Multi-generational Whitetailed Doe Home Range

Recently, I queried a question to my blog readers to see if they may have seen a behavior that I have observed here . That of the returning year after year of a whitetailed doe to the same place to birth and raise her fawns. It took a little phrase manipulation in my GOOGLE searches to find exactly what I needed. Using the phrase "Whitetailed Doe Matriarchal Home Range" brought me to the pages that seemed to read my mind and provide the answers I sought. One site in particular that I came across gave a twenty year time-line. Researchers Michael E. Nelson and L. David Mech of the Biological Resources Division, U.S. Geological Survey, Northern Prairie Wildlife Research Center, 8711 - 37th St. SE, Jamestown, ND 58401-7317, U.S.A., provided in-depth generational dispersions.

If you happen to be interested in knowing the home-range tendencies of the whitetail doe, clicking on the whitetailed doe link will open up the documented findings of Researchers Michael E. Nelson and L. David Mech at the United States Geological Survey website. I found at that point going down to the links in the lower left corner right under the discussion article would get you back to the research. Another link I tried to provide has not been recently updated so it isn't available to get you directly to each segement. In my opinion to use a coined phrase "The apple doesn't fall far from the tree" would absolutely fit the behaviors of the does. They may move a little further out with each generation. However, matriarchal bloodlines are still found within a defined area. As I reflect on the information it supports my own observations. Certainly I won't be going out and putting tracking collars on the does, or getting blood samples to verify relationships but I could get some pictures from year to year. The question has been adequately answered in my estimation and will go on from now into eternity...;)
