Well, to tell you the truth, I don't know where it comes from, but I LOVE watching eagles in flight, they are so beautiful, and sometimes I even envy them thinking why people don't fly...
In order to better see them, you need to get a good clarity with the help of your
birding binoculars. You'll need to go for at least 7x35 magnification, and you also need to be prepared to spend a good portion of money for the good pair of
binoculars. That'll be only one part in order to reach your goal.
When you go to watch eagles or any other birds never wear white or bright colors, because it drives the birds off.
When you are in the process of looking for birds with your
binocular, rise it to your eyes without moving your head.
When the trees leaf out, the only way to locate birds sometimes would be by their sounds.
So, there many tricks that you'll acquire when you start observing birds. This is one of the best hobbies that helps you relax and unites you with nature.
Good luck on your watch!
