Thanks for your advice, I think a trip to the vet is definitely on the cards. His behaviour is becoming worse and worse since taking the legs off my couch. He regurgitates on EVERYTHING! He is constantly following my feet and tries to mate with them, he will regurgitate on my shoes, on my carpets. I literally have to hide absolutely everything. I've removed toys from his cage which he can shred and turn into nesting material. And even then, when I put him in his cage and cover it over night I can hear him regurgitating into one of his bowls. Its getting out of control now and he is becoming increasingly aggressive. I'm not sure how much more of this behaviour I can take. I am very confused though, because it is coming into winter here in Australia, the days are much much shorter. Not sure why this is happening now
There is more to birds hormones than just the outside weather/time of year. Diet, interactions and environment can also be triggers for hormones.
I wont remove everything my bird wants to regurgitate to, as long as it is his, he can do what he likes with it, it is not helpful to remove everything and is likely only going to increase frustrations which equals more unpleasant behaviour so I tend to leave the things that are his as long as he is not so obsessed with feeding them that he does nothing else, he has broken bits of blocks and other foot toys he likes to feed so I leave them for him but totally stopped him trying to feed me and my hands.
I can sympathise with you over the difficulty of dealing with aggressive behaviour
I hope your little guy settles soon.
Just curious if you have tried mixing up the cage accessories, placement of cage or even rearranging the whole room your bird is in- it sometimes helps to clam the nesting behaviour.
