Hidden in the feathers of museum specimens of birds is information on the air quality of past decades - very detailed information. These specimens also contain evidence of the impacts of recent climate change on birds. What do these birds have to say? Join Shane DuBay and Ben Winger of the U-M Museum of Zoology to discuss what bird specimens can tell us about air quality, climate change impacts, and what we can all do to help rapidly declining bird populations now.
