How does the chicken see?

The chicken (Gallus gallus) is a bird in the order Galliformes. Its eyes belong to the vision type Panoramic grain-eater and wader: 4 cones (violet-sensitive), low-moderate acuity, ~300-360 deg field, small binocular zone.

Measured in this species: colour, sharpness, foveas, night vision and motion (flicker fusion). Measured core: measured values on at least 3 of the 6 dials. Every value below carries its evidence level and sources; nothing is typed by hand.

The six dials

Evidence levels: how the tiers work. "Measured" means a value measured in this species; "Estimated" values come from a close relative or an eye-size formula.
