Here's some data from the Chapel Hill counts, standardized by observer effort
(number = Pileated Woodpeckers per 100 party hours).
Year CBC SBC*
1987 3
1988 11
1989 0
1990 3
1991 9
1992 10
1993 3
1994 8 9
1995 4
1996 10 9
1997 5 6
1998 7 9
1999 5 7
2000 14 15
2001 14 11
2002 9 17
*CBC = Christmas Bird Count; SBC = Spring Bird Count
Looks like there's a definite upward trend in the last three years. If you
just look at the pre-2000 data, it's a flat line.
