In this incredible Nature by PBS video, a drone disguised as a hummingbird captures a breathtaking Monarch Butterfly swarm. Since butterflies and hummingbirds often feed on the same plant nectars, the monarchs are not afraid of the hummingbird drone and, in fact, do not react to the drone at all! The video was shot in Mexico and starts in the cool early morning hours. As the temperature increases, the butterflies become active and take flight, some even landing on the wings of the hummingbird drone. The drone was designed so that all of its moving parts are shielded, therefore protecting the Monarchs. What a wonderful opportunity to witness this awesome Monarch Butterfly display!
