what it doesn't tell you is how to determine the blind spot in front of your nose or off to the sides.

Depth perception is important to humans. If hunting means pouncing on something at close quarters, it isn't quite as important.
Unless you are the king of the jungle and nothing is gonna mess with you, you had better move about in groups if you can't watch your own back.
I wonder about the differences between songbirds and birds of prey.

song birds are still 'birds of prey', they just prey on insects instead of hunting for small animals.

Wait. Insects are small animals.
Still, there must be differences between the eyesight of a finch and, a falcon cruising at 30mph through the forest trees.
Or, a sparrow cleaning aphids off sunflower leaves and a hawk hovering 200 feet above a yellow perch, swimming too close to the surface of the river.
