Confirming a red-winged blackbird

  • Male: black with red-and-yellow shoulders, though the red can be hidden when not displaying.
  • Female: heavily streaked dark brown, with a pale eyebrow and a long pointed bill.
  • Sings from the top of a cattail or a fence post with wings spread and tail fanned.
  • Almost always near water or wet ground in the breeding season.

Confirming a common grackle

  • A pale yellow eye — obvious even at distance.
  • A long tail held in a V-shaped keel in flight.
  • Iridescence that changes from bronze to purple with the angle of the light.
  • Walks on lawns in loose flocks.
