Answer 2

Answer:

Birds move their neck very often to see any threat or danger or any hunter is attacking it. Also, some birds can't move their eyes enough to look around so they move their head to see around.

What the head bobbing lets pigeons do is momentarily fixate their eyes on objects. This gives the photoreceptors in their eyes enough time—about 20 milliseconds—to build a steady scene of the sidewalk world. And this has nothing to do with their bird-size brains. Vision doesn't mix well with movement.
