"The bird is a drone that is made in such a way. I only realized it when we were about to get here. That's why I looked for a place that didn't have too many trees so I could know where they were," said Alyosha.
The security system there is very complicated, even what looks like a living being is something different. Something made by humans.
Yes, robots. All the birds observing above the place were robots.
Even though they had not seen any birds up there. But now they saw many birds flying, and watched the land from up there. Some were perched on trees, some landed on the ground, and some were still circling the territory by flying slowly.
Their movements look like birds in general. Even their bodies are completely covered with feathers, with a very exact shape like a real bird. But in fact the birds that fly are fake birds which are robots made by a plural syndicate.
Very impressive.
