Hunting Birds with Keen Eyesight  *                                                                                                                   

Hunting birds have keen eyes that enable them to make perfect distance adjustments while they attack their prey. In addition their large eyes contain more vision cells, which means better sight. There are more than one million vision cells in the eye of a hunting bird. Eagles that fly at thousands of meters high have such sharp eyes that they can scan the earth perfectly at that distance. Just as war planes detect their targets from thousands of meters away, so do eagles spot their prey, perceiving the slightest colour shift or the slightest movement on the earth. The eagle’s eye has an angle of vision of three hundred degrees and it can magnify a given image around six to eight times. Eagles can scan an area of 30,000 hectares while flying 4,500 meters above it. They can easily distinguish a rabbit hidden among grasses from an altitude of 1,500 meters. It is evident that this extraordinary eye structure of the eagle is specially designed for this creature. Next : The Thread of the Spider         BACK TO TOP
