What does it mean when wildlife biologists say that “an eagle can see a rabbit in a field from miles away”? Does this imply that their vision is automatically more zoomed in? Do they have better than 20/20 vision, or is their vision simply clearer?

What does it mean when wildlife biologists say that “an eagle can see a rabbit in a field from miles away”? Does this imply that their vision is automatically more zoomed in? Do they have better than 20/20 vision, or is their vision simply clearer?

Another element of this is the literal neural network their eyes are attached to. The ability to “see” a rabbit in a field a mile away is as much the impressive data captured by their eyes as it is the neurons interpreting that data into “there’s a rabbit in that field”. Consider that a human could be staring at a rabbit several feet away and fail to “see” it.
