Wait luzon bleeding hearts are extinct in the wild? My local zoo has them and they are listed as near threatened.
They are, as you said, Near Threatened (IUCN Red List of Threatened Species)

You two are not talking about the same species.
Though neither of which is listed as EXW.
I found several sources saying the bartletti subspecies of Mindanao Bledding-Heart is extinct in the wild. Is this not the case?
So, I just had a look into this. The subspecies bartletti is from Basilan Island and hasn't been recorded in the wild since 1925. The supposed visual differences between barletti and the nominate criniger from Mindanao are not supportable when viewed as series of specimens (see page 198 of this paper for the points of difference: https://repository.naturalis.nl/pub/210053/ZM80-05_193-202.pdf).
I find it unlikely that any captive birds are actually bartletti (from Basilan) given the length of time the captive population would have had to have been sustained - i.e at least a century with no further input - and so I think it is much more likely they are nominate criniger (or perhaps more likely a mix of criniger and leytensis) which have been assumed to be bartletti at some stage based on the supposed visual differences. That's just my own supposition of course - accurate import records would be needed.
Just as an additional point of interest, this paper gives the last records from various other islands for this species - Leyte in 1964, Samar in 1970, and Dinagat in 1972; the only post-1980 records are from Mindanao and Bohol: http://datazone.birdlife.org/userfiles/file/Species/AsRDBPDFs/species/gallcrin.pdf
Recently I saw the Extinct Roach (Simandoa conserfariam) for the first time (and even held one), so that's an EW species I've seen now, too.
however, contrary to the species' wikipedia article, this taxon has yet to be assessed by the IUCN red list, so is not 'formally' Extinct in the Wild the way the other species mentioned here are.
Wonder how long it will be before scimitar-horned oryx and Pere David's deer are reassessed, given both species have undergone reintroduction programmes that, certainly in the case of the deer, have been long-running and pretty well established by now. Anyone know more details of if the reintroduced Chinese populations are truly 'wild'?
I'd imagine the free-roaming scimitar-horned oryx population is a way off being self-sustaining yet.
I've seen both of the above, socorro dove, golden skiffia, and several of the EW species of Partula and Brugmansia. I also saw pinstripe damba while it was thought to be extinct in the wild and 2 undescribed cichlids from Lake Chilingali which *may* be extinct in the wild but, like Simandoa, have yet to be assessed. I'm also currently growing the Hawaiian lobelioid Brighamia insignis which is listed as Critically Endangered (possibly Extinct in the Wild), but the general consensus is that it is in fact gone from the wild.

So it may not be "Extinct in the Wild" but it is extinct in the wild.

I have a rather large Pere Davids deer antler propped up next to a preserved turtle about 50 cm long (60 years old plus) under an ebony table with hand carved elephants with real ivory tusks all by the coal/wood fireplace.
History. You can't get this stuff anymore and that is good. Well the antler you can if you ask nicely

I query the origin of the "extinct in the wild" status for this species. The Wikipedia page has the paragraph on its "extinction" entirely unreferenced. Everything else I see which says it is extinct is just websites selling cockroaches and such-like. The gbif page is just quoting the Wikipedia article.
I looked at the original paper describing the species. It is cave-dwelling but it is not a troglobite - it has fully-functional eyes and wings. The "cave" in which it was discovered (which the internet says has since been destroyed) was only 35 metres long and open at both ends, "allowing for a considerable amount of light to penetrate most of its area" - basically it was a water-carved tunnel containing a bat roost. The paper notes that it is unknown whether the species occurs outside caves (because it was only just discovered).
It seems extremely unlikely that the species was endemic to that 35 metre tunnel.
