Which evidence best supports that a nocturnal habit helps survival: fewer daytime predators or brighter feathers?
Which evidence best supports that a nocturnal habit helps survival: fewer daytime predators or brighter feathers?
Tap to reveal answer
Fewer daytime predators (and less competition for food). Most predators hunt during day, so night activity is safer.
