This form of "preservation" has been discussed re a number of endangered species before. The result is simple - you are not preserving the species - just some of the genes in a modified entity.
Biological experts will be able to tell you that each species has a "magic number" this is the number of individuals required to carry all of the variants within a species. It is extremely variable from species to species. And interestingly enough humans are on the low end of the scale. This is because fast breeding non faithful short lived species have the highest number of variables - and slow breeding faithful and long lived species have the least number of variables. Each type has its strengths re the ability to survive long term.

One of the great mysteries of the bird world, but you never know what might happen, they could just pop up somewhere least expected
Thanks

Just like the night parrot, which was found dead on a fence in 2006 when it was believed to be extinct.

I live in hope..

You know actually it was rediscovered by a bloke pulling over onto the side of the road to relieve himself, and as legend tells, it was right next to his feet

Yes, that is true, but it certainly would be regarded as a 'last hope' if anything came up

I was reading a news article the other day that said scientists are going to use dna from the tassie tiger to bring it back to life so live in hope that they can do that with the Paradise Parrot.
Scientists have been looking into this for years. There is a baby Thylacine that was preserved in alcohol at the start of the 1900s and they want the dna from that to clone. All the other preserved animals have been done with formaldehyde and they can't get dna from them.

Even if they do clone the Thylacine, it won't last long in the wild or captivity due to lack of genetic variation. Any animals they make would all be genetically identical and this would lead to inbreeding and a gradual decline in numbers before extinction hits them again.

As a general rule, you need at least 20 unrelated pairs (40 unrelated animals) to have sufficient genetic diversity to keep a species going. And most animals do better if they have at least 200 unrelated animals, especially if they are released into the wild. Anything less than that increases the risk of related individuals hooking up and producing young.

Agreed, even the fetus in the jar has bad DNA sequences or something like that, that was only fixed only last year i believe

Anything less than that increases the risk of related individuals hooking up and producing young.
And the world is full of people who will tell you that related creatures should not hook up. Yes it seems icky to us. But birds and animals do not have this taboo, and neither did many past human societies. Genetically healthy creatures that are siblings will not produce faulty babies. Totally unrelated creatures with a faulty gene of the same type will produce faulty babies. Yes - it is more common for faulty genes to show up in related pairings - e.g. the european royals with hemophylia. But the Hyacinth Macaw is being bought back from extinction with a very limited gene pool. Lets all work for genetic diversity, but not condem the reality of limited gene pools.

Well said Finch Breeder
It's all about proper practices and careful selection

Came across an interesting article in an old ABK mag the other day
Written by Phil Digney in his article series 'In search of Paradise', claims that they were still around even in the late 1950's, on a few extremely large cattle propertys in Central QLD
Here's Hoping

If they did exist, that would be the likeliest location. Out the back of nowhere where the cockies know how to keep quiet.
