The Eagle Diary, Part I

One of my assignments is so much fun.  I have to go sit and watch the nesting eagles. Our law enforcement officer had seen and eagle sitting on eggs March 15 or 16.  The parents start incubating the eggs as soon as the first one is laid. The next egg is laid 48-72 hours later.  So we were expecting babies by about April 27.  But, although the staff usually took a few minutes to look at the nest, no one had seen any babies until I started watching the nest for longer periods of time. I got to bring home their first picture.

Watching them consists of me sitting in a refuge truck, listening to the radio and using my naked eyes, binoculars, and camera.  I use the time on the pictures to catch up with the text report when too many things are happening at once. Then I sometimes can read when I know I'm about an hour away from more action. Here are my notes and SOME of the pictures.  I take 50 - 80 pictures every day, mostly to get the times things are happening and also because I can't yet see the babies with my naked eye and the camera is better than the binoculars.
