Ready, set—BIRD! It’s time to flock together for the season’s biggest day of birding!

Get ready for a spectacular October Big Day (OBD)! This annual event, falling on Saturday, October 11, 2025, coincides with World Migratory Bird Day (WMBD) and is a thrilling celebration of our feathered friends and the vibrant birding community.

At BirdsCaribbean, we eagerly anticipate October Big Day. This massive citizen science event is a wonderful opportunity for us to unite with fellow bird lovers to share in the joy of birdwatching and the beauty of Caribbean wetlands, forests, botanical gardens, and neighborhoods. This is our chance to celebrate Caribbean birds, support science, and strengthen our conservation efforts. 

October 11 is truly the moment to puff out our chests and rack up those eBird checklists! 

And there’s more! Global Bird Weekend runs from October 10 to 12, offering even more opportunities to engage and possibly set new world records. Last year, we saw record-breaking participation during Global Bird Weekend — more than 750,000 people from 202 countries submitted 99,317 checklists with eBird — and we’re aiming to surpass that achievement this year. 

Let’s make birdwatching history together!

OBD guide for first timers

Welcome and we’re so happy you’re considering spending Saturday 11th October with the birds! Who knows, maybe this will be where your birdwatching lore begins? OBD is a citizen science initiative spearheaded by the Cornell Lab of Ornithology. Scientists team up with members of the public, called citizen scientists, to collect data on birds from midnight to midnight in their local time zone on October 11; or to bird anytime during the weekend of October 10-12 for the Global Bird Weekend. 

Data sounds intimidating, doesn’t it? Luckily, it ab-so-lute-ly isn’t. Data here means the checklists of birds you see and hear. Spot a blackbird hopping along your fence? That’s data! Hear a bananaquit tsit tsit tsit-ing in your mango tree? You got it — that’s data too! 

But your data must be submitted via the eBird app or website to count. If you do not already have a free eBird account,, it’s easy to sign up — and here’s a quick guide on how to use eBird. The handy mobile app allows you to seamlessly keep and submit lists, in-the-moment, all while you’re out birding — perhaps exploring nearby hotspots. It will even track how far you have walked while watching birds. 

Remember to submit your eBird checklists before October 14, 2024 to be included in the initial results announcement!

Checklists for conservation

Every checklist submitted gives scientists at the Cornell Lab of Ornithology and beyond real-time, worldwide insights into bird populations, migration patterns, and important habitats that might be at risk. Without the collective effort of birdwatchers like you, gathering such a vast and diverse dataset would be impractical, making your participation essential to understanding and protecting birds in the Caribbean and across the globe.

The information you collect and share helps paint a clearer picture of how bird populations are faring in the face of devastating existential threats, like habitat loss and climate change. By identifying where birds are thriving or declining, conservationists can make informed decisions about where to focus their efforts, implement protective measures, and advocate for policies that safeguard these species. Ultimately, your observations translate to the protection and survival of birds — but they also form part of your legacy, part of the mark that you chose to make on the world. A legacy of care ensures that future generations can continue to enjoy the beauty and diversity of our beloved birds. 

Some additional tips from the OBD veterans:

• Check your checklists: By submitting complete checklists of the birds you see and hear you give scientists a comprehensive understanding of the bird community in your area.  Counting birds is easy until you encounter a large flock…of mixed species of birds! Keep calm and check out eBird’s advice on how to count big flock of birds, multiple flocks, or big groups of mixed species here. You also want to keep multiple checklists throughout the day. The shorter the duration and distance of your checklist, the more valuable your data becomes. Long checklists that cover large areas make it hard to pinpoint exactly where and when birds were present.
• Make connections: Birdwatching can be a peaceful solo activity, like a serene stroll through the forest punctuated by bird sightings. But it’s also a fantastic social experience, providing a great way to meet like-minded friends! And there’s so much to learn from fellow birders — they can help with spotting and identifying birds (especially those tricky warblers), and will even help you navigate the eBird app and submit your very first eBird checklist! 

Connect with your local environmental or birding club — there’s a good chance someone is organizing a birding event for October Big Day on your island, and they’d be thrilled to have you join in!

• Don’t wing it: Make a to-pack list and use a backpack. Remember to pack your field guide, stylish and functional BC buff, medicine, water, and food too! If you’re birding in an unfamiliar place, make a trip plan. Be sure to consider where you might park your car, the amount of time you plan to spend birdwatching, how far you want to walk, and tell your friends and family about your plans and where you will be.
• Embrace being a beginner birder: If you’re a newbie don’t let anxiety keep you from discovering the wonderful world of birds. Early mornings are perfect for spotting warblers, while raptors soar as the day heats up. Seagulls and shorebirds are ever-present, and you might catch tanagers and bullfinches at their most active during the late afternoon.
