Since 1951, the OOS has served as a place where recreational birders and academics interact to increase appreciation and conservation of wild birds in the Sooner State. The OOS sponsors field trips, semiannual meetings with invited guest speakers, a quarterly newsletter (The Scissortail), and a quarterly peer-reviewed state journal (The Bulletin of the Oklahoma Ornithological Society).

Christmas Counts

Audubon's 121st Christmas Bird Count will be conducted between the dates of Monday, December 14, 2020 through Tuesday, January 5, 2021. 


The CBC is an early-winter bird census, where volunteers follow specified routes through a designated 15-mile (24-km) diameter circle, counting every bird they see or hear all day. It’s not just a species tally—all birds are counted all day, giving an indication of the total number of birds in the circle that day. Each count is conducted in one calendar day.

There are about 16 CBCs held each year in Oklahoma. A comprehensive list of all statewide CBCs, along with other CBC resources and information, can be found on the Tulsa Audubon site at:
