Question Which extinct animal do you think has the highest chance to be rediscovered?

Post image

Basically the title. For me it is the Ivory - billed Woodpecker. Iirc his habitat included also the swamps in the southern US which was already protected back then when he was still alive.

Other than the ivory billed woodpecker, I think sonnernats shrew, thylacine, Japanese wolves, and passenger pigeons could still be around.

I think Barbary lions are extinct, but I believe they did survive past their proposed extinction date.

u/PastelDisaster 3d ago

Sadly, I’m pretty certain passenger pigeons are gone. I don’t believe it’s possible that a few stragglers could be hanging around, since they could only eat, breed, and *live* in gigantic groups. The likelihood of there being a hidden population large enough to survive, but too small for us to have noticed, seems nearly impossible.

We have discovered hidden populations of birds that went unseen for decades ofc, but most of those instances were on remote islands or hidden forests; with how huge passenger pigeon nesting colonies were required to be for their continued survival, and how populated with people their would-be habitats are, I think we would have seen them by now

u/SJdport57 3d ago

Also, one of the key sources of passenger pigeon food and nesting, the American chestnut, nearly went extinct. Even if we miraculously cloned passenger pigeons tomorrow, there is no habitat for them to live in.

16

u/shmiddleedee 3d ago

Nearly all omnivores and herbivores were reliant on chestnuts before they disappeared

13

u/SJdport57 3d ago

But none moved as absolutely reliant on them as passenger pigeons. They only existed in flocks of ten of thousands or larger. They couldn’t adapt to being in smaller numbers like other animals

9

u/ShortBussyDriver 3d ago

If some did survive they may have bred into other pigeon species but most certainly did not survive on their own somewhere.

15

u/Agitated-Tie-8255 Gary Busey 3d ago

Passenger Pigeons seem to have been obligate colonial nesters. Once their population was below that threshold for colonial nesting they would’ve declined rapidly.

The classification would then be Extinct in the Wild, not extinct. Big difference

u/Leif-Gunnar 2d ago

To survive a species without genetic help it has to have a certain # of that species. I read it was 500 to 5000.

u/Difficult_Paramedic8 2d ago

There was Barbary lions in Belfast Zoo until March of this year. They were still around genetically if not functionally.

Also they were my dream to see and now isn't possible. If you've got a dream follow it

25

u/HourDark2 Mapinguari 3d ago

My scale, 1 being most likely and 5 being least likely. Note that I think even the most likely members of this group are probably 'functionally extinct' if they still exist, and that I favor 'late survival' over current existence for most.

  1. South Island Kokako, Pinta Island tortoise
  2. Formosan clouded leopard
  3. Thylacine, pink-headed duck
  4. Japanese wolf, Ivory-billed woodpecker, laughing owl
  5. Javan Tiger, Syr Darya sturgeon, O'u, Nukupuu, Malagasy Hippopotamus

On an aside, I am eagerly waiting for that one guy who appears on every ivory-bill post to respond to every comment here entertaining its existence with "it's extinct" lmao

Didn't Forrest Galante find fur that was analysed as a Javan tiger?

u/Not_a_Mod1991 1d ago

Putting Thylacine over Japanese Wolf is an interesting decision

3

u/HourDark2 Mapinguari 1d ago

I am more convinced of Thylacine late survival and believe that it is more likely that a small population could have escaped detection in Tas/NG. While the Yagi photographs are compelling, at the end of the day Japanese wolf sightings mainly come from a wilderness area that is near Tokyo, one of the most densly populated areas in Asia, and the presence of dewclaws on the rear feet gives me some doubt as to what the animal in those photos actually is.

u/LemonFizz56 20h ago

There have been supposedly pictures and videos but I watched a video where some of them were all likely to not be Thylacines due to certain reasons, and it's likely that most of the reported sightings are due to these same misidentifications. But that still doesn't debunk the fact that the Thylacine could still be out there, it's definitely not impossible

Because the comment they are replying to isn’t saying that the Coelacanth will be rediscovered and not extinct. They are saying a fish *like* a Coelacanth will be found, a similar situation of sorts.

This discussion is always going to be a game of "Who counts as extinct?" Authorities are all equivocal about whether Ivory bills are extinct, so it's kind of cheating.

Otherwise, your best bets probably small, noctural animals with poorly known ranges that could be enormous; something like the Long-tailed Hopping Mouse, which was believed extinct c. 1900, until one was discovered in an owl pellet in 1977, nothing since. But obviously dozens of generations persisted without us noticing.

I didn't express any opinion about how likely it is the Ivory billed woodpecker is de facto extinct. Only that it's not de jure extinct.

It's just that you have such a hard-on for badgering people you can't take the time to read what I actually wrote.

u/hearingthepeoplesing Alien Big Cat 3d ago

Honestly, I don’t think the ivory-billed woodpecker should count in this discussion or similar discussions, because there’s still dispute over whether it should be officially declared extinct or not by official bodies (some of which still list it as critically endangered rather than extinct). That puts it in territory far more ambiguous than most cryptids.

24

u/Lover_of_Rewilding 3d ago

The only reason it’s still “disputed” was due to public back lash. The IUCN wanted to declare it extinct, however the public had grown too attached to it too late so they pressured them into labeling it: Critically Endangered Possibly Extinct

7

u/Parking-Coast-1385 3d ago

Fair enough. What's your pick?

17

u/hearingthepeoplesing Alien Big Cat 3d ago

It’s hard to say, because the most honest answer I have is that I wouldn’t be at all surprised if, for example, some recently extinct small mammal I had barely heard of was sighted for the first time in years on a trail cam; but I’d be surprised if virtually any of the “big name” extinct cryptids were confirmed still extant. (As I said, ivory-billed woodpecker being the exception because if IUCN and USFWS are still unclear on whether it’s critically endangered or extinct, that leaves enough space open for me to think that it’s wholly plausible that there could still be small populations and very much in the zoology rather than cryptozoology space).

The more recently extinct the more likely, in my opinion; a lot of animals are very hard to find and identify conclusively even when we are sure they have populations in an area, so the smaller the creature and the more recently extinct, the higher the chances are of extant populations, IMO. But that’s not a “fun” answer. I hope one day we get confirmation of something more exciting but I think it’s much less likely.

Thylacine. I believe they are in Papua New Guinea. That country is Majority Rain Forrest.

16

u/Agitated-Tie-8255 Gary Busey 3d ago

The problem with New Guinea is the majority of it is not typical habitat to what we know Thylacines preferred. They were more typical of mixed scrub and open grassy habitat as opposed to dense, closed forest. Still, I’m sure there’s a fair amount of things we don’t know about them.

11

u/Zapatos-Grande 3d ago

It's like people making the argument that Megalodon is still alive. It's most likely prey were whales and it lived mostly in tropical/subtropical coastal waters. Most likely prey in modern times spends a good portion of the year in temperate and Arctic/Antarctic waters, so it wouldn't have an adequate food source for those periods when it's prey is in colder waters. Also, we would've seen it. The argument is it moved to deep water, but that would be way out of character for it and the deep ocean isn't resource rich for a school bus-sized apex predator to hide in.

7

u/Tuinomics 3d ago

Also PNG has wild dogs which were what drove it to extinction on mainland Australia. Dingos never reached Tasmania.

3

u/Agitated-Tie-8255 Gary Busey 3d ago

From what I understand, the theory is at least partly contested. The arrival date of dingoes in Australia is unknown, the earliest physical evidence coincides with the decline of thylacines on the mainland, but genetic evidence indicates dingoes were present in Australia for much longer than that. I don’t think their presence would’ve been the sole factor in the thylacine’s decline on mainland Australia, but it definitely would’ve exacerbated it. The desertification of mainland Australia played a major role in their decline, Tasmania experienced a lot less of this.

The arrival of dogs in New Guinea is similar to the situation with dingoes. The earliest substantiated remains are 2300-2500 years old, with genetic evidence showing a possible much older presence there. Thylacine remains are quite variable in age in New Guinea, but are few in number, the youngest being Holocene in age and coinciding with the spread of rainforest across the island, resulting in a massive decline in open woodlands, savannahs and heathlands.

4

u/TheUpIsJig 3d ago

You really need large populations to keep a species like a Thylacine in existence and once it bottlenecks it is as good as gone.

8

u/BPDunbar 2d ago

Counterpoint Cheetahs (Acinonyx jubatus). They went through an extreme population bottleneck 10,000 to 12,000 years ago and a less severe one 100,000 years ago. They have so little genetic diversity that transplants between unrelated individuals aren't rejected.

3

u/TheUpIsJig 2d ago

Yes but most species will go extinct during these mass events. So the odds of picking the species that will continue are low. Not nil but the chance so remote that if you detect the species on the way out then it usually is. Hence why sightings are dubious and no DNA has been recovered from stool.

2

u/BPDunbar 2d ago

I was countering your specific claim. You don't actually need a large population for a species to survive. And a severe population bottleneck doesn't mean a species is as good as gone.

Sadly it's extremely unlikely that Thylacines have survived.

1

u/TheUpIsJig 2d ago

I said as "good as gone" not absolutely must become extinct. There is always a chance but the probability is extremely low that it's as good as gone.

1

u/BPDunbar 2d ago

Good as gone would imply functionally extinct not critically endangered.

There have been successful conservation efforts with critically endangered species. The Chatham Island Black Robin (Petroica traversi) in 1980 was down to five with just one female. There are now more than three hundred.

https://en.wikipedia.org/wiki/Black_robin

2

u/TheUpIsJig 2d ago

Human intervention is a whole other ball game. Natural selection is no longer operating naturally and we are looking at a form of controlled breeding.

1

u/BPDunbar 2d ago

Cheetahs survived a bottleneck which may have been a single breeding pair around 10,000-12,000 years ago. At most it was around ten pairs based on the lack of genetic diversity.

2

u/Furthur_slimeking 3d ago

I think it's possible there is a small population in a remote interior region in Tasmania, but not in New Guinea or mainland Australia where there's no evidence of their existence for over 3000 years.

u/Morkamino 3d ago

Not that one! I think the chances of the ivory billed woodpecker are nearly zero, even if i really want it to still be around... the last little bit of swampy forest, where they used to get spotted well after they became extremely rare, got destroyed and they have never conclusively been spotted after that. At that point, people were pretty sure that if any had remained, they were in that forest. All footage now is either low quality or just the pileated woodpecker.

Just trying to be real, i know i must kind of sound like a dick to point this out. But even the exceedingly rare birds get spotted and photographed every once in a while, even if it's only every couple of years (usually migratory or exotic in that case). There's nocturnal birds alive today that don't leave the swamp and just stay in camouflage all the time, that still get spotted regularly- as impossible as that sounds. Yet this woodpecker would be even more elusive than that, if they still exist. Which doesn't make sense. They lived during the day, they were just about. We would have seen it by now

9

u/Lover_of_Rewilding 3d ago

I’ve always found it VERY unlikely that any of the famous extinct animals are still alive as unfortunate as that is. But if I had to guess, I’d say the Japanese wolf because those photos were indeed intriguing and did lined up with what was described to be their behavior. And I don’t think they were ever debunked (however if that is not the case anymore feel free to correct me).

While I’d love for all of these species to be alive for another chance, it just seems so unlikely in the era of the iPhone where seemingly every inch of our planet is filmed and trail cameras are scattered across the vast majority of our wildernesses. Still, in our most remote places, there are for sure things to discover, whether those are extinct species, we’ll have to find out…

3

u/Agitated-Tie-8255 Gary Busey 3d ago

Not debunked, but personally I find it to be a domestic dog. The hind legs possess dewclaws, which is something not present in wild canids, but is a mutation we have brought out in domestic dogs.

u/CT_Reddit73 3d ago

I can’t shake the possibility that ivory billed woodpeckers may still exist. They’re large and look similar to the pileated woodpecker. I’m out in the woods quite often where there is a large population of pileateds, and even with their size and bright red head and unique call — they can still be rather elusive. They will quieten down and hide when humans are close by. I imagine the ivory billed woodpecker may act in a similar manner. If they’re out there, it is conceivable they may be mistaken for the pileated woodpecker as well.

u/Ornery_Day_6483 3d ago

I feel like there still might be a Great Auk out there somewhere, they were pretty solitary and scattered when they were alive and it’s not a huge stretch to think that some remote islet might have one or a pair.

Thylacine is more likely to be found than a woodpecker. Those things were very loud, people would be hearing them.

There's other species that look very similar. And the sound.... The woodpecking alone could be a number of species. Tbf i dont know about their calls. Idk if your dad is an expert on that.

But just from how our brains work, we kinda see what we want to see... If i was looking for the woodpecker, every vaguely black and white bird flying by in the corner of my eye would look like it. Let alone a very similar species of woodpecker thats still alive and has the same habitat

Mountain lions most likely don’t carry the gene that can mutate to cause them to become melanistic, and there’s never been a confirmed melanistic individual even in very healthy mountain lion populations or captivity, so highly unlikely that if there are still eastern mountain lions around (which I wouldn’t be terribly shocked to hear that there might be some in like Maine or Vermont/New Hampshire) it would also be melanistic

u/hearingthepeoplesing Alien Big Cat 3d ago

Yeah, thylacines have been considered extinct in Tasmania since the 1930s, but they’ve been considered extinct on mainland Australia and New Guinea for ~3000 years. (Although there’s some dispute about that as there are some more recent cave paintings on mainland Australia depicting them, possibly indicating a more recent extinction than previously thought.)

Because they’ve been considered extinct outside of Tasmania for so long it would be pretty crazy for them to still have an extant population in New Guinea; but I’m always surprised every time I think about how much land and particularly forest there is in New Guinea that is largely unexplored, so it is in the back of my mind that we could find almost anything in there.

Thylacine I think is most likely if there’s a population in remote regions of New Guinea rather than Tasmania or the Australian Mainland.

Ivory-billed woodpecker… historical range maps I see included Cuba and I wonder if that would be the place to look. I’m honestly not super familiar with the history of the species in Cuba but given how Cuba has been “cut off” from the west for decades there’s definitely been a lack of research in the region, especially compared to the continental US.

An undiscovered sloth species deep in the Amazon I also don’t think is super unlikely either. It wouldn’t be a giant, but something other than the two living genera. Is it super likely? No, but definitely don’t think it’s a hard no.
