Oscar first introduced himself to me on a beautiful sunny day in the early and snowy winter. I was struck by how close he came to me, and how he seemed small and conspicuously alone.   In retrospect, at the time, it felt a bit like looking in a mirror-perfect reflection of a calm lake. A friend later told me that he likely had been abandoned by his flock, since Canadian Geese are usually social animals.  I didn’t know if that was true, but the possibility wrenched my heart.
