Christmas Bird Count

The Audubon Christmas Bird Count is the longest running Citizen Science Wildlife survey in the world with the first count in 1899.  Each year, tens of thousands of participants collect and submit bird data to the National Audubon Society for use in assessing the health of bird populations and for guiding conservation efforts.  It is vital in the study of bird population trends.

Yellowstone Valley Audubon Society joined the national efforts in December 1953, the same year YVAS became a chapter.  This annual event includes recording the number of birds and bird species seen within a designated route in the Billings vicinity.  After a no-host breakfast at a local diner (optional), YVAS birders head out on their routes to identify and count species.  This is followed up with a traditional soup dinner in the afternoon as the results are tallied.

If you are interested in being a part of the longest running wildlife census on record, watch for details in the November/December Flyer.  There is always a need for more birders of all abilities to help count and record.  This is a great time for beginning birders to learn the winter species in the Billings area.  For more information, contact Jim Court at 406-259-5099 or at
