About 42 acres of wildland burned and cut off power to nearby windmills Friday afternoon at Jump Off Joe south of Kennewick, Benton Fire District 1 reported.
Capt. Devin Helland said the accumulation of waste left by ravens nesting in power lines arced the wires, sending sparks below to start the blaze.
The fire started about 12:25 p.m. and was contained in about an hour, he said.
“If birds can start fires this easily, think of what people can do,” he said.
