According to researchers and news reports from 2014 to 2018, at least 44 confirmed cases of wildfires were sparked by electrocuted birds in the United States alone.1
As climate change continues to create tinderbox conditions in many regions, the risk of these avian-caused wildfires is only expected to rise. However, the challenges are daunting with vast power grids to modify and limited resources available.
Can we act fast enough to protect our feathered friends and communities from this unexpected threat? The race is on to find answers before the next spark ignites a catastrophic blaze.
The Science Behind the Sparks
So, how exactly does a bird become a fiery projectile? It all comes down to the physics of electricity. When a bird simultaneously touches two wires of different voltages or a wire and a grounded object like a utility pole, it creates a path for the current to flow through its body. (ref)

The result is a gruesome fate for the bird, as the intense heat can cause its cells to explode and its feathers to ignite.
Due to their size, larger birds with wider wingspans, such as eagles, hawks, and vultures, are particularly vulnerable to electrocution. As they take off or land on power lines, their wings can easily bridge the gap between two wires and a pole.
This risk is amplified in areas with sparse vegetation, where utility poles often provide the only suitable perching spots for these majestic creatures.
Hot Spots & High Stakes
While bird-caused wildfires have been reported nationwide, some regions feel more heat than others. Colorado and Idaho have emerged as hot spots, with several fires attributed to electrocuted birds in recent years. (ref)
The consequences of these fires can be severe, threatening homes, wildlife habitats, and human lives.
In 2015, a single bird-sparked blaze in Idaho burned through 10,000 acres and required the efforts of 165 firefighters to contain. As climate change exacerbates drought conditions and lengthens fire seasons, the stakes have never been higher.
Seeking Solutions
Utility companies and wildlife organizations are now searching for ways to prevent these avian electrocutions and the resulting wildfires. Some solutions include installing bird deterrents on power lines, such as plastic spirals or spikes, to discourage perching.
Insulating wires and redesigning utility poles to provide safer perching spots away from energized components are also being explored. However, implementing these measures across vast power grids is daunting and costly.
Many utility companies struggle to balance the need for bird protection with the financial realities of upgrading aging infrastructure.
As the threat of wildfires grows, finding effective and economically feasible solutions has become a pressing concern for all involved.
A Call to Action
As we grapple with the complex challenges of climate change and wildlife conservation, bird-caused wildfires serve as a sobering reminder of our ecosystems’ interconnectedness.
It is a call to action for utility companies, policymakers, and the public to collaborate on innovative solutions to protect our feathered friends and communities.
By raising awareness about this overlooked threat and investing in bird-safe infrastructure, we can help prevent the tragic loss of life—both avian and human—and preserve our natural heritage for future generations.
