2/3 Using high-resolution sensors, we followed male barn owls across 354 nights and >17,600 hunting attacks.
White morphs actively used bright moonlight: they faced the Moon in high illuminated nights, hunted in more exposed/illuminated places, and concentrated activity during brighter periods.
3/3 Reddish morphs were more likely to stay in the shade.
White owls did not strike more accurately, but in bright moonlight they caught more mice and voles in less time. Their conspicuous plumage may turn moonlight into an advantage by briefly freezing prey.
