Don Eckelberry's Ivory-bill description

Don Eckelberry saw the last documented American Ivory-bill in 1944. At this link, I found his description of one encounter with this bird:
---
"She came trumpeting in to the roost, her big wings cleaving the air in strong, direct flight, and she alighted with one magnificent upward swoop. Looking about wildly with her hysterical pale eyes, tossing her head from side to side, her black crest erect to the point of leaning forward, she hitched up the tree at a gallop, trumpeting all the way. Near the top she became suddenly quiet and began preening herself. With a few disordered feathers properly and vigorously rearranged, she gave her distinctive double rap, the second blow following so closely on the first that it was almost like an echo--an astonishingly loud, hollow, drumlike Bam-am! Then she hitched down the tree and sidled around to the roost hole, looked in, looked around, hitched down beneath the entrance, double-rapped, and went in.
"At 7:20, after I had finished all my notes and we were about to leave, she popped out and raced up the trunk to its broken top where, bathed in rich orange light of the setting sun, she alternately preened and jerked her head about in a peculiar, angular way, quite unlike the motions of any other woodpecker I knew. I was tremendously impressed by the majestic and wild personality of this bird, its vigor, its almost frantic aliveness."

If the Ivory-bill still lives, I think we would likely have recent, clear video documentation of similar encounters.
