Christmas Bird Count (CBC) season is upon us again! This is a great time to join others and cooperate in a massive effort across the Western Hemisphere to take a snapshot of bird occurrence around the holidays. For three weeks each year (14 December to 5 January) tens of thousands of birders head out to conduct the Audubon CBC. These counts are cooperative efforts to get the best count of birds in a single 15-mile diameter circle. They depend upon the efforts of multiple parties of observers with each group checking different parts of the count circle, combining for a final count total that can be compared to totals for the past 118 years to help understand changes in bird populations.
