A fish falling from the sky has sparked a wildfire and power outage in rural Canada.

Firefighters believe the blaze was started after an osprey got tired in the heat and dropped its prey onto power lines, causing a short circuit.

The unusual event occurred on July 30, about four miles south of the town of Ashcroft in British Columbia.

Firefighters shared photos of the charred fish on the blackened ground on social media.

They said investigators found that the fish 'had been dropped by a local osprey onto hydro lines,' with the resulting embers starting the fire on the dry grass below.
