In search of a perch, the Harrier Hawk lands on a power pole. Suddenly, electricity crackles. The raptor combusts. Its burnt body falls to the ground. The surrounding grass erupts into flames.
This has gained attention in the scientific community, with steps being taken to reduce these chances.
This past summer alone, Colorado experienced three brush fires due to bird electrocutions. It’s occurred in other states as well.
FRCC instructor James Dwyer, who works for electrical utility consulting company EDM International, said more utilities are undergoing more inspections to determine electrocution susceptibility. Inspectors look for where birds could touch two live parts to complete a circuit or touch grounded parts of a pole. With drones, Dwyer said, this has become more accurate and efficient.
When electrocution-prone areas of electrical lines are identified, he said, there are three modifications that can be implemented: separation, redirection, and insulation.
Separation replaces cross bars that support power lines. This adds space between lines so birds can’t touch two at once. Redirection uses perch deterrents, that challenge the bird’s ability to sit or nest on poles. Due to less cost and efficiency, Dwyer said, insulation and covering of “energized parts” is the most common method.
When asked about the potential use of AI in electrical utility inspections, Dwyer said this could aid in the efficiency of inspections in the future.
