Eastern side of North America from northest Newfoundland to southest Florida, western Texas and Midwestern United States, and north to central Alberta. West of the Rockies, it is replaced by the closely related Steller's Jay. Blue Jay is slowly spreading westward.

Although this bird is generally found year-round through most of its range, some northern birds do move into the southern parts of the range. These birds migrate in the daytime.

  • Harsh cries, and a rich variety of other calls.
  • One is almost identical to the scream of the Red-shouldered Hawk.
  • queedle-queedle often referred to as the "rusty pump" owing to its squeaky resemblance to the sound of an old hand-operated water pump.
