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 […]
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 […]
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. […]
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, […]
Part 1 is here. Part 2 is here. It looks like this series will end up being a five-parter. Part 4 should follow later this week and Part 5 sometime thereafter. Most of us with an interest in the ivorybill have internalized a set of beliefs about what constitutes “suitable” habitat. To a large extent […]
Update and correction: Since writing this post, I have sought additional information, and it appears that the record was due to a miscommunication (not an erroneous report or false claim). It turns out it was retracted as pertaining to Pileated Woodpecker a few years later (T. Labedz, pers. comm.). Pileated Woodpeckers were extirpated in Nebraska […]
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 had been planning to do a post with various ivorybill related tidbits in anticipation of the search season, which begins next month. That will be coming in a week or so, but I want to say a little more about Bill Pulliam first (beyond his Luneau video analyses, which I think should be dispositive). This […]
I just received the sad news that Bill Pulliam recently and suddenly succumbed to lung cancer that was caught too late. I never met Bill but corresponded with him and got his input from time to time. I respected and admired him immensely. As long time readers know, I think his analyses of the Luneau […]
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 […]
