Hawai’i Audubon Society will be hosting a group meetup on Saturday, May 11 from 9-11am. We will be birdwatching at Hamakua marsh in Kailua, Oahu.

Participants are welcome to do any combination of the following:

  1. Participate in citizen science with eBird (more info below).
  2. Take photographs.
  3. Nature journal.
  4. Birdwatch.

You are also welcome to participate in the Global Big Day on your own. Send us photos and stories if you do!

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 reports into a single massive Global Big Day list—while at the same time collecting data to help scientists better understand birds. Sign up here. It’s 100% free from start to finish.
  • Enjoy birds on 11 May: It’s that simple. You don’t need to be a bird expert or go out all day long, even 10 minutes of birding from home 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 to make submitting lists even easier. Please enter your checklists before 14 May to be included in our initial results announcement.
  • Watch the results roll in: During the day, follow along with bird observations from more than 200 countries in real-time on our Global Big Day page.
If you’re new to eBird or want to make your checklists more valuable for science and conservation, take the free online eBird Essentials course before you go birding on Global Big Day—11 May 2024.
