Christmas Bird Count

The Christmas Bird Count (CBC) is a hemisphere-wide effort coordinated by the National Audubon Society to monitor populations of birds on their wintering grounds. Each year volunteers count individuals of all species seen or heard within an established 15-mile-radius circle on a single day in late December or early January. Because the effort in counting varies each year, records are kept of the number of observers, parties working together, and party-hours and party-miles spent on foot or in cars. Nearly 40 count areas are surveyed each winter across Alaska. Each year the results are published in American Birds, and summaries can be found on the CBC website.
