Did you know:
1.Spaniards describe a sharp sighted man as having the eyesight of an eagle (vista de aguila). Germans have a similar expression (Adlerauge).
2. Under ideal conditions a golden eagle can detect the slight movements of a rabbit from more than 2km 1 1/4 miles away.
3. The golden eagle has two huge eyes which occupy a large portion of the head. It's eyes are infact as large as they could be without becoming so heavy as to impair flight.
4. An eagle eye has approximately five times the number of light receptor cells that we have-some 1,000,000 cones per square millimeter compared to our 200,000.
5. The eagle's vision excels during broad daylight but at night the owls have the advantage.
