I am not sure what kind of bird it is, but found it surprising it was just sitting back there. It looks like a juvenile and it’s hard to determine what color feathers it’s finally going to have. It seemed a bit lost and skittish, but not enough to fly or run away when I approached it.
After consulting with my Peterson's field guide to eastern birds, it may be a Limpkin or Ibis.
