A Night Owl. Literally.
They aren't the most famous nocturnal animal for nothing.
Mature Eurasian eagle owls (Bubo bubo) are most active at the moon's two extremes. During full moon nights, this could be because they have to exert more effort to find rodents, which tend to spend more time hidden from view.
Full moons also drive the owls to show off more for potential mates, which as anyone knows is quite exhausting in itself. On full moon nights the owls make more breeding calls, maybe because that's when their sexy white throat feathers can be seen at the greatest distance.
But that doesn't mean the owls get to be slothful for the rest of the lunar cycle. Hunting effort peaks again near new moon, possibly because, even with their sharp owl eyes, the birds have to work harder to spot prey in the dark.
