By Mel Dyer Yes! Penn Branch has an urban legend. That of the Big Bird or Hawkwoman, who haunts our wild, emerald hills... If you're over 35 and grew up in the Southeast D.C. neighborhood, known as the 'Hollywood Hills' in the mid-1960s, you've probably seen or heard of this creature, at one time in your life. You probably thought you were imagining things ..or that it was just crazy-talk. You may have even heard that it had a woman's head and white, bulging eyes, ..or that it was a witch. While I don't believe that part, I've seen the creature that might have inspired this urban legend, with my own disbelieving eyes, ..perched menacingly on a rooftop, at Carpenter Street and Highwood Drive. It was a turkey vulture ... Right here, in Penn Branch. Why not a hawk? Well, ..I have seen the kinds of hawks we have in this area, up close - like, walking around on a neighbor's lawn - and I don't think they are anywhere ...
