Global Big Day took place on Saturday, May 9, 2020!
Cornell Lab of Ornithology’s Global Big Day is an annual celebration of birds marking International Migratory Bird Day by bringing together birders from approximately 170 countries and every continent except Antarctica. Birders submit their sightings through virtual checklists on eBird, the world’s largest citizen-science project.
In birding parlance, a “Big Day” is when an individual or group devotes an entire day to finding and identifying as many birds as possible. Interest in birding has increased due to the stay-at-home orders in place across the country.
Last year on May 4, Cook County birders submitted 683 checklists, finishing second nationally.
Not near a natural area? Local park closed? No problem! Submit your checklists from your front yard, back yard or street! All checklists are welcome and add to the world’s largest citizen science effort. *Please adhere to all social distancing guidelines.*
How to join the effort
Sign up for an account on Cornell Lab of Ornithology’s eBird site (www.ebird.org) or download the eBird app from the Apple Store or Google Play. Record your sightings—create a new Personal Location for your home (simply zoom in on the map and double-click). Or record your sightings for an existing Hotspot. Better yet, do both! Multiple checklists are welcome and will help us achieve the record.
Take a video or photo of your sightings, and then share it on social media. What was cool about your sighting? Where were you? What town? What street?
