How much better can a bird see than human?

The visual acuity of birds is typically much better than that of humans. Birds have a higher density of photoreceptor cells in their retinas, which allows them to see finer details. Additionally, birds have a wider field of vision than humans, allowing them to see more of their surroundings at once. Some birds, such as raptors, have specialized adaptations that give them even better vision than other birds.
