The Bald Eagle has some remarkable abilities, among them being its amazing eyesight over long distances. The Spanish say that a sharp-sighted man has the eyesight of an eagle (vista de águila). Germans have a similar expression (Adlerauge). So for good reason, the eagle’s keen eyesight has been proverbial for centuries.
Interesting is what the Bible book of Job (verses 27-29) has to say about the Bald Eagle, and we can gather several facts about this magnificent bird in those verses; it builds its nest high up (locally there is an eagle nest at the top of a Fir tree, which in turn is toward the top of a butte in the center of town), from lofty perches it searches for food, and its eyes look far into the distance. Here is a modern language quote from Job, chapter 39 and verses 27 through 29:
27 Or is it at your order that an eagle flies upward
And builds its nest high up,
28 Spending the night on a cliff,
Dwelling in its stronghold on a rocky crag?
29 From there it searches for food;
Its eyes look far into the distance.
How far into the distance can an eagle actually see? “Under ideal conditions a golden eagle (Aquila chrysaetos) can detect the slight movements of a rabbit from more than [1 1⁄4 miles] [2 km] away,” explains The Guinness Book of Animal Records. Others have estimated that the eagle can see even farther! What wonders we see in creation!
