Eagle on an Osprey Nest

One morning last week we found this eagle sitting on the osprey nest with a fish.  She was not eating it but was very concerned that it not be taken from her.  She constantly looked around.  After about an half-hour she left (with the fish).  The story unfolds in the following photos.  These are extremely cropped, hence the lack of sharpness.  I did use a tripod and an effective 420 mm lens (300 X1.4).  Thanks for looking.
