What is this movements purpose?
The Birds Aren't Real movement exists to spread awareness that the U.S. Government genocided over 12 Billion birds from 1959-2001, and replaced these birds with surveillance drone replicas, which still watch us every day. Once a preventative cause, our initial goal was to stop the forced extinction of real birds. Unfortunately this was unsuccessful, and the government has since replaced every living bird with robotic replicas. Now our movement's prerogative is to make everyone aware of this fact.
What do you mean Birds Arent Real?
The term Birds Arent Real refers to biological Birds no longer existing on United States soil. After the government forcibly made the entire species extinct in the 20th century, all of these real birds were replaced with surveillance drones designed to look just like Birds. To simplify- Birds no longer exist in the U.S. as a biological lifeform, thus, Birds Arent Real!
What are eggs?
The eggs we see in the 21st century are specifically designed by the government to appear indistinguishable from what eggs once were, when birds were real. When the government replaced the species with robotic replicas, it was key that these replicas sustained the same activities that their biological predecessors did, including producing edible eggs.
What is bird poop?
Bird poop was originally thought to be oil discharge from earlier bird drone models. After further research though, this was disproven. Bird poop irregularly falls on vehicles in large amounts. Recent studies show that 87% of Bird Poop in populated areas falls on peoples cars. Why is this? Confidential documents leaked in 2018 revealing that Bird Poop is actually a form of liquidated tracking apparatus. If you walk outside and notice some bird poop just happened to fall on your car, be aware that you are now being tracked by the United States Government. It is recommended you clean your car exterior regularly to avoid this.
I love the bird poop explanation!
