As a leading electrical infrastructure inspection company, it’s critical that we understand the various issues that can arise for electric cooperatives across America. In some recent inspections, we have seen an increase in wood pole damage – leaving significant holes across cooperative infrastructure.
Who or what is causing all of this damage? Coming in an array of colors, shapes and sizes, and quickly taking flight before they can be caught, it’s the North American family of birds.

Now a quick word about the bird (rhyming intentional). We here at Clearsight have a particular fondness for our feathered friends and do what we can to protect their natural habitats. Birds are critical for the American ecosystem: from pollinators and seed dispersal to pest control to their cultural and recreational significance, birds are invaluable to us and the world we live in.
We love birds and know our electric cooperative colleagues across the country do, too!
The challenge for electric cooperatives is that birds also like to wreak havoc on wood poles. Birds are notorious for creating holes in electric wood poles, which can lead to significant damage to the poles themselves and the electrical lines they support. This damage can result in costly repairs and pose a serious threat to structural integrity, energy reliability, and the safety of workers and the public.

What Bird Species Cause the Most Damage to Utility Poles?
At the top of the ‘most wanted’ list for bird holes are several species of American woodpecker.
- Northern Flicker: This medium-sized woodpecker is found throughout North America and is known for its distinctive red patch on the back of its head.
- Red-bellied Woodpecker: This medium-sized woodpecker is found across the east and southeast of the U.S.
- Pileated Woodpecker: This large woodpecker is found in forests throughout North America. Pileated Woodpeckers are known for their powerful drilling ability and can create large holes in wooden structures, including electric poles.
- Downy Woodpecker: This small woodpecker is found throughout North America and is known for its black-and-white plumage. Downy Woodpeckers are known to drill small holes.
- Hairy Woodpecker: This medium-sized woodpecker is found throughout North America and is similar in appearance to the Downy Woodpecker, but larger. They are known to drill small to medium-sized holes.
The main issue with birds creating holes in electric wood poles is the weakening of the structure.
- These holes allow moisture to enter the pole, which can cause rot and decay, leading to further structural damage. Additionally, the holes created by birds provide access points for other animals, such as squirrels and rats, which can further damage the pole and the electrical lines.
- The damage caused by bird holes in electric wood poles can be particularly severe during harsh weather conditions, such as high winds, ice storms, and heavy rain. During these events, weakened or compromised poles can be knocked down, leading to power outages and potentially dangerous situations for nearby residents.
How Much Damage to the Utility Pole is Too Much?
One common question we receive: At what size does a bird hole pose a serious problem for a wooden utility pole?
The size of a bird hole that could cause an electric wood pole to fail can differ depending on several factors, such as the pole’s age, condition, the hole’s location, and the weather’s severity.
In general, a bird hole that is more than two inches in diameter can compromise the structural integrity of an electric wood pole, especially if the hole is located in a critical area of the pole or if there are multiple holes in close proximity to each other.
However, it’s important to note that even smaller holes can lead to moisture penetration and decay, which can weaken the pole over time and make it more susceptible to failure during high winds or other extreme weather events.
Regular inspections of electric cooperatives’ poles are crucial for identifying damage caused by birds or other factors. Early detection of woodpecker holes or other damage can allow for timely repairs or replacement of the poles, ensuring the safety of workers and the public while preventing costly repairs.
To proactively prevent bird damage, electric cooperatives should consider conducting regular inspections of the poles to help identify early signs of damage caused by birds and allow for timely repairs.
