Confirming a killdeer

  • Two black bands across the white chest. No other plover has two.
  • Bright orange rump and long tail, obvious in flight.
  • Runs, stops, bobs, runs again.
  • Feigns a broken wing, dragging it along the ground to lead you away from the nest.

Confirming a spotted sandpiper

  • Constant teetering of the rear body, all the time.
  • Flies low over water on stiff, shallow, fluttering wingbeats.
  • A white wedge cutting up in front of the folded wing.
  • Round black spots below in summer; plain white in winter.
