There are 16 sites in the state where Christmas Bird Counts are held each year, Howery said. Among them are the Red Slough in far southeastern Oklahoma, where 120 species of birds were documented on last year's count, the most in Oklahoma.
The Chickasaw National Recreation Area in Sulphur is holding its first Christmas Bird Count this year.
Oklahoma City, Tulsa and the Tishomingo National Wildlife Refuge also produce numerous sightings on annual Christmas Bird Counts.
“Over time, a sense of competition kind of builds,” Howery said. “You have competition between people within a Christmas Bird Count and competition between the different Christmas Bird Counts.”
