As of October 2019, Project Principalis has a new home and a new partnership with the National Aviary. Visit the new blog for updates and new information. You can also make a tax-deductible contribution to the Aviary to support the search, just click the large blue button below the descriptive material.

As of November 2021, this blog is featured in two books, one recently published and one forthcoming.

Guy Luneau’s, The Ivory-billed Woodpecker: Taunting Extinction: Survival in the Modern Era includes his elegant analysis of one of the images from 2009.

Title notwithstanding, I think J. Christopher Haney’s Woody’s Last Laugh: How the Extinct Ivory-billed Woodpecker Fools Us into Making 53 Thinking Errors is the most important book on the ivorybill since Tanner, at least; it’s an absolute must for anyone regardless of where they stand on the controversy. It’s an honor to have been so frequently referenced.

I will be restoring selected older posts, mostly pertaining to the IBWO’s natural history and my hypotheses about foraging sign, habitat, and behavior. My thinking on many of these matters continues to evolve, and I want to share as much of the process as possible, including some of the blind alleys I’ve followed. Material posted here does not always reflect the current state of my understanding.

Field efforts are ongoing and there have been a number of updates to the Aviary site. There should be more of them going forward.
