Exchanges with Chuck Hunter in a private Facebook group and in conversation inspired this addendum. If you haven’t read the original post, 2023 in Retrospect (Part 4): Acoustic Data in a Visual World, I encourage you to check it out first. Chuck’s comments led me to reconsider Tanner’s response to the Dennis recording, which resembles […]
Introduction While I didn’t fully apprehend it at the time, the events that took place over several days in mid-March 2017 were singular. Crucially, the set of recordings made by Matt Courtman (formerly affiliated with Project Coyote) and Phil Vanbergen is unique in the history of ivorybill searches. Project Principalis’s paper included a discussion of […]
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 […]
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 […]
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 […]
The first trip of the season was relatively uneventful, although we heard possible single and double knocks on Thursday morning and afternoon. Unusually heavy hunting activity and bad weather kept us out of the field on Saturday the 22nd and most of the Sunday the 23rd. Peggy Rardin Shrum joined me from Tuesday through Friday. […]
I’ve been reviewing copies of Louisiana Conservationist (formerly Louisiana Conservation Review), the official publication of the Louisiana Department of Wildlife and Fisheries (formerly the Department of Conservation). Copies of the magazine, which is in the public domain, can be found in the Louisiana Digital Library. In the course of my research, I found one real […]
I’m reposting an entry from February 2015 with some new commentary as prologue. I recently received a Google alert about a new paper on statistical approaches to extinction relying on sight records. According to the paper, which has not yet been peer reviewed: We have shown that the rate of sightings is the strongest indicator […]
Just over a year ago, I quoted at length from a 1949 letter to Tanner from Arthur MacMurray (a former student). I’m reposting that transcript below and have some additional commentary. Eckelberry’s famous “last” John’s Bayou sighting in April 1944 has become a legend, even though Peterson, writing in 1948, had the lone female remaining […]
On March 15, Phil Vanbergen and Matt Courtman recorded numerous kent-like calls at the same location where we heard several calls on March 11 and 12. Phil was able to record two of the March 11 calls. That capture is included in the post, along with Phil’s audio from the morning of the 15th. I […]
