Each February, for four days the world comes together to admire birds during the Great Backyard Bird Count (GBBC). Participants spend time in their favorite places observing and counting as many birds as they can find and report their findings. This helps scientists better understand global bird populations. We hope you'll join us this year!

Facts About GBBC

• The event began in 1998 as an annual bird count in North America and runs each February.

• A February count allows for a snapshot of birds right before one of their annual migrations.

• In 2013, GBBC became an international event and data was collected using eBird.

• Data from GBBC accumulates in the eBird database. Each year more than 100 scientific publications use eBird data for conservation.
