Different birds see differently. Pigeons, for example, can see millions of different hues and will shit on your head if provoked. Their vision has nothing to do with the fact that they don’t move out of the way until the very last second.
Horses have amazing, perfect vision except for right in front of them, they have a blind spot right down the middle of their field of vision, giving them binocular vision. Mr Ed was constantly bitching about this terrible inconvenience.
Popular belief held that flies would see thousands of the same image because they have thousands of lenses -this is not true. Flies actually see things very blurry because they are so damn fast.*
