Be a part of something big!

The Great Backyard Bird Count is an annual four-day event that engages bird watchers of all ages in counting birds to create a real-time snapshot of where the birds are across the continent. Anyone can participate, from beginning bird watchers to experts. It takes as little as 15 minutes on one day, or you can count for as long as you like each day of the event. It’s free, fun, and easy—and it helps the birds. We’ll be adding updated GBBC materials for the next count as they become available.

Participants count birds anywhere for as little or as long as they wish during the four-day period. They tally the highest number of birds of each species seen together at any one time. To report their counts, they fill out an online checklist at:

Why Count Birds?
Scientists and bird enthusiasts can learn a lot by knowing where the birds are. Bird populations are dynamic; they are constantly in flux. No single scientist or team of scientists could hope to document the complex distribution and movements of so many species in such a short time.

Your counts can help them answer many questions:
•    How will this winter’s snow and cold temperatures influence bird populations?
•    Where are winter finches and other “irruptive” species that appear in large numbers during some years but not others?
•    How will the timing of birds’ migrations compare with past years?
•    How are bird diseases, such as West Nile virus, affecting birds in different regions?
•    What kinds of differences in bird diversity are apparent in cities versus suburban, rural, and natural areas?

•    Are any birds undergoing worrisome declines that point to the need for conservation attention?

The Great Backyard Bird Count is led by the Cornell Lab of Ornithology and National Audubon Society, with Canadian partner Bird Studies Canada and sponsorship from Wild Birds Unlimited.
