Our peer-reviewed paper is available here. Update: The production error has apparently been corrected as of 1 pm on May 19. If you’ve read the paper already, be sure to clear your history to see the corrected version. First, a shoutout to my co-authors: Tommy Michot, Peggy Shrum, Patricia Johnson, Jay Tischendorf, Mike Weeks, John […]
I’m personally indebted to David Martin (AKA Fangsheath). Not only was Dave a mentor during my early years as a searcher, Project Principalis would not exist without him. He was familiar with our study site and directed Frank Wiley to it as a promising place to search. Frank had a sighting soon thereafter. That sighting […]
An announcement from the National Aviary and Project Principalis: The National Aviary, along with Project Principalis, is delighted to announce that we have made available to the public the results to date of our search for the Ivory-billed Woodpecker. A paper titled, “Multiple lines of evidence indicate survival of the Ivory-billed Woodpecker in Louisiana” co-authored […]
Wishing everyone happy holidays and the best for 2019. While the blog has been quiet for a couple of months, the effort continues. A number of items are in the works, and I hope to have news about them in the coming months. And of course, I hope to be able to report on new […]
Regular readers are no doubt familiar with some of the images shown below. The “neck bird”, which was photographed in our old search area in August 2009, has been discussed in a number of posts. I think it likely shows a female Ivory-billed Woodpecker, something that became clearer once I satisfied myself that what appeared to […]
If you’ve been following this series (Part 1, Part 2, Part 3, Part 4, Part 5) you know it has focused primarily on preconceptions about ivorybill range and habitat types and how the actual record paints a very different picture from what many of us think we know about the Ivory-billed Woodpecker. As I noted in […]
I intended this long-delayed installment in the “Bits and Pieces” series to be the year’s final post. I also intended it to the be final installment in the series. While this may end up as the last post for 2017, I’ve decided to cut this short and save some discussion for what I anticipate will […]
Part 1. Part 2. Part 3. Bottom line upfront: In pre-contact and early colonial times and into the 19th century, Ivory-billed Woodpeckers inhabited a more varied and expansive range than most people realize. The range probably reached from the southern tip of Florida to central Ohio, with the 40th parallel as the approximate northern limit, […]
I’ve just finished reading Tanner’s dissertation and have gained some new insights into topics that have been discussed in a number of earlier posts. Conventional wisdom, following Tanner, holds that the Ivory-billed Woodpecker’s decline and possible extinction were caused by habitat loss, specifically the logging of old growth forests during the 19th and early 20th […]
Part 1 is here. Part 2 is here. At an IBWO Recovery Team meeting during 2007, a report was shared by Dr. Nathan Schiff and his colleagues at the USDA Forest Service’s Southern Hardwoods Laboratory that more formally described many of the paradoxes that have been discussed in this series of posts. It provides more […]
