For example, a casual review of the results shows us that Eurasian Collared-Doves have continued to march northward and westward; participants reported this introduced species from more states (22) and in greater numbers (nearly 3,300) than last year. Likewise, the periodic southward irruptions of Common andHoary redpolls were apparent in the 2004 GBBC. In the southeastern United States, Gulf Coast birders were able to see increased numbers of two other finches, the Pine Siskin and Purple Finch. Results such as these form the raw material for researchers analysis. With each passing year, the GBBC brings new information and adds value to what is already contained in our database, allowing us to build critical information on long-term trends in bird populations. The project, now in its eighth year, is developed and managed by the Lab of Ornithology and Audubon with sponsorship from Wild Birds Unlimited. The GBBC web site provides information for participants, including images, vocalizations, range maps, and tips to help you distinguish among similar-looking species. In addition, participants learn a great deal about birds, and have the option of discussing what they have seen with more than 100 experts around the continent. We encourage those taking part to send in digital photographs of unusual sightings. We will post some of these photographs to the web site during the event for all to share, such as the male Rose-breasted Grosbeak that spent the winter in Derry, New Hampshire, in 2004. Simply email your photograph to citizenscience@audubon.org.

This year, we hope that in addition to counting birds in your own backyard, you ll venture into North America s bigger backyard our national and state parks, wildlife refuges, and other public lands. We re taking the GREAT in the Great Backyard Bird Count very seriously! To participate, simply count the birds you see during all or part of the four-day event and report your highest counts for each species over the Internet at www.birdsource.org/GBBC. Yo u r sightings will be pooled with those of thousands of other birders so you can fit what you see into a bigger picture of bird movements across the continent. As the reports are tracked in real time, you can view maps showing where the birds are being seen and how many of them there are. With thousands of people sending in their information at the same time, birders across North America become linked to one another you ll be able to feel the excitement of being part this huge network of birders, all wired up together at the same time. We ve chosen this year s theme North America s Great Backyard as a way to encourage people to get out and count birds at a time of year when fewer people are visiting our public lands. The GBBC is about gathering information about the movements and numbers of our common birds, as well as of birds of special concern. Since fewer people normally visit national parks, national forests, or wildlife refuges in the winter, you could turn up some very useful information. What are birders able to show through the GBBC?you will encourage others to take part too. The GBBC is a great event for scout troops, classrooms, businesses, and nature clubs, or any group interested in learning about birds together. So put the date in your calendar for February 18 22, look at the web site today at <www.birdsource.org/gbbc>, and call your friends to make a birding date. We look forward to learning from what you see. Paul Green is Audubon s director of citizen science. If you would like to participate in the GBBC but aren t online, try visiting your local library for Internet access or submitting your reports through participating Wild Birds Unlimited Stores. If necessary, you can receive instructions by calling the Lab at (800) 843-2473 and submit reports through postal mail sent to Cornell Lab of Ornithology, Attn: GBBC, 159 Sapsucker Woods Rd., Ithaca, NY 14850. You ll be able to feel the excitement of being part this huge network of birders, all wired up together at the same time.
