A Tantalizing Trail Cam Capture

Best laid plans . . . I’m pushing back the posts on historic range and evidence but hope to get to them soon. In going through some of the remaining unexamined images from past trail cam deployments, Geoffrey McMullan came across an intriguing image. He sent me the file for the entire day without indicating […]

Repost with Addendum: Ivory-billed Woodpecker Sightings and Evidence 1944-2003: The Partially Hidden History

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.

I thought I’d address a couple of comments from ibwo.net written in response to the recent post on sightings and evidence from 1944-2003. Duck Stamp reminded me that Lewis’s story and identity were revealed in Tim Gallagher’s The Grail Bird, and Houston pointed out John Fitzpatrick’s discussion of the images in a presentation on the rediscovery. As far […]

Ivory-billed Woodpecker Sightings and Evidence 1944-2003: The Partially Hidden History

This post is inspired in large part by an exchange of emails with Chris Sharpe, an ornithologist who is working on an IBWO literature review. Our correspondence revolved around the IUCN’s species account, which describes the ivorybill as “possibly extinct” and cites recent statistical analyses that suggest extinction is likely, as well as one that […]
