Fig. 5. Bark adhesion measurements from the forests along the Choctawhatchee River and comparison sites. Bark adhesion scores for woodpecker feeding trees along the Choctafaula Creek (n = 118 trees; mean score = 1.28 ± 1.48 kg) (A), the Sougahatchee Creek (n = 117 trees; mean score = 1.05 ± 1.33 kg) (B), and the Uphapee Creek (n = 100 trees; mean score = 1.22 ± 1.79 kg) (C) where Ivory-billed Woodpeckers were not detected. (D) Bark adhesion scores for woodpecker feeding sites along the Choctawhatchee River (n = 211 trees; mean score=4.76 ± 6.85 kg) where Ivory-billed Woodpeckers were detected.
