The researchers became increasingly uncomfortable as the behavior continued.
They tried making noises to determine whether the birds were reacting to a sound outside the range of human hearing. They tested for nearby disturbances and examined the surrounding environment for anything that might explain the unusual gathering.
Nothing produced a satisfactory answer.
Then reports began arriving from other locations.
At a zoo thousands of kilometers away, several birds of prey had begun exhibiting almost identical behavior. Golden eagles, hawks, and owls repeatedly turned their attention toward the same empty section of the sky.
The species were different.
The locations were different.
The environments were different.
Yet their behavior was remarkably similar.
They were all watching something.
Something that human eyes could not perceive.
The internet reacted almost immediately.
