This map shows the movement of an Eagle over a twenty year period . It had the tracker fitted in Russia and it finally died twenty years later in the Valley of the Child in Saudi Arabia.It is very interesting… 更多 to see just how far this Eagle travelled over its twenty years of life and the great distances it travelled crossing many countries . Also what is interesting to note is the way in which it avoided crossing the sea .You can clearly see where it took the longest route just to stay flying over land.Many many species of birds spend their whole lives flying over the sea but one thing is for sure and that is that this Eagle certainly avoided crossing the sea.
