eBirding your Christmas Bird Count


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 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 each checking different parts of the count circle. Compilers add the efforts of the various teams together and assemble a final count total, which can be compared to totals for the past 115 years to understand changes in bird populations. eBird collects data at a finer scale and from single parties of birders, and eBird Mobile makes it easy to keep your tallies through the day. We invite each group to submit their single-party lists to eBird. For guidance on best practices for submitting your CBC to eBird, see these links:
