| Question about Pets:Whether all the birds including CROW have binocular VISION? |
"Depth is perceived when each eye provides a slightly different view of the same scene, when there is an overlap in the field of vision. This is known as binocular vision. Birds such as Owls, which have both eyes facing forward, have binocular vision similar to our own, but most nonpredatory birds have eyes whose fields of view do not overlap enough to provide this ability. Instead, their laterally placed eyes give them a wider total view, the better to detect an approaching predator. Scientist believe that to compensate for their lack of binocular vision, some birds bob their heads, thereby viewing the same subject rapidly from different angles. Dippers bob nonstop along mountain streams. Many shorebirds bob rapidly when a predator appears nearby."

So, no, not all birds have binocular vision. Only birds with both eyes in the front of their heads have binocular vision, so crows, which have laterally placed eyes (one eye on each side of the head), do not.
