At the annual Great Backyard Bird Count (GBBC), bird watchers from all over the continent gather to count birds and create a real-time snapshot of birds’ whereabouts across the continent. The data are used by scientists studying bird populations.
Bird watchers of all ages can count for as long as they wish during this four-day period. In order to report their counts, they fill out an online checklist at the GBBC website.
