Unfortunately inbreeding does happen with most animals, in the wild this isn't a problem, it may cause a small problem but that problem ends pretty quickly as usually inbreeding causes inferior, weaker animals which usually die before they get chance to breed themselves so the species gets stronger as a whole. So a little problem stays a little problem.
In captivity humans actively encourage inbreeding, this isn't a massive problem to start with but it quickly becomes a massive problem because babies with bad genes that would get killed off in the wild are actually surviving because we give them heat if they are born with a thinner coat, we protect them by keeping them away from the predators that would catch an animal with a dodgy leg etc. But then we breed them because we "like" the way the thin coat looks or the way the leg has a funny bend in it so then it passes on even more badly mutated genes.
Look at racehorses, they have genetic issues of course they do because they have been inbred too, but they have been bred for their strongest points so they suffer much less genetic disorders than dogs which have been specifically bred for looks. The pug has about 8 different genetic disorders alone, if not more and that is just 1 breed.......because it looks cute with its scrunched up nose and corkscrew tail (apparently, I disagree with that one). The UK kennel club had to set regulations stating that mothers and sons cannot mate, brother and sister cannot mate etc. I would bet on it that it still goes on though. Dogs are being bred even though they have known health issues.
Now we are breeding parrots for looks and of course money too, the budgies and 'tiels and getting smaller and less able to fight infection, I don't think there is a massive problem yet but there soon will be. Other parrots are getting bred for colour now too, the further away a bird is from its natural colour, the more it is almost guarenteed that alot of inbreeding has gone on. Blue quaker parrots will be less inbred than the lutinos for example but guess which one sells for the most money? it isn't the blue thats for sure.
Like I say I dont think there is a major problem yet like there is with dogs but if you seriously think that there isn't any inbreeding going on I would think again.
Knowing what I know now, I would never buy any bird that has deliberetly been bred for its looks. I do have a yellowsided green cheek conure from a breeder but nearly 3 years ago I was alot more ignorant to what goes on than I am now.
