A single bird, not in a flock
Photo does not show the bird, just the trunk of the tree were it had been foraging. Three Bioblitzers who are also all birders were standing very near this tree when one pointed out a Brown Creeper on its trunk at about eye level. The others confirmed the ID. We didn't get the photo taken until after the bird flew off. Seen during the Heart of the Island Bioblitz 2022.
