In a grove in the mountains of Mexico, a half a billion monarch butterflies sleep clinging to the trees.
Having actually traveled from regarding Canada to leave the cold winter season, they return to this exact spot. How they’re able to do that, no one understands for sure. This rare spectacle is caught on video camera with the help of a spy “hummingbird.”.
They huddle with each other while resting to save warmth and wait for the sunlight to warm up their wings. And then it’s time to fly. What begins as a trickle quickly comes to be a swarm of beautiful butterflies covering the sky! It’s a breathtaking sight to behold.
