Count Birds for Christmas!

Every holiday season, tens of thousands of volunteers, mostly in the U.S. and Canada, but also in at least 15 other countries, brave cold, rain, wind and snow to participate in the Christmas Bird Count. The data they gather are used to assess the health of bird populations and guide conservation actions.

What they are

Sponsored by the National Audubon Society, Christmas Bird Counts are held each year between December 14th and January 5th. Their basic purpose is to census bird populations. Each regional count covers a “count circle” 15 miles in diameter, or about 177 square miles. Participants divide into small groups, and each group covers a specific assigned portion of the circle as thoroughly as possible. They identify and count, to the best of their ability, every bird seen during their 24 hour count date. Participants may count birds all day, or for only a few hours. Some prefer to watch their feeders and report those results. Usually one person serves as coordinator, organizing participation, compiling data, and submitting final results to National Audubon.

How they started

Attitudes toward, and appreciation for, wildlife and conservation in this country have changed drastically over the years. In the 19th century, before there were laws protecting migratory birds, “side hunts” were a popular holiday tradition. Contestants would choose sides and see how many birds and other animals a team could shoot in a single day. Frank M. Chapman, a young ornithologist and early officer in the newly formed Audubon Society, was outraged by this senseless killing and waste of wildlife. In protest, on Christmas Day 1899, he counted live birds for three hours, publishing his results in the newly created Bird-Lore magazine (which later became Audubon), and encouraged other bird lovers to do the same. The next year, 1900, the first national count was held, with 27 participants counting in 25 locations across the U.S. and Canada.

Each year since then, the Christmas Bird Counts, or CBCs, have grown. Well over 2,000 regional counts are now held, with over 70,000 participants. About 40 are held in North Carolina. This year’s 116th annual count promises to be the biggest yet. The Raleigh CBC, sponsored by Wake Audubon, will be held on Saturday, 19 December 2015.

Why they’re important

CBCs are among the best data sources we have on bird populations. They can depict trends and population fluctuations over time. They are also the best-known citizen science projects in the world—allowing ordinary citizens to gather data that contribute to the overall body of our knowledge about birds. The counts certainly have their flaws and shortcomings. Not every part of a count circle can be covered. Certainly not every bird gets seen or identified. Large flocks can’t be counted precisely. It’s hard to be sure that some birds don’t get counted more than once. But the sheer volume of information and the consistency of holding the counts in the same places, during the same seasons, often with the same participants counting in the same fashion, year after year, make the data very valuable. Studies have shown that CBC data correlate closely with those gathered using more rigorous scientific methods. Hundreds of peer-reviewed articles have been published in scientific journals using analyses done with CBC data. State and federal agencies also use the information to make important bird conservation decisions.

Why they’re fun

CBCs are good opportunities to learn about birds from skilled and knowledgeable birders. They are also social events, where birders can make new friends, or spend time with old ones. These are the biggest reasons that many people participate. Many counts have special traditions, including lunches, dinners, and countdown parties during which data are compiled and stories are shared. Some even have their own T-shirts. The Raleigh CBC’s annual potluck dinner, the venison chili and pralines usually to be had at the Southern Pines count, and the Key lime pie and seafood featured at the tally rally following the Ocracoke and Portsmouth counts, will be enough to keep you coming back. But even better are the things you’ll see and learn, and the friends and memories you’ll make.

If you don’t know birds very well, you can still be placed with a team of good birders and help by spotting birds for them to identify, or by helping them keep their list. Birding with experts is one of the best ways to learn. Even if you don’t participate in an organized count or project, birding is fun and educational in its own right, and is one of the easiest outdoor activities to get interested in, because you can watch birds anywhere. A pair of binoculars and a good field guide are all you need to get started. And you have all year to learn and practice for those Christmas Counts!
