A schematic representation of an owl hunting a rodent at night, illustrating the interplay of radiometric quantities affecting camouflage. The owl's white underparts reflect light, while the diagram shows arrows representing light from the moonlit sky, ground reflectance, and other radiometric factors, demonstrating how the owl blends into the background. The rodent, depicted below the owl, observes the scene. Various mathematical symbols label radiometric quantities, including sky radiance, ground reflectance, and light interactions.

Beneath the Hunter’s Gaze

Barn owls’ white plumage camouflages them against moonlit skies, enabling stealthy hunting by blending into their background and avoiding detection.
