Are you ready to join in the biggest, most important spring day of birding with more than a million birders from across the country and around the world? The Global Big Day is coming up Saturday May 9th, when birders around the world will identify, count, and report the birds they see – anytime, anywhere that Saturday. Last year birders in 204 countries and sub-regions joined together during Global Big Day to report a record number of 8,039 different species of birds! Birders demonstrated the power of their collective action and showed that Global Big Day is officially more than a day of birding together – it's a movement!
Everyone should be interested in participating, from long-time birders to first-time beginners, because everyone who joins the Global Big Day celebration makes a difference in the information gathered. And it's easy to join the action: Simply enjoy birding for any period of time you choose from 15 minutes to 15 hours, anywhere you choose during Global Big Day where you identify and count all the birds you see, then report your list to eBird online.
You can participate as a group of friends, a family, a team, or on your own – anytime, anywhere, for as long as you wish on Saturday May 9th. You can even report on the birds you observe at a number of locations – at home, a favorite marsh, a woodland grove, or a mountain hideaway – it's easy and fun to be part of this exciting worldwide event!
