More than 160,000 people of all ages and walks of life worldwide join the four-day count each February to create an annual snapshot of the distribution and abundance of birds. We invite you to participate! For at least 15 minutes on one or more days of the count, February 15-18, 2018, simply tally the numbers and kinds of birds you see. You can count from any location, anywhere in the world. Sign up online and help scientists learn how birds are affected by environmental changes.
