History of the Christmas Bird Count
From the National Audubon Website: How the count started, and how the data is used today.
Prior to the turn of the 20th century, hunters engaged in a holiday tradition known as the Christmas "Side Hunt." They would choose sides and go afield with their guns—whoever brought in the biggest pile of feathered (and furred) quarry won.
Conservation was in its beginning stages in that era, and many observers and scientists were becoming concerned about declining bird populations. Beginning on Christmas Day 1900, ornithologist Frank M. Chapman, an early officer in the then-nascent Audubon Society, proposed a new holiday tradition—a "Christmas Bird Census" that would count birds during the holidays rather than hunt them.

This will be the 119th annual Audubon Christmas Bird Count., with some 2,500 count circles involving close to 70,000 volunteers. Kitsap Audubon has been conducting annual CBCs for 45 years. Last December, we had more than a hundred volunteers counting birds in 15 field teams. The data is used by wildlife scientists to monitor trends and gauge the effects of climate change on shrinking winter ranges
