ESCANABA — Back in the 1800s, hunters engaged in a holiday tradition known as the Christmas “side hunt,” where teams competed to bring back the largest pile of feathered (and furred) game. When the conservation field began to emerge in the late 1800s – and hunters, bird watchers and scientists were developing a growing concern for declining bird populations – other options emerged, too.

On Christmas Day 1900, Frank M. Chapman, an early officer of the National Audubon Society, proposed a new holiday tradition: a “Christmas Bird Census” to count, rather than hunt, birds during the holidays. This marked the beginning of the Audubon Christmas Bird Count!

In its first year, 27 volunteers conducted 25 CBCs across locations from Toronto to California, tallying 90 bird species. This year marks the count’s 125th year, making it the longest-running bird census in the hemisphere. Dec. 14 to Jan. 5 every season across the Americas, tens of thousands of volunteers participate to gather critical data that helps scientists protect birds and the places they need.

That information allows researchers, conservationists and wildlife agencies to study long-term trends in bird populations across the Americas. When combined with other surveys, such as the Breeding Bird Survey, these data provide insights into how bird populations have changed in time and space over the past century. Audubon and other organizations use these findings to guide conservation efforts for birds where they are most needed.

In Michigan, dozens of local Audubon chapters organize CBCs. Many counts include guided bird walks, making them great opportunities for new birders to gain experience and connect with others who share their interest. The Christmas Bird Count is a prime example of how everyday observations from first-time volunteers and experts alike can make a big difference.
