Possible encounter while volunteering at Macbride Raptor Project outside North Liberty

Two volunteers were feeding birds at a raptor center late at night when they heard something large moving in the woods beyond the cages. They followed sounds of heavy footsteps and snapping twigs along a walkway for about 30 minutes as it moved toward a reservoir inlet. Both reported seeing large red eyes during the pursuit but did not describe seeing a body.

Rock clacking heard near Cardinal Marsh south of Cresco

The witness hiked into dense timber to scout for signs and found arches, tree breaks, and woven saplings. After hearing an unexplained sharp noise from the hilltop, the witness waited and then heard two distinct clacks described as rocks struck together. The witness then left the hill and exited the area.

Memory of a possible encounter as young girls riding horses at night near the Coralville Reservoir

Four girls were riding horses on a moonlit night when their horses stopped and focused on a hilltop ahead. They heard a loud guttural growl mixed with vowel-like sounds and wood snapping, which frightened them. They galloped back to the farm where they were staying. The next morning they found a small wooden corral they had built on that hilltop broken apart.
