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 and in Hawaii. 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.
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 us 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?
Scientists use the counts, along with observations from other citizen-science projects, such as the Christmas Bird Count, Project FeederWatch, and eBird, to give us an immense picture of our winter birds. Each year that these data are collected makes them more meaningful and allows scientists to investigate far-reaching questions.
Please consider participating in this years Great Backyard Bird Count!
