Singer Tract Area Ivorybills in 1948

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 […]

Bark: An Exegesis

Introduction: According to Tanner, scaling bark was the Ivory-billed Woodpecker’s primary foraging strategy during breeding season in Louisiana. Tanner wrote that the ivorybill is “capable of easily scaling away heavy bark that other woodpeckers could not loosen.” (Tanner 1942). All woodpeckers in genus Campephilus have specific anatomical characteristics that enable them to forage in this […]

Trip Report December 16-21, 2016, Part 1

On this trip, I was joined by Patricia Johnson (my wife) who was making her first visit to our search area in over two years. Phil Vanbergen was along on Friday, when a classmate of his, Jeremy Irion, spent also spent the day with us. Steve Pagans, retired forester at D’Arbonne National Wildlife Refuge, was […]

Trip Report: October 13-18, 2016

This was an eventful trip, with an extraordinary amount of activity on the first four days – including a possible sighting and several possible auditory encounters – and none at all on the last two. I was alone on October 13th, 17th, and 18th; Frank joined me from the 14th-16th. Conditions were generally good – […]

Insights, Ants, and Old Growth: a Nuanced View of the Ivorybill’s Decline and Possible Survival

I’ve just finished reading Tanner’s dissertation and have gained some new insights into topics that have been discussed in a number of earlier posts. Conventional wisdom, following Tanner, holds that the Ivory-billed Woodpecker’s decline and possible extinction were caused by habitat loss, specifically the logging of old growth forests during the 19th and early 20th […]

Two More Rare Ivory-billed Woodpecker Images

These two photographs, taken by Tanner in 1938 and published in his dissertation, have not been otherwise widely disseminated or (to the best of my knowledge) reprinted elsewhere. Each is interesting in its own right, and not just because they add to the small body of indisputable ivorybill imagery; the first shows the behavior of […]
