Running since 1900, the Christmas Bird Count (CBC) is the nation's longest-running community science project, and the resulting data fuel our work.

From December 14 through January 5, tens of thousands of volunteers throughout the Americas brave snow, wind, or rain to take part in the effort. By counting birds in designated areas, these volunteers have helped to create an extensive ornithological database that sheds light on the health of wild bird populations, helps with the tracking of environmental changes at local and hemispheric scales, and informs our work protecting birds and the places they need.

Individual counts take the form of 15-mile diameter circles and teams with teams of volunteers taking on predetermined sections. While section leaders are tasked with ensuring the full coverage of their assigned area, individual volunteers can put in as much or as little effort as they wish. They may spend the day on foot from dawn to dusk roaming a remote section, or they may spend just the morning monitoring a feeder station. They may cover vast distances by vehicle, or they may focus on a small yet productive hotspot. The opportunities are varied, and all birders expert or new are welcome to join the effort!

To do our part to contribute to this annual effort, Appleton-Whittell Research Ranch staff manages the Appleton-Whittell CBC circle. The circle includes a variety of habitats from the grasslands of the Sonoita Valley to the oak woodlands in the foothills of the Huachuca Mountains and as such offers great birds - grassland sparrows, three species of quail, wintering raptors, and more! As an Audubon-led count, we make sure that opportunities are available for folks of all ages, skill level, and physical ability.
