Wrong. The guy who started it has been interviewed at length. He started it to openly mock the nutcase conspiracy theorists and would show up at whatever tinfoil hat wearing protests were going on with his signage claiming birds are all government drones. He has an amazing website that never lets in on the joke, including an FAQ with answers to questions like “What about birds that people hunt and/or roadkill? How do you explain bird guts?”
The guy is a hoot.
