Video prompt: A pelican swoops low over the bay, skimming the waves before stitching upward to dive-bomb its quarry.
Defect: Deformation (any reason involved with a movement)
Explanation: This bird over the sea should be flapping its wings as it flies, rather than remaining unnaturally still in midair. Its lack of motion defies the expected behavior of a bird in flight, making its presence appear unrealistic and inconsistent with natural dynamics.
