Cambria had a 20-minute power outage on Sunday that started about 7:25 a.m.
The blackout threatened to snarl Sunday plans and downtown commerce on what had been an exceptionally busy summer weekend.
About 4,100 Pacific Gas and Electric Co. customers were affected, according to Kory Raftery, a spokesman for the utility.
While utility crews got the power back on quickly by rerouting the circuits, they're still unsure what caused the outage.
However, Raftery said, "We got reports that a turkey flew into the equipment" on Santa Rosa Creek Road, near Coast Union High School.
Cambria has large populations of both wild turkeys and turkey vultures.
