Each February, thousands of people around the world will count birds and submit their sightings during the Great Backyard Bird Count (GBBC). The 21st annual GBBC will be held Friday, February 15, through Monday, February 18, 2019.

The data collected will provide an instantaneous snapshot of global bird populations that will inform future conservation efforts.

This free, fun, family-friendly weekend is also a great way to introduce birders of all levels to community science. Broad participation is encouraged not matter your location–even if you can only identify one species of bird. Count birds in your backyard, terrace or favorite park!
