This is hilarious because that's my nanday hybrid's favorite line too! I found that my boy's more likely to quiet down if I've spent an hour and a half playing with him nonstop. I think he gets tired of me after a while and moves on to more interesting things. I also make sure he has lots of things to play with when he's in his cage. Boredom can lead to bad habits
Since you have a nanday I have a question.. Does your "hump" things?? Mine does all the time and I don't know what to do about it.
No, I've never had that problem. Do you for sure know the sex of your nanday? Because I think the humping action you're asking about is more normal for a female conure. If it's for sure a male and you want to train this behavior out, when he goes to hump, redirect his attention with a toy or a trick he already knows. If his humping is focused on a particular toy, remove it as soon as possible. Watch what starts the humping so you can cut him off before it happens and train it out.
