“On May 9th this year will be the first Global Big Day, and the idea is to see, if we have people all around the world on a single day looking for birds, how many birds can we find in 24 hours.”

Chris Wood of the Cornell Lab of Ornithology, in Ithaca, New York. He’s the project leader for eBird. It’s an online database by which birdwatchers anywhere on the planet can upload their sightings and help increase the resolution of our information on exactly what birds are hanging out where, and when. I spoke with Wood on a visit to the lab in April. What are called Big Days have been local events for counting birds. But the May 9th Big Day is for the whole world.

CW: “So the hope is that people in India, people in Iran, people in Australia, many of whom are already using eBird, will enter birds that day and see if we can find 3,000 species, 4,000 species. That’s really the idea. It’s one day to go out and explore biodiversity and see this amazing planet that we live on.”

SM: “And is there going to be any kind of working up of that data for a particular reason?”

CW: “Yeah, so what we’ll do is we ask everybody to enter data into eBird. And by having those data in eBird will give insight into populations of birds at some level, but it also just allows us to prioritize and think about, okay, here’s a region of the world where despite these outreach efforts, we haven’t engaged as  many people. And it allows us to help, so we think, okay, for the next year let’s focus here and see if the next year all of a sudden the birds that are on Fiji, maybe, if we have reports of them, and then the idea really is to inspire people to not just count birds on this one day, but really to count birds every week or every day and then really understand about how ecosystems are functioning, how birds are moving across the landscape.”

SM: “So Global Big Day is a way for people to count birds, but for you to count people.”

CW: “Yeah, at some level.”

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,
