Coexistence - Round 2

I just can't seem to remember the new killdeer nest and so am startled every time I walk by and the birds freak out.  Once my heart palpitations quiet enough so I can hear it, the little voice of guilt starts whispering because I've disturbed the little beasts once again.  But then I realize that they endured us once, maximized their fitness by hatching all 4 eggs, and came back for more; so, I guess we aren't such bad neighbors after all.  At least we don't eat them or any of their 4 dear eggs.  Marian and Katrina are the gracious hosts this time - who will be next???
