Bird data on Christmas Bird Counts must be tallied by officially involved human observers, in designated field parties, who are not only submitting their bird data but their effort data as well.

We have ebird, NC rare bird alert, and many local reporting groups which fill in the gaps of bird occurrence from standard protocol surveys. I agree with Harry that such birds should be left off the official count numbers.

I don't know if there's any way around that, but it makes it tough to compare a count from pre-ebird times to today's counts with any degree of meaning. It also can tend to keep unbirded places still unbirded.
