What is the differences between crows with black eyes and crows with blue eyes?

Crows with black eyes are typically the common American crow, while those with blue eyes may be a result of genetic mutations or specific variations, such as the leucistic crow, which has reduced pigmentation. The eye color can affect their appearance, but it does not significantly influence their behavior or intelligence, as both types are highly adaptable and social birds. Environmental factors and lighting can also affect the perception of eye color. Overall, the differences are mainly aesthetic rather than functional.
