American Birds 2009-2010, Summary of the 110th Christmas Bird Count
In keeping with the past several seasons, weather systems again were the big story for the 110th CBC, especially on weekends and especially in the heavily CBC-laden Northeastern region. Yet despite potentially challenging conditions and the re-scheduling or cancelling of a number of counts, for the 110th Count another new record high number of counts was submitted (2160) and additionally a record high level of participation was reached (60,753 observers). Coverage in Latin America continues to increase; there are now more Christmas Bird Counts in Colombia than any other country after the United States and Canada.
In addition to overall and regional CBC summaries, feature articles in this season’s American Birds include: the importance of citizen science to bird conservation; the challenges and rewards of CBCs in the Polar regions; an initial summary of CBC results in Latin America; a feature on CBCs in Colombia; and documenting the effects of Hurricane Ike on the Gulf Coast of Texas.
