Sadly, not much (effectively-none) evidence has been found this past season supporting the birds’ existence (the link in post 3 above is 3 years old). Plenty of sight records but no photos or films. This of course provides fodder for a certain brand of skeptic who likes to crow, “I told you so!”, but you have to wonder why, during all of these sightings, not one person thought to snap a picture. I get the impression that there weren’t many hotshot pro photographers combing the woods, rather a bunch of amateur birders, with a decent set of binoculars if they were lucky. Now the birds’ purported existence isn’t stopping a certain private group from building an airport near one of the “hot spots” in NW Florida. I personally still have hope

It’s certainly not a matter of no one “thinking to snap a picture.” Birds can be very difficult to get a photo of, since even if they are close enough so you can see them clearly through binoculars they don’t take up much space on the frame and also are apt to move suddenly before you can take a shot. The teams looking for these birds are equipped with cameras, but haven’t been lucky enough to get a convincing photo yet. And they are far from a “bunch of amateur birders;” they include highly experienced professional ornithologists as well as non-professionals with a lot of birding experience.
As I’ve said before, it is my considered opinion as an ornithologist and a birder that Ivorybills still exist in the US. I am the chair of the Panama bird records committee, and we regularly evaluate sight records by birders. In my opinion, the details accompanying both the Arkansas and Florida reports are sufficiently detailed, the fieldmarks observed sufficiently unequivocal, and the observers sufficiently experienced to make the records credible even in the absence of photographic evidence. There is also the matter of recordings obtained in both areas, which are consistent with calls of Ivorybills (and, in my opinion, unlikely to be those of other birds such as Blue Jays). But some ornithologists won’t accept anything short of a clear photo or other unequivocal evidence in order to accept the records. It’s a bit of a Catch-22: Ivorybills are believed to be extinct because of the lack of confirmed records; but sight records that would be acceptable for other rare species are not accepted because the species is supposed to be extinct.
At this point, the best evidence is coming from the north Florida locality. There actually seems to be a population there, and there have been repeated sightings and many recordings have been made. The Arkansas records are more equivocal, because there seem to have been no more sightings from that area. I believe that the original records were authentic, but the bird(s) have since moved away (or died). There probably is a population somewhere in Arkansas, but it hasn’t been located yet. Based on a record some years ago that I and many others found credible, there may be a population in Louisiana as well.
As to the question in the OP, it’s impossible to evaluate due to the lack of detailed information in the linked article. I don’t know how the proposed funding is to be allocated, and how much is going to the searches and how much to habitat protection. So I really don’t know what the “real” costs of the hunt itself may be. And efforts to protect habitat will benefit many other species as well.
However, even the figure of $27 million should be put in perspective. The most expensive paintings sell for upwards of $100 million, and a single fighter jet may cost upwards of $40 million. Yet, unlike these things, the Ivorybill is irreplaceable* - once it’s gone, it’s gone forever. Considering this, to me at least it doesn’t seem to be out of line.
*While the original of a painting is irreplaceable, copies can be made that would be indistinguishable to the average observer.
