One can readily see from the results that life expectancy increases if the juveniles make it to adulthood. There is much to learn socially, geographically, prey species wise in the art and craft of becoming a good hunter and fisher and comptetitor on winter range; This is as I expected.
I used curvefit programs to fit the life survivorship tables my surveys generated and created a smoothed life table projecting the eagle life expectancy until it hit the x axis. This what I got.
I consider this a fabulous piece of work and had a toast with a glass of wine when it came together. I am grateful to my now deceased wife without whose patience none of this would have been possible.
