In the Bicentennial celebration of 1976, I attended the Boston parade dressed as a bald eagle, a very patriotic toddler indeed. I was told at the time that the bald eagle I was impersonating had gone extinct. I didn’t bother to update this knowledge until several decades later, when I was gobsmacked to stumble across one that was very much alive. It was like seeing a dodo or a woolly mammoth perched in the branches. In my eyes the bald eagle is still the picture of resilience, a creature capable of defying extinction itself, a phoenix among beasts.
