More than three dozen fires started from electrocuted birds in the United States from 2014 to 2018, according to the most comprehensive analysis yet of such blazes.
. A year later, a blaze in Idaho burned more than 4000 hectares, an area nearly 12 times the size of New York City’s Central Park. Both conflagrations had one thing in common: Experts believe they were started by birds.
More than three dozen fires started this way in the United States from 2014 to 2018, according to the most comprehensive analysis yet of such blazes. “The ecological and economic losses are substantial,” says Antoni Margalida, a conservation biologist at the Pyrenean Institute of Ecology who has studied the impacts of wildfires caused by birds and other fauna in Spain but who was not involved with the work.. Lightning and even heat from the Sun can also spark blazes.
The scientists then discounted any speculative reports, only keeping those with evidence of a bird as the cause. These could include a photograph of a burned bird carcass at the fire’s ignition site, or a statement made by an expert, such as a firefighter, detailing the presumed cause of the fire. Finally, they checked to see whether any particular environment was especially susceptible to these fires..
The wildfires reported in the study were generally small: Most of them burned about 1.2 hectares, a touch over two U.S. football fields. Yet there is a clear potential for large-scale devastation, as the Idaho and Chile fires show.of the 235 birds electrocuted there in 2018, 15% were species of conservation concern such as the steppe eagle and the Egyptian vulture .
