How many bird species can be seen in York County in a single year? A dedicated birder can tally 200 or more with reasonable effort, but what if a bunch of birders ranging from casual watchers to serious listers contributed to a single collective list? They have, on eBird, and the 2010 total was 298. [Edit: Not so fast! See my followup on what eBird counts as “species.”]
eBird.org is a real-time online checklist program launched in 2002 by the Cornell Lab of Ornithology and National Audubon Society. It makes vast numbers of bird observations accessible and usable. We’re watching the monthly lists for York County and will report what we find in The Harlequin. Watch the next issue to learn how you can share your bird records.
