I'm not saying anyone on here is confused but I do tend to find that alot of people don't get the differences between hybrids, mutations etc.
Whilst hybrids are a cross between two species, I have to say I don't agree with this practice more than I disagree with breeding mutations. Hybrids can have health issues of course but they are usually infertile so cannot go on to pass on their dodgy mutated genes to future generations. LIke I say, I don't agree with it because there are so many endangered birds that these parrots could be used for conservation or something rather than fueling some stupid desire for the pet trade, but there are worse things. Hybrids in the wild happens sometimes, its becoming more common because numbers of certain species are declining. Unless natural genetic mutation dictates then hybrids will not take over because they are infertile (at least in most parrot species, im not sure if it applies to all of them). Things will either continue as they are with the odd hybrid appearing OR the hybrids and the original species will eventually die out.
Mutation birds are inbred to some extent, if not completely inbred, where mum has been mated to son so there is an increased chance of producing chicks with a specific look. So mum is a slightly lighter colour than a normal bird, 1 out of the 4 chicks is also a slightly lighter shade than the normal and happens to be male... the breeder likes this lighter shade so breeds them together to increase the chances of a similar coloured offspring and so on.......wayhey eventually we have a new colour, nothing wrong with that until you realise that you may have doubled the chances of getting this new colour but you have also doubled the chances of bad things like cancer, artritis etc. This is the worst examples, most probably aren't this inbred but you get the picture?
There is a reason why incest is illegal and its not because its pretty disgusting to get it on with your sibling.... The same laws should apply to all animals. Species will still change over time of course but there is no way that you will get 3 brand new colours in the space of 30 years either.
Regarding the video, I dont think it is a green cheek, it looks more similar to a pearly but not 100% on that one. I dont know if it is inbred, underweight, sick, young, deformed slightly or if it is the camera angle but I don't actually think it is a hybrid from looking at it. I'm no expert though, it might be but if you look at budgies and cockatiels bred for the pet trade these birds are actually getting smaller- particuarly the "fancy coloured birds", some I have seen lately aren't much bigger than a canary, taller but very slender/skinny looking.
