Adam Green brought up several methodological problems with the analysis of CBC data in the birds and climate change stuy. I completed courses in inferential statistics and in research methodology in grad school so I can appreciate his concerns.
There have been a number of studies done to determine methods that can be employed to analyze the CBC data that produce reliable and meaningful results. One of these was "NONLINEAR POPULATION DYNAMICS OF SIX SPECIES OF FLORIDA CICONIIFORMES ASSESSED BY CHRISTMAS BIRD COUNTS" that was published in the journal Ecological Applications, a peer-reviewed scientific journal published by the Ecological Society of America. Greg Butcher who is one of the researchers in the study at hand was one of the authors. Another salient paper, "ENHANCING THE SCIENTIFIC VALUE OF THE CHRISTMAS BIRD COUNT" , was published in 2005 in the "Auk", the prestigious journal of the American Ornithologist's Union. Dr. Niven, one of the researchers in this research was one of the authors of "A Hierarchical Model for Regional Analysis of Population Change Using Christmas Bird Count Data, with Application to the American Black Duck". That was published in 2006 in "The Condor" which is the journal of the prestigious Cooper Ornithological Society. The authors of "Birds and Climate Change Ecological Disruption in Motion", Daniel K. Niven. Ph.D.,Gregory S. Butcher, Ph.D.,G. Thomas Bancroft, Ph.D.,William B.Monahan, Ph.D, and Gary Langham, Ph.D, are experienced bird/wildlife researchers. I know Greg Butcher and I believe that he would be willing to respond to reasonable questions regarding the methodological issues involved in this research.
