Extinction’s Yo-Yo – Ivory Woodpecker – Startled by that?


Kip Hansen news summary – April 14, 2022

The poor ivory woodpecker must have felt like a yo-yo – declared extinct, possibly extinct and almost possibly extinct and then not extinct, again and again over the past decade or so.

Here are some featured titles:

‘The Queen’ may be extinct, but the story of the ivory woodpecker isn’t over yet.”

Humans officially have KiLled out of the ivory-billed woodpecker

“Ivory-billed woodpecker (Campephilus majoris) is a possibly extinct species of woodpecker.”

Is it too early to declare the ivory woodpecker extinct?

The ivory woodpecker, along with 22 species of birds, fish, clams and other wildlife, is about to be declared extinct and removed from the endangered species list…”

“Ivory-billed Woodpecker will be officially declared Extinct in America”

And now?

Return from the dead? The Ivory-Bill Woodpecker Not Extinct: Researchers

A brand new newspaper begins this way:

“The decline history of the Ivory Woodpecker is long, complex, and controversial. The last widely accepted sighting of this species on the North American continent was 1944. Reports of the Ivory Woodpecker continue, but in 2021, the United States Fish and Wildlife Service Ky proposed declaring the species extinct. We built on 10 years of search efforts, and provided trail camera photos and drone video showing a consistent presence of Ivory Woodpeckers at our study site. we. ”

The newspaper was titled “More Evidence for Louisiana Ivory Woodpecker Survival” [.pdf] and written by Steven C. Latta, Mark A. Michaels, Don Scheifler, Thomas C. Michot Peggy L. Shrume, Patricia Johnson, Jay Tischendorf, Michael Weeks, John Trochet and Bob Ford. The authors come from a diverse collection of universities and agencies. It is not the work of a disgruntled bird enthusiast.

Their findings include:

“We believe our observations contribute to a better understanding of the twin problem as to why the Ivory Woodpecker has been so elusive and difficult to relocate for over 80 years. These problems begin with the misconception that, if at all, the Ivory bill is relatively easy to find – a misconception that stretches back to at least Tanner (in 1944)” or, as stated elsewhere. another in the article” that Ivory-bills should be loud and easy to find. ”

“The misconception about how easy it is to find the Ivory-bill extends to the frequent argument that in the modern era it is unlikely that a large, distinctive woodpecker could escape sight. , cameras and recorders, by bird watchers and others who are recreating or working outdoors in remote areas. ”

“In addition to the discovery and documentation questions, our data provide insights into how the ecology and behavior of the Ivory Woodpecker will contribute to the difficulty of finding find or rediscover this species. We know that the Ivory-bill inhabits some of the most inaccessible habitats in the United States, and that lowland mature forests are a core component of that habitat.”

And then, as with many other subjects:

“The veracity of reports from non-scientists, hunters, fishermen and rural residents who may be the most likely to access habitats such as those with Ivory-bill occupied, often dismissed. Although often interested and knowledgeable observers of their natural world, their observations of rare or unusual species are often undervalued relative to the science-based views of other species. Researchers. “

As usual, experts won’t accept factual evidence from people who most likely have good evidence.

Besides, it’s clear that Ivory-Bill doesn’t really like people and avoids them as well as densely populated areas.

Conclude:

The ivory woodpecker is not extinct – but is rare and lives in a limited number of areas of bottom forests far from humans. They don’t explode, but they don’t disappear either.

Does it really matter? In the larger scheme of things, perhaps not, there is really only one large, somewhat mysterious, species of woodpecker with a limited range.

Author’s comment:

I was very interested in the story of the Ivory bill. I like woodpeckers. My five year old grandson and I built this peanut trough for his backyard and he insisted on adding words. . . .

Thanks for reading.
