How many birds can be seen in one day? Traditional birding ‘big days’ focus on the species total of a single team of birders: how many birds can be seen by one carload of birders for a midnight-to-midnight birding binge. Imagine if the entire world joined together as one team, how many birds could we see? Global Big Day answers that question.
For three years in a row, Global Big Day has set a progressively bigger world record for the number of birds seen in one day, with more than 20000 birders contributing sightings from 160+ countries last year. On 5 May 2018, we want you to be a part of birding’s next world record. All you have to do is to spend a few minutes outside on 5 May, anywhere in the world, and submit it to eBird. Every sighting counts.
If you’re new to eBird, don’t worry! We recommend checking out the Merlin Bird ID app to help with identifying your birds, and the eBird Mobile app makes it easy to note what you find and join in the fun.
No matter what you do—have fun, enjoy the birds you find, and share your sightings on eBird! Can we we surpass last year’s result, of 6637 bird species, and set a new record for one day of birding? It’s in your hands. We’re excited to see what we can achieve together for Global Big Day.
How to participate
Submit your data to eBird on 5 May
It’s that simple. If you submit your birds to eBird they count. Use the website or mobile app, whichever you prefer. Learn how to take part. Don’t worry — you don’t need to be a bird expert, or to go out all day long. Even ten minutes from your backyard will help. Of course, you are welcome to spend the entire day in the field, but know that it is not required! Please enter your data as soon as you can, preferably by Tuesday, 8 May.
