Nocturnal migratory #birds follow rhythm of the moon https://phys.org/news/2026-05-nocturnal-migratory-birds-rhythm-moon.html Moonlight drives the energy balance and annual cycle of a nocturnal forager https://www.science.org/doi/10.1126/sciadv.aed8204 "Moonlight determines when the red-necked #nightjar feeds, migrates and raises its young... the bird's entire annual cycle follows the moon's rhythm... when the moon is full, the bird can hunt insects for much of the night. When it is dark, it is instead forced to rely on brief hunting opportunities at dusk and dawn."
