Why do some birds have red eyes?

In no animal is sight so important as in the case of birds. That is why to increase visual acuity, cones – a type of photoreceptor cells – very often contain red or yellow droplets, which reduce the effects of the so-called chromatic aberration. Generally, the drops in the central area are yellow, and the presence of different colors in neighboring cones also increases the power of discrimination.

For example, the red eyes of the blue kite are great filters of the blue spectrum of the atmosphere, accentuating the contrast of rodents and other prey that make up their diet on the ground.
