The concept is very good, I really liked it, something that surprised me is the movement of the birds, it looks very real, how did you achieve it?

Thanks! The bird physics were inspired by how real birds flock. I have one (invisible) lead bird who always tries to navigate in the direction of the player (with weighted randomness added to the up/down movement, to simulate swooping down). Every other bird tries to navigate to the place the previous bird was one frame ago.
The key part is that they don't immediately change their direction, only their speed. So every time they get close to their target they overshoot and have to correct the course again.
