National Audubon's Christmas Bird Count (or CBC, as its known to seasoned pros) is the nation's longest-running citizen science bird project. Over a century's worth of data has been collected since the project began, and now its as much of a tradition for many friends and families as it is a massive scientific project. Data from the Christmas Bird Count has been used in countless important research discoveries, including National Audubon's landmark Birds and Climate Change study.

Carl Lundblad's advice on CBCs and entering eBird data:
Because CBC season is upon us, this is a good time to review best practices for entering your CBC data into eBird.

One important point, is that distance covered is reported differently for CBC than eBird counts. For the CBC, you are asked to submit the total distance traveled, even if this includes back-tracking over the same ground. eBird checklists should only include the "one way" distance, so that if the same ground is covered more that once during the count, the distance should only be reported once on the same checklist. This becomes less of an issue if you split your CBC count into many separate location-specific eBird checklists (some of which might represent multiple stops at particularly-productive locations), which generates much higher-quality data for eBird.
Happy Counting, Happy Holidays, and Good Luck.
