What humans do lack is any peripheral vision. If they can change that, life would be interesting. The parrot to the left here < has that problem solved, however, he has other issues.
Interesting notion, but factually somewhat problematic. The issue is in part that ‘
peripheral vision’ means something (subtly) different in eye biology than the way you use it. If you’ll allow me to interpret your comment, I suspect that you’re actually referring to
the size of the entire field of view of both eyes together (expressed in degrees), rather than to
peripheral vision. If you peruse the link above, you can easily imagine that a parrot’s eye has a similar peripheral vision as that of a human (various individual eye differences not taken into account).
One difference between a parrot and a human is the placement of the eyes (to the side or to the front), and the degree of visual overlap of the individual eyes. This difference is also present among
different birds. The parrot's overlap is much less, allowing both eyes to cover a greater field of view, but at the cost of
binocular vision. For that, check out the
raptors, who btw have additional visual goodies up their wings/sleeves.
