Chicken Color Receptors
The Mechanism of Chicken Vision The foundation of a chicken's superior color vision lies in the structure of its eyes. Unlike humans with three cone types, chickens possess four distinct types of cone photoreceptors, making them tetrachromatic and enabling a broader range of colors. Chickens also have a specialized double cone receptor, thought to aid in motion detection.
Discover how chickens perceive colors, including ultraviolet light, and learn about their tetrachromatic vision in this informative article. Estimated receptor responses to the eight stimulus colours used for chicken short (S), medium (M) and long (L) wavelength-sensitive single cones and (D) double cones, relative to a barium sulphate reflectance standard under the same illumination (see also Osorio et al. 1999 c).

The response to the achromatic background was close to 0.3 for the four cone types. Values given are for the highest. Scientists mapped five types of light receptors in the chicken's eye.
They discovered the receptors were laid out in interwoven mosaics that maximized the chicken's ability to see many colors in any given part of the retina, the light. They discovered the receptors were laid out in interwoven mosaics that maximized the chicken's ability to see many colors in any given part of the retina, the light. Are chickens color blind? Nope, in fact, chickens have better vision and eyesight than we do and can see a wider scope of colors as they have more cones to process color.

Cones: Responsible for color vision and distinguishing color Poultry also have distinct visual features different than humans (Lewis and Morris, 2006) (see figure below): Oil droplets: Processes different colors of light Double-cone receptors: Helps in color vision below 400nm (ultraviolet). Chickens have four color receptors, which allows them to see ultraviolet light and certain shades of blue, yellow, and gray. However, they lack a specific receptor that helps us distinguish between red and green.
Researchers have peered deep into the eye of the chicken and found a masterpiece of biological design. Scientists mapped five types of light receptors in the chicken's eye. They discovered the.

Chickens possess a sophisticated visual system that allows them to perceive a rich world of colors, extending beyond what humans can see. Their ability to discern a broader spectrum of light provides them with a distinct advantage in their environment. Unlike human vision, which is considered trichromatic, chicken vision is tetrachromatic, meaning they have four types of color receptors in.
