you may have already come across this in your online research, but I have heard that the following things promote increased mating related hormone release in parrots:
(other forum members, please add to this list if you know of any more factors, thanks! )
-increased length of day (including the number of hours you have your electric lights on),
-increased heat (i.e. in the winter when you turn on the heat) ,
- any object in the cage or house that resembles a nest cavity, like a hut, a box, or even something the bird has discovered on its own and is fascinated with, like a cupboard,
- cuddling
- touching of feathers anywhere on body
you may have success reducing the hormonal behavior if you reduce any or all of the above factors. i know it may sound cruel to take the toy away for now, but that is what I would suggest for now. you may be able to give it back to him once his hormones have calmed down a bit, after you have reduced some of the factors in the list above.
also, once his hormones settle down, you can slowly reintroduce a scheduled short, light cuddling session, once you see him improve a little. gccs love being cuddled and i do believe they need it for their emotional well being, but at a balanced, scheduled amount. scheduled cuddling really reassures my gcc that all is well in his world. once you've got yours calmed down and mellow and nonhormonal, you can schedule some amount of cuddling that still keeps him mellow and nonhormonal.
12 hours of sleep per night in a quiet darkened room with no light source (except a nightlight) also really helps.
you are right to be concerned with his mating and hormonal behavior toward you, mainly because it is an indication of a high hormone load - which is not good for his system in the long run. but once you have been able to bring his hormone level down (it may take a couple of weeks) he will be calmer and you will be able to reintroduce his favorite toy.
hope that helped - my Gcc went through something similar to this a few years back, and I actually did what I listed above - and it worked wonders to calm him down. back then he actually went from being hyper, high strung, and interested in mating with everything to really mellow and laid back, more independent, but still playful, alert, and loving. (of course things are a little different now after his spook out six months ago, but I am still trying to stick to the list above, just to give him a stable sense of well being as he gets better. the mating hormones, my vet told me, would actually add to the spook-out stress hormones now floating around in his bloodstream to make things worse)
all the best, and let us know how it goes!
