Let's not forget that for YEARS the ornithological community derided the
Audubon Christmas Bird Counts with many of the same arguments that are being
used against the Xerces / 4JC / NABA / whatever-you-want-to-call-'em Counts.
However, after 100 years of "CBC count data", the sheer bulk of the
sightings over the time frame served to overwhelm the non-scientific aspects
of the data collection and reportage, and serious bird-scientists are mining
the CBC data for trends, etc.
Yes, the 4JCs are a social event, and we stop counting "everything" in
the afternoons to order focus on the species total in order to "beat" the
other regional counts. And yes, my counting technique is certainly
different from Alex's and MG's, but if I do my counting the SAME way in the
SAME areas for 10+ years, there is a good chance that any emerging "trend"
may in fact be worthy of a more rigorous treatment by a "real"
Looking forward to having fun this weekend in Salisbury, CT,
