American Birds 2008-2009, Summary of the 109th Christmas Bird Count
Inclement weather once again played a major factor during the official count period, shaping the overall results of the 109th CBC season. Despite those challenges, and in part due to a continuing CBC presence in Latin America, another record high number of counts was included--2124. And for the first time, a CBC was conducted in Antarctica, adding birds of a new continent to the cumulative database. In addition to overall and regional CBC summaries, feature articles in this season's American Birds include: the documentation of range-shifting of birds across North America and likely effects of climate change; the amazing 400-count (and climbing!) record of an incredibly dedicated compiler and participant (Paul W. Sykes, Jr.); the history of the CBC in New York City's Central Park; a feature on the first count in Antarctica; and 100 years of Christmas Bird Counts in London, Ontario.
