As smoky air becomes more common during Washington's wildfire season, many wildlife enthusiasts wonder: What happens to the birds? Researchers provide a first look at the probability of observing common birds as air pollution worsens during wildfire seasons. They found that smoke affected the ability to detect more than a third of the bird species studied in Washington state over a four-year period. Sometimes smoke made it harder to observe birds, while other species were easier to detect when smoke was present. This research was funded by the National Science Foundation and the McIntire-Stennis Cooperative Forestry Research Program from USDA’s National Institute of Food and Agriculture.
