This is my 100th post on the blog. On the weekend of March 4-5, Phil Vanbergen visited the search area and changed out the card on our deployed trail cam. He found that Pileateds had hit the target tree, scaling a single and large strip of bark during one of several visits. The raw sequence […]
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 […]
Part 1 is here. Part 2 is here. I encourage you to read those posts first, as this one only adds a little to what’s been documented and discussed. Phil Vanbergen found an additional sequence this morning, one that shows the balance of the scaling that was done on the limb between December 22nd and […]
Thanks again to all who sent condolences, and appreciations of Frank Wiley and our work. Your sympathy and support have comforted and encouraged me during this difficult time. Part 1 is here. This post supplements the analysis at: Feeding Sign: Some Possible Ivorybill Diagnostics. I’ll be reiterating ideas that are familiar to longtime readers; I have posted […]
I’m still in mourning and adjusting to the loss of my friend. Thanks to all who have expressed appreciation for our work and a desire for it to continue. I’m sure Frank would have felt the same, and with that in mind, this will be the first of two or three installments discussing Pileated Woodpecker […]
Part 1 of this report is here. Patricia opted to take the day off on the 19th, so I went out on my own and covered a lot of territory. I had been thinking hard about the hickories and the fact that, in virtually all cases, we’ve seen indications that bark is removed from these […]
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 […]
I’ve created a page that expands on this post and should provide a good introduction to our thinking about the three most intriguing types of feeding sign, with images from the second and third categories. Think of this post as the shorter version. Over the years, I have written a great deal about bark scaling […]
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 – […]
1967 slides taken by Neal Wright of a putative Ivory-billed Woodpecker in Texas are viewable on Vireo (search Ivory-billed Woodpecker), but high resolution scans have not been widely circulated as far as I know. These images were not made public until after the the Arkansas “rediscovery”, more than three decades after they were obtained. Wright’s story […]
