The outage was reported about 9:30 a.m., and is believed to have been caused by sticks from an osprey nest falling into the power equipment and shorting out the line.
As many as 76 customers in the Jamestown area lost power, according to the San Francisco-based utility.
All but two customers had their power restored by 5 p.m., said PG&E spokeswoman Lynsey Paulo.
The nest will likely be removed.
“When they got there, the nest was inactive and empty,” Paulo said of the utility crew that responded.
Had the nest been occupied, it would have been a bigger issue.
Before it was determined to be empty, PG&E called Nina Resnick, of Rose Wolf Wildlife Rescue and Rehabilitation in Sonora, to aid in relocating the nest.
Resnick, whose organization regularly conducts bird and other wildlife rescues, said California Department of Fish and Wildlife had informed her the nest could not be moved because the bird of prey is listed as a species of “special concern.”
“It was kind of exciting to know that there were no babies in there,” Resnick said.
Native to much of North America, osprey commonly build their large stick nests atop manmade structures, such as telephone poles.
