Can buffalo see colors?

Can buffalo see colors?

Buffalo are amazing creatures that have evolved over millions of years to thrive in their environments. Their eyesight and ability to see color is a fascinating topic with some surprising facts. In this article, we’ll explore what science tells us about buffalo vision and color perception.

The Buffalo’s Eye

Buffalo, like all mammals, have two types of photoreceptor cells in their retinas – rods and cones. Rods allow them to see in low light conditions, while cones provide daylight and color vision. Here’s a quick overview of some features of the buffalo eye:

  • Field of vision: 330 degrees
  • Number of rods: About 125 million
  • Number of cones: Around 6 million
  • Ratio of rods to cones: 21:1

Buffalo have excellent peripheral vision from their wide set eyes on the sides of their heads. Their rectangular pupils can open wide to let in light in dark conditions. The high proportion of rods to cones suggests buffalo see best in low light when rods are active.

Buffalo Cones and Color Vision

The cones in buffalo eyes contain photopigments that are sensitive to different wavelengths of light. Based on studies of cattle color vision, buffalo likely have two main types of cones:

  • Blue cones – Sensitive to short wavelengths of blue light.
  • Green cones – React to middle-to-long wavelengths of green, yellow, orange light.

This is similar to color vision in other hoofed mammals like sheep, deer, and antelope. Buffalo lack red cones that are sensitive to long red wavelengths. So unlike humans who see the full color spectrum, buffalo have dichromatic vision.

What Colors can Buffalo See?

With blue and green cones, buffalo can perceive some colors in the blue-green range. But they likely see other colors like red, orange, and yellow as shades of yellowish-green:

Color Human Perception Buffalo Perception
Blue Blue Blue
Green Green Green
Yellow Yellow Yellow-green
Red Red Dark yellow-green
Purple Purple Blue-green

So while buffalo can distinguish blue from green, reds likely appear as shades of green. Purples may look more blue-green. Overall, their world consists of muted, duller colors compared to human sight.

Do Colors Matter to Buffalo?

Though buffalo see a limited color palette, their vision is well-adapted to their needs. The predominance of rods provides excellent night vision to spot predators. Cones allow them to find food and see markings on other buffalo.

But color is not as crucial for buffalo survival as it is for birds who use color to attract mates or animals that use color vision to find ripe fruit. Here are some examples of how buffalo use color vision:

  • Green grass looks green, helping buffalo locate nutritious forage.
  • Buffalo calves have a reddish coat that appears dark green, allowing mothers to identify their young.
  • Though unclear, buffalo may use color among herd members for signaling.

While not as colorful as human sight, buffalo vision gives them the visual information needed to thrive. Their eyes excel at seeing movement and detail, especially in low light. So even with limited color perception, buffalo have an amazing ability to sense and interact with their surroundings.

Comparisons with Other Animals

Buffalo have similar dichromatic color vision to other ungulates like cattle, sheep, antelope, and deer. Dogs and cats are also dichromats, but primates like humans and monkeys have trichromatic vision with red, green, and blue cones.

Other animals have even more types of cones and can see into the ultraviolet range. Here’s how buffalo color perception compares to some other species:

Animal Color Vision Type Color Sensitivity
Humans Trichromatic Red, green, blue
Buffalo Dichromatic Blue, yellow-green
Birds Tetrachromatic Red, green, blue, ultraviolet
Reindeer Dichromatic Blue, yellow-green
Dogs Dichromatic Blue, yellow-green
Goldfish Pentachromatic Red, green, blue, ultraviolet, violet

So buffalo have color vision on par with other hoofed mammals, but more limited compared to many fish, birds, and primates.

How Do Buffalo See at Night?

Buffalo have excellent night vision thanks to a high proportion of rod photoreceptors. In low light, the rods allow them to see in black, white, and shades of gray.

Rods are extremely sensitive and can detect the motion of a single photon of light. This gives buffalo the ability to pick up on subtle movements in dark conditions to spot potential predators. The rectangular pupils of buffalo eyes also open wider at night to allow more light to hit the sensitive rod cells.

In very low light conditions, buffalo rely more on their senses of smell and hearing. But the specialized adaptations in their eyes allow buffalo to see better than humans at night and in dim conditions. Here are some estimates of how buffalo night vision compares:

  • Humans see at 0.0001 – 0.00001 lux
  • Cats see at 0.001 – 0.00001 lux
  • Owls see at 0.0001 – 0.0000001 lux
  • Buffalo see at around 0.001 – 0.000001 lux

So buffalo night vision ranks somewhere between cats and owls, allowing them to navigate and function even in extremely faint starlight.

Adaptations for Low Light Vision

In addition to rods, buffalo have other adaptations that aid vision in dark and murky conditions:

  • Tapetum lucidum – A reflective layer behind the retina that bounces light back through rods for a second pass.
  • Large pupil openings – Allow more light into the eye in low light.
  • High density of rods – More rods concentrated in the center of the retina.
  • Head movements – Scanning motions help detect faint movements in darkness.

Together with the high percentage of rods, these give buffalo the ability to navigate, find food, and spot predators even on the darkest nights. This excellent night vision likely evolved to help buffalo detect threats and stick with the safety of the herd after dark.

Do Buffalo See as Well as Humans?

Overall, buffalo have excellent vision adapted for their needs – but it differs from human eyesight in a few key ways:

  • Buffalo have better night vision, but worse daylight color vision than humans.
  • The buffalo retina lacks a fovea, so their visual acuity is lower.
  • Buffalo have a wide 330 degree field of view compared to 180 degrees in humans.
  • Their rectangular pupils provide great night vision but poorer daytime image sharpness.

So humans see finer details and color during the day. But buffalo eyes excel at detecting motion and work far better than human eyes at night. Neither vision system is universally “better” – they are each adapted to the lifestyles and environments of each species.

Buffalo Eyes and Human Health

The unique structure and genetics of buffalo eyes make them an important model for biomedical research. Studies of buffalo eyes have provided insights that could lead to healthier human vision:

  • Understanding genetic causes of glaucoma in buffalo may reveal new treatments for humans.
  • Learning how buffalo eyes resist cataracts could help prevent cataracts in humans.
  • Studying buffalo photocreceptors gives clues to preventing retinal degeneration in humans.
  • Research on buffalo corneas may improve outcomes of human corneal transplants.

So while buffalo may not see all the colors humans do, studies of their vision system continue to benefit human health!


To summarize, buffalo have dichromatic vision based on blue and green color receptors. This allows them to distinguish some colors like blue and green, but leads reds and purples to appear more greenish-yellow.

Buffalo lack the red cone receptors that give humans our full color spectrum. But they compensate with excellent night vision and motion detection – ideal for spotting danger. While less colorful than human sight, the buffalo’s specialized eyes provide exactly what the species needs to thrive.

Continued studies of buffalo vision and eye genetics promise to uncover new ways to improve eye health in humans as well. So the visual abilities of this iconic animal not only power its own survival, but may lead to healthier human eyesight worldwide.
