On the other hand, if an IBW specimen had actually been found and taken, would that anecdotal evidence be elevated as confirming that the IBW was likely found in situ and not planted as a hoax? Would it be seen in a more scientific light?
I think that a very comprehensive set of tests would be performed (then replicated and peer reviewed) to determine various facts about the specimen. Tests that would determine if the specimen was from a time period when the bird was last confirmed to exist. Are you talking about an entire carcass, or a feather, or what?
It seems that the same sort of evidence is labelled crypto woo when the species aren't found, but if they're found the same evidence is suddenly scientific. With that sort of process crypotzoology can never win, because as soon as a crypto species is confirmed as existing, it ceases to become a crypto species.
I'm not sure I understand what you are saying here.
Would finding an IBW be a win for cryptozoology? Would finding a jagaurundi be a win for it?
I would say yes on both counts (but a conditional yes on the jag). Cryptozoology champions what
folks have to say about "hidden" animals. They are primarily interested in confirming existence, not nonexistence (i.e. cryptozoologists don't run around saying that beavers probably don't exist). In some cases, these are species that are already known to exist or did previously exist. Folks have been claiming to see IBWs here and there and off and on since the last living one was confirmed. IOW, folks have been saying they weren't really extinct because
they saw one. Actually confirming that to be true would be a crypto win because people were always claiming to see something that wasn't supposed to be there. I think the jaguarundi would be conditional upon the exact circumstances and location of the confirmation. Finding a specimen in S. Texas (where they most recently were confirmed to exist) is not the same kind of win as finding one in Georgia or Florida.
But regardless, crypto wins for the IBW or the jag don't automatically transfer legitimacy to any other proposed cryptid. IOW, finding an active IBW nest in Arkansas does not mean that Bigfoot probably exists, nor does it increase the chances that BF exists. As it stands now, the recent intensive searches for the IBW have not turned up any Bigfoots in spite of folks saying they do occur there in Arkansas.
If not it would seem a strange coincidence if crypto people believed these species existed, and they turned out to actually exist. Perhaps the crypto people throw a big enough net that at least some baseless predictions turn out to be true, but I imagine there are some normal people who think the IBW exists but aren't into bigfoot or anything.
Well, cryptozoologists and cryptozoology (which is essentially a non-professional pastime or endeavor) wasn't very excited about the IBW before the rediscovery that graced the world media, and they aren't very excited about the US jaguarundi either. It's no surprise that Bigfoot is the popular cryptid. It's popularity truly dominates over whatever is the next most popular cryptid. I'm not even sure what #2 would be.
