The top 100 birders in Delaware County submitted 213 species and submitted 2433 separate checklists. Way to go!!! And I know there a several good birders whose lists aren't counted. Maybe they will add their sightings next year. (Hint, Hint)
Delaware County data sets for bar chart and other eBird status & distribution characterizations were greatly increased in 2016 by the record participation of birders by/for whom data was entered. Thanks to all of you!
