As most weather patterns push from the Northwest down and across the country toward our region, these birds ride the fronts until the fronts dissipate approaching the coast. The same currents push hawks toward the coastlines, as well. While these currents could conceivably push an Allen's out of the west, that is not as likely due to the north to south movement of these currents. The long migration of the Rufous has dropped it into every state in the union at some point, Hawaii excepted. Next, although less reliable than the field marks below, the size of this particular bird indicates a Rufous.
Size can be tricky for birders, beginning or otherwise.
When the difference in size is only a half an inch as it is in this instance, that difference might be easily overlooked. Now to the real identifying traits. The rufous wash on the lower back is fairly evident. This makes the bird distinct from an Allen's, as do the rufous colored flanks. The lack of the jewel means this is a female bird.
