Owls, like most birds or prey, have excellent vision. Seeing as how owls are nocturnal, they have particularly good night vision, estimated to be up to 100 times more powerful than a human’s.
But with this amazing eyesight, can they also see in color?
The answer is that owls are indeed color blind, as are most other nocturnal birds. This means that owls can only see black, white, and shades of gray.
When you really think about it, it does make sense. Being the case that owls only hunt at night, there wouldn’t be much use for color vision. Why take up space in the eye for color detectors, when more light detection would be far more useful?
How do they scientifically determine that they are colour blind?
Possibly by examining the number of Rods and Cones, which are the receptors for color, in the eyes of them, though I dont know for sure
