- Moonlight affects red-necked nightjar's hunting: they hunt insects during full moon nights and rely on dusk/dawn when dark.
- Nightjars slow down and lower body temperature to conserve energy on dark nights, a rare hibernation-like strategy in birds.
- Full moon triggers increased food intake and energy buildup, enabling preparation for migration, which starts about two weeks after full moon.
- Moon's rhythm influences breeding: eggs are timed for chicks to hatch when nocturnal insect supply peaks for survival.
- Nocturnal animals are vulnerable to light changes; light pollution and climate change can disrupt life cycles and energy balance.
