On 9 May, birding’s biggest day is back! 

Global Big Day is an annual celebration of the birds around you, and this year is no different. While not everyone may be able to leave home to bird this year, Global Big Day is still an opportunity to check in with the birds in and around where you live. Join us on 9 May and be a part of a global birding community by sharing what birds you see around you with eBird. 

Participating is easy. Wherever you are, you can be a part of the global community of birders on 9 May. Please remember to always put safety first and follow all local safety guidelines and closures. You can enjoy birds from inside your home and still be part of Global Big Day. 

If you can spare at least 5 or 10 minutes, report your observations to eBird online or with our free eBird Mobile app. If you have more time, submit checklists of birds throughout the day at different times. Can you find more birds in the morning, or the evening? You never know what you might spot. Your observations help us better understand global bird populations through products like these animated abundance maps brought to you by eBird Science.

This year, Global Big Day will focus  on the number of checklists we can collect as a global team. Last year, 35,209 eBirders from 174 countries collected an astounding 92,284 checklists in a single day. Will you join us on Global Big Day to make 2020 the year that we surpass 100,000 checklists of birds in one day? Help us set a new checklist record!

How to participate

  • Get an eBird account: eBird is a worldwide bird checklist program used by millions of birders. It’s what allows us to compile everyone’s sightings into a single massive Global Big Day list—while at the same time collecting the data to help scientists better understand birds. Sign up here. It’s 100% free from start to finish.
  • Watch birds on 9 May: It’s that simple. You don’t need to be a bird expert or go out all day long, even 10 minutes in your backyard counts. Global Big Day runs from midnight to midnight in your local time zone. You can report what you find from anywhere in the world.
  • Enter what you see and hear in eBird: You can enter your sightings via our website or download the free eBird Mobile app, which makes adding what you see even easier. You can enter and submit lists while out birding, and the app tracks how far you’ve walked so you can focus on enjoying the birds. While you’re downloading free apps, try out the Cornell Lab’s Merlin Bird ID app for help with identification. Please enter sightings before 13 May to be included in our initial results announcement.
  • Watch the sightings roll in: During the day, follow along with sightings from more than 170 countries in real-time on our Global Big Day page.

Contributing sightings is easy with the free eBird Mobile app. Download for iOS or Android.
