In late December 2014, I wrote what I’ve described as a speculative post titled, “Is There a Way to Recognize Ivory-billed Woodpecker Excavation? In that post, I relied on Tanner’s Plate 11, a brief description from the monograph: “When Ivory-bills dig, they chisel into the sap and heartwood for borers like other woodpeckers, digging slightly […]
Part 1 is here. The second observation from the Singer Tract I want to discuss took place in May 1932, when Audubon Society President, T. Gilbert Pearson and Audubon Sanctuary Director Ernest G. Holt were the first ornithologists to observe Ivory-billed Woodpeckers (a minimum of three separate individuals) on the Singer Tract. As discussed in […]
I flew into Houston on February 4 and arrived at the search area on the morning of the 5th. Frank’s work schedule had precluded him from returning to the search area during my absence, and he was unable to get time off to join me this trip. Tommy Michot visited on the February 5th; we […]
Careful examination of bark chips found in conjunction with extensive scaling is one of the key elements in our diagnostic gestalt, but “chips”, a term I’ve been using for years, is both inaccurate and too vague for what we believe is being left behind by Ivory-billed Woodpeckers and for differentiating it from the leavings of […]
The first two installments in this series, which was inspired by the discovery that squirrels are doing some of the bark scaling in our search area, are here and here. This installment will consider the appearance of the scaling itself, and the next will focus on pieces of bark; “chips” no longer feels sufficient to describe […]
Part 1 of this series is here, and the event that led to my writing it is discussed here. I now expect to write 2-3 additional posts on this topic and may create a new page that summarizes the whole series. I’ve hidden the Bark Scaling Gallery page to be reworked later or incorporated into […]
This is will be the first in a series of 3-4 posts. The subject is multifaceted and subtle. Nuances can be hard to convey in words and accompanying illustrations; it’s easier to do in talks, with bark chips in hand to provide a more visceral sense of what’s being described. Still, it seems important to […]
Part 1 is here. Thursday the 26th was Thanksgiving, and Frank spent the morning cooking. I ventured out alone; I get less comfortable going solo every year. Because I’m not very good with a GPS, I tend to prefer visiting areas I know well or restricting myself to places where I can rely on my […]
This post will be something of a departure from previous ones in that we’re writing it jointly. Though we met in 2008 and started calling our effort “Project Coyote” in early 2010, in many ways this week marks the 6th anniversary of our collaboration. It was the first time we visited the old search area […]
I’m looking forward to returning to Louisiana at the end of the month and have high hopes that our trail cams will reveal just what’s removing bark from the trees in our search area. In the meantime, I thought I’d compile a new group of links to images showing bark scaling (without accompanying excavation) done […]
