2023 in Retrospect (Part 1) and a Little About the Future
December 20, 2023
It’s difficult to write about such an eventful year, so it seems best to tackle it in a series of posts. The publication of our paper was, of course, a major milestone, as was the Fish and Wildlife Service’s non-decision decision on delisting. The latter had deep personal significance, not least because my 2018 submission…

Final Installment: Trail Cam Deployment and Pileated Woodpecker Hits April-October 2018.
November 1, 2018
I’ve completed reviewing the cards from the deployment discussed in three previous posts. As it turned out, the most dramatic and informative sequence was captured on July 29; it was the last sequence found in the course of the review. To recapitulate: the tree is a hickory, and hickory bark is uniquely tough, tight, and hard…

Updated with More Pileated Woodpecker Clips: Trail Cam Results and More on a Camera Trap Tree
October 29, 2018
The original post from last week is below the updated material. It provides some important background, and I encourage you to read all the way and watch the clips. A couple of prefatory notes for new readers: first, this discussion pertains to hickories only because the bark of trees in the genus Carya has characteristics that…

Trail Cam Results and More on a Camera Trap Tree
October 26, 2018
I just returned from Louisiana where I visited both the search area and the location of Joseph Saucier’s sighting last year. There were no possible encounters on this trip and just a little of potential significance ivorybill-wise. I plan to post a trip report within in the next week or so and hope to get…

Evidence: Project Coyote 2009-2018
June 29, 2018
Summary Evidence collected by Project Coyote in two parts of Louisiana from 2009-2018 should, on its own, suffice to justify maintaining the Ivory-billed Woodpecker’s current listing as an extant, endangered species in the United States. Others may differ, but I think the totality of the evidence does even more, making a compelling case that the…

March 21, 2018
Back in the early 2000’s, I often used the holiday break as a time to take off from work and go birding someplace I’d never been before. Following the Ivorybill rediscovery announcement in May 2005, I decided to go to Arkansas “on a lark” and at least see the habitat where the bird had been…

What’s in the Cavity? A Possible Second Bird in a Couple of Old Trail Cam Photos
January 23, 2018
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…

January 8, 2018
I returned to the main Project Coyote search area where I spent December 27-January 1. I was joined by two new team members – Erik Hendrickson, an excellent birder and retired National Park Service engineer who had an ivorybill sighting in Arkansas back in 2005, and Jay Tischendorf, a veterinarian with a long and adventure-filled…

Change of Pace, Change of Place: Trip Report and Sighting Follow-Up, November 16-21, 2017
November 28, 2017
On October 22nd, I received an email reporting a recent ivorybill sighting in eastern Louisiana. I found the report convincing for its high level of detail and decided to devote my next trip to following up on it. The source was Joseph Tyler Saucier, a pastor, avid hunter, and Louisiana native whom I’ve known virtually…
