ANS:
Will vary, but should include: trade-offs between total field of vision and range of binocular vision. The eyes of an owl are positioned in front of the head, allowing binocular vision across most of the field, which is lim-ited to about 180 degrees. The eyes of the ostrich are set on opposite sides of the head, yielding nearly a 360-degree view but with only a small range of binocular vision. Binocular vision is better for hunting; pe-ripheral vision for avoiding predators.
