Audubon Christmas Bird Count
The Christmas Bird Count: A Global Holiday of Nature, Community, and Conservation
Each December, as snow begins to fall and lights twinkle in windows, a quieter but deeply joyful celebration takes flight across the world, the Christmas Bird Count. It’s not a competition, not quite a festival, yet it brings together tens of thousands of people in every kind of weather to do one simple, beautiful thing: count birds.
From December 14, 2025 to January 5, 2026, families, friends, school groups, and seasoned birders will rise early, bundle up, and step outside, binoculars in hand, to take part in what has become one of the world’s longest-running wildlife traditions.
The Story Behind the Celebration
The Christmas Bird Count, or CBC, began humbly on Christmas Day, 1900. At the time, a popular holiday pastime called the “side hunt” encouraged people to shoot as many birds as possible for sport which was a troubling reflection of a less conservation-minded era. Enter Frank Chapman, an ornithologist and early conservationist with the Audubon Society. Chapman proposed something radical: instead of killing birds, why not count them?
That Christmas, 27 volunteers in 25 locations across North America tallied 90 species. What began as a small act of kindness toward wildlife has since grown into a global citizen-science phenomenon. Over 125 years later, the CBC continues every winter, covering thousands of “count circles” across the Americas and inspiring similar counts around the world.
The Official Date Range
The National Audubon Society, which coordinates the CBC in the Americas, officially sets the window as December 14 through January 5 every year. Each local count circle chooses one calendar day within that window to hold its count. That single day is their official “count day” for that season.
Why Those Dates?
When the event began in 1900, the count was originally held on Christmas Day. As participation expanded, organizers realized: Not everyone could count on the 25th (many people traveled or had family commitments). Bird populations don’t change drastically day to day in winter, so a few weeks of flexibility wouldn’t harm scientific accuracy. So, the date range was broadened to include the period from mid-December to early January, long enough for different regions to pick a convenient day, yet narrow enough that results still represent the same winter snapshot of bird populations.
How Groups Choose Their Day
Though it happens over a three-week period (Dec 14 – Jan 5), each local group chooses one special day to hold its count. Each local compiler (the volunteer organizer) selects a specific day within that period based on: Typical weather conditions (some prefer early dates before heavy snow; others later for holiday schedules), Volunteer availability, and Local bird activity (in some regions, certain winter migrants arrive later in December).
Once chosen, that count circle keeps the same area every year, but the exact day can shift slightly depending on what works best for the local team.
The Heart of the Day
The day becomes a mini-holiday in itself, part outdoor adventure, part social gathering, part quiet reflection. Each group, known as a “circle,” covers a fixed area about 15 miles wide. Volunteers set out before sunrise, bundled in layers, thermos in hand, scanning treetops, fields, shorelines, and feeders.
Throughout the day, they record every bird seen or heard, from chickadees at backyard feeders, flocks of geese over frozen lakes, and a rare hawk cutting through the sky. Some volunteers stay cozy indoors, watching feeders from kitchen windows. Others trek snowy trails, sharing laughter and sightings over walkie-talkies. When the counting ends, participants gather for a warm-up and “tally party,” swapping stories and comparing numbers before submitting data to the National Audubon Society, which coordinates the counts and analyzes the results.
How to Celebrate the Christmas Bird Count
You don’t need to be an expert birder to take part, just curious and observant. Here’s how you can celebrate this unique holiday of nature and community:
Find your local count circle. Visit audubon.org to find the count near you and contact the compiler (the local organizer).
Choose your role. Join a field team or count birds at your home feeder. Both are valuable! Bundle up and bring binoculars. Comfortable layers, sturdy shoes, and a notebook or birding app are all you need.
Make it festive. Many groups turn the count into a holiday tradition, sharing hot cocoa, cookies, and stories after a chilly morning outside.
Share the experience. Post your sightings online, tag your photos with #ChristmasBirdCount, and tell friends about your day. Even if you can’t join an official count, you can celebrate in spirit by spending a quiet winter morning watching your local birds and reflecting on their beauty and resilience.
Why It Matters and Why It Feels So Good
While at first glance the CBC may seem like a fun outing for bird-lovers, but its significance runs much deeper.
A gift to science. The CBC’s continuous record, now over 12 decades long, is one of the world’s most valuable bird-population datasets, guiding conservation policy and climate research. Changes in species abundance, range shifts (northward or to different habitats), and changes in migratory patterns all appear over time in this data. For example, declines in certain waterfowl or shifting abundances of wintering species have been noted. The data feeds into scientific studies, conservation policy, and habitat protection efforts.
A celebration of community. It empowers everyday people, from backyard bird-watchers to dedicated field teams, to contribute to meaningful science. This democratization of bird monitoring builds awareness, engagement, and community. People of all ages and backgrounds join together, learning from one another and finding common joy in shared purpose.
A tradition of hope. At its heart, the Christmas Bird Count is more than just data collection. It’s a holiday of connection between people, nature, and time. Amid a busy holiday season, the CBC offers a grounding reminder that small, simple acts, like noticing a sparrow, can ripple outward into something far greater.
How It Unites People Worldwide
Although it began in North America, the spirit of the Christmas Bird Count has gone global. Similar counts now take place in Central and South America, the Caribbean, and beyond. Each region may adapt it to local traditions, but the heart remains the same: coming together for birds, for nature, for each other. In this way, the CBC has quietly become one of the world’s great inclusive holidays, a celebration without borders or commercialism, where joy comes not from gifts or glitter but from noticing life itself.
A Holiday Worth Keeping
When you step outside on your count day, the world feels still and alive all at once. Breath clouds the air, boots crunch in snow, and somewhere in the silence, a bird sings. That sound connects you not only to nature, but to thousands of others listening and counting across continents. The Christmas Bird Count reminds us that celebration can mean care, that tradition can mean stewardship, and that the holidays can be a time not just for giving, but for truly seeing.
So this December, grab your binoculars, wrap a scarf tight, and join the Christmas Bird Count. Your count, however small, will echo across generations.
