It’s real.
Don’t be fooled by those passive little birds, flying around and eating berries and seeds. They are kin to the dinosaurs, and not the cute ones with the long necks or three horns. Inside the heads of these birds is a tiny mind with big ideas. Ideas big enough to choke all humanity.
And when people are gone, the winged-ones can assume their proper hierarchical role at the top. Just like the good ol’ days.
Caww ha ha ha!
