How Does Celestial Cues Work?

Celestial cues are like invisible messages from the sun and moon that help animals know when to sleep, eat, or do fun things.

Imagine you're playing with your favorite toy every day at the same time, that’s how some animals feel. When the sun rises, it's like a big, bright clock in the sky saying, “Time to wake up and play!” And when the moon comes out, it’s like a soft nightlight telling them, “It’s time to rest.”

Some animals use these cues even if they can’t see them. Like how you might know it's bedtime because your parents turn off the lights, even if it's still bright outside.

• Some birds fly long distances using the sun as a guide, just like how you use a map to find your way.
• Nocturnal animals, like owls, start hunting when the moon shines, helping them see better in the dark, like having a flashlight on during a midnight snack.

These cues are like nature's own alarm clock and nightlight combo, simple but super smart!
