Good for You, Birds!
A bird sees everything at once in total focus. Whereas the human eye is globular and must adjust to varying distances, the bird’s eye is flat and can take in everything at once in a single glance.

Once did an article on blue herons - not only that but the blue heron can focus each one of its eyes separately and can adjust its focus to clearly see what is moving under water. Doesn't help when one takes off with your fish but interesting all the same.
That makes the happenings in Hitchcock's "The Birds" even scarier Joy.
