BACKGROUNDChristmas bird counts occur in a 15-mile diameter circle. The Lakeland and Lake Wales counts in Polk County are among 2,300 nationwide. Counts are conducted by volunteers, who break up into groups to count all of the birds they find in each territory they cover. Their territories are coordinated by the count's compiler. Some participants also watch birdfeeders and report species such as finches and hummingbirds that are seen there. The count compiler is responsible for assembling the data collected during the count, including the amount of time each team spends in the field, and submitting it as part of the national database, which includes information not only on the number of birds observed, but also the amount of effort devoted to the results. That information is useful to fairly analyze long-term trends.
