provide some advice on, with regards to "biting" and "unprovoked attacks" from my IRN.
I've a Blue IRN (Male), and he's about 4 years old (born around Oct 2004). Whilst I do notice that it may seem that's it the mating season now (seen from the fact that my IRN does this "mating" dance in/around his cage, and also displays it to my Cockatiel (also a male) and that the hormones may be affecting his behaviour, he seems to (sometimes) get into this mood of biting and attacking my wife whenever she's around or in the same room. This seem to happen a lot near where his cage is located - my wife could be at the opposite ends of the room yet my IRN would fly to her, and stated biting and attacking her and would let go - she's suffered a few wounds as a result

Could that be due to him being in the mating season, and that his hormones playing a part, or could that point to some (other unknown) problems?
Any advice would be appreciated.
Thanks.
