Answer 1

Not all birds do! And there’s a common trait among the ones that do. The ones that do all have their eyes on the side of their head (as opposed to the front of their head). This is a trait of non-predatory animals in general. It’s beneficial because it allows for a greater range of vision. But the cost is depth perception. But by bobbing their head they can see from two points and get a little idea of the distance of the things they’re seeing.
