Photographer fits tiny camera to ‘hummingbird’ to secretly enter monarch butterfly’s kingdom

The hummingbird drone looks a lot less threatening than the modern ones that look like alien invaders, and it is safer with its screened, rotating blades.

Scientists use a drone shaped like a hummingbird to safely spy on Monarch butterflies in a Mexican forest. Its blades are covered with a screen.

The drone flies close to the trees. The butterflies are clustered together for warmth on the branches and trunks to protect themselves from the cold.

When the sun warms the temperature above fifty degrees, the butterflies’ wings dry, and they prepare to fly. The drone’s buzzing does not threaten them.

The movement changes from a slow flutter to a fast swarming wave. The butterfly wings the flight of a flock of birds filling the sky.

Looking for flowers, the butterflies will spread out, searching for nectar. They return to the same forest every year as they migrate from Northern territories.
