  • A lone Great Blue Heron (Ardea herodias) stood motionless on the edge of a nearly dried pond, patiently scanning for prey — a reminder that waterfowl sometimes adapts to less-than-ideal conditions with remarkable poise.
  • A persistent beaver (Castor canadensis) resurfaced through the ice, reminding observers that these industrious mammals maintain open water access even as winter tightens its grip.
  • Another heron (Ardea herodias) was seen at a second body of water, illustrating local movements among low ponds as birds searching for sustenance.
  • The staccato drilling of a woodpecker came from nearby trees, suggesting insects still hide beneath bark even in colder months — and that woodpeckers are still on the hunt.
