It鈥檚 the event of the season鈥攆or avian enthusiasts, that is.  Across the Western Hemisphere, around 80,000 volunteers take part in the Christmas Bird Count (CBC) each year, tallying birds from December 14 to January 5. And there鈥檚 always room for more.

鈥淵ou don鈥檛 have to be an expert birder to join,鈥 says Cooper Farr, 探花精选鈥檚 community science manager. Organizers welcome newbies to help cover established routes within a 15-mile diameter circle on a particular day during the three-week window. 鈥淲e get more circles each year, and the more data we have to track bird populations during the winter, the better.鈥

The trove of information gathered over the CBC鈥檚 125-year history provides insight into the health of bird populations and helps guide conservation action. While the data are serious stuff, gathering them is a blast. There鈥檚 camaraderie, friendly competition, and plenty of opportunity for first timers to socialize with other birders and learn from them. 鈥淚t鈥檚 a big day, and very fun,鈥 Cooper says. Here鈥檚 how to make the most of the tradition. 

Choose Your Adventure 
鈥淓ach count has its own unique flavor,鈥 Farr says, and may include options to bird by car, foot, boat, or ski or to monitor your feeders if you live within a circle. Visit audubon.org/cbc to find a circle near you, then simply email the compiler and tell them you鈥檇 like to participate. 鈥淐ompilers are usually very happy to work with folks and make sure that they feel comfortable and can participate,鈥 Farr says.

Get Ready
A few days before the count, consider checking and/or scouting your route to get a sense of the birds you will likely see. Such preparation is helpful but not necessary鈥攗nlike preparing for the weather. Day-of, check the forecast before you leave your home. If you鈥檒l be out in cool conditions, pack hand warmers, hot drinks, and most importantly 鈥渄ress warmer than you think you鈥檒l need to, because birders move slowly,鈥 Farr says. And whether your CBC is in Canada, Colorado, or Colombia, be sure to bring layers and plenty of water and snacks. 

Go Get 鈥橢m 
Don鈥檛 stress鈥攏obody expects novices to be ID whizzes. You鈥檒l be paired with experienced counters who are familiar with the terrain and the birds usually found in the area. The goal is to record as many birds as possible, so your extra set of eyes and ears are useful for adding to the tally; if you aren鈥檛 sure of the species, your partner(s) will likely know it. Whether you join a count for a partial or full day, bird in a group or at the feeder in your yard: If there鈥檚 a post-count potluck or gathering, go! It鈥檚 where everyone swaps stories and celebrates their joint effort.
