Hi and welcome, Indian ringnecks can be loud, I know cockatiels also can be loud but as owner of two IRN I find their flock call horrible, maybe listen to it on YouTube and have a think can you imagine parrot zooming around the house and flock calling for 30 minutes constantly and you can’t do much about that because it’s kind of their natural behaviour, as my vet described ringnecks they are often high strung and it can result in problems down the way, also something to think about is that they can be independent and not necessarily keen on being handled, one of my girls is very easy to handle and in general she is easygoing, she is very social and friendly but only towards us, she doesn’t like strangers at all and takes time to get used to them, breeding season usually gets her bit crazy, still it can be managed, our other girl didn’t have best start because she arrived at ours when she was around 3 years old and we were her 4th house so she took time to adjust, she is very independent and likes to play by herself, so she has a lot of perching stations throughout the house, it works very well for her and for us because mostly she stays out of trouble ( chewing on things she shouldn’t chew) she is also very energetic also thanks to her I understand what my vet meant when he said that ringneck can bond strongly to one person, Bluey came to us with issue of not liking male humans and indeed she didn’t like my boyfriend, it wasn’t a problem because I am home more and I care for parrots most of the time, my boyfriend was aware of issue and tried to put a lot of effort into her at least tolerating him, it worked so well that last year ( so nearly after 3 years of her being in our house) she decided he is her human, my boyfriend can give her head scratches, he can touch her beak and I honestly don’t remember when was last time she bite him properly, what is most amazing he can easily put his hand inside her cage and give her scratches or clean around when she is in, when it comes to me I can forget about it, I can try but most likely I will get bitten, she is still very good with me but it’s also clear that he is her favourite, in a way it’s very sweet and makes my life easier because he used to struggle with her when I was not around but now they don’t have any problems
