As smoky air becomes more common during Washington’s wildfire season, many wildlife enthusiasts wonder: What happens to the birds? Few studies have looked at wildfire smoke impacts on animals, let alone birds. And as Washington and the larger West Coast continue to experience more massive wildfires and smoke-filled air, understanding how birds are affected by smoke — and how air pollution may influence our ability to detect birds — are important factors for bird conservation. Researchers from the University of Washington now 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 actually easier to detect when smoke was present. The results were published June 29 in the journal Ornithological Applications.
