Every year birders across the world trek out into the rain, sun, sleet, or wind to participate in the Christmas Bird Count, organized by the National Audubon Society. The massive community science project, in its 124th year, tracks bird population fluctuations from year to year. This year’s count runs from December 14 to January 5.

Ira and guest host Flora Lichtman are joined by Ariana Remmel, a birder and freelance journalist based in Little Rock, Arkansas, and Dr. Anuj Ghimire, a birder and wildlife ecologist at North Dakota State University. They give a preview of this year’s Christmas Bird Count and take listener questions. 

Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
